Blue Heart slot by Amusnet — game artwork
Amusnet · December 2014 wave

Blue Heart

On 3 December 2014 Amusnet shipped four machines. Three of them — Burning Hot, 20 Super Hot and 40 Super Hot — have no documented free-spins round to this day. The fourth was Blue Heart, and its official spec sheet carries a Special Features block that reads: Free Spins. Stacked Wild Symbols.

That is the story here. Amusnet’s 2014 classics are famous for having almost nothing under the bonnet, and we have said so in review after review. This one shipped the same day and got both a bonus round and stacked wilds, and unlike most of the claims we have to hedge in this catalogue, both are on the studio’s own page.

The catch is arithmetic. The quoted 1,000× max win is per line, and there are a hundred lines — so it is worth about 10× your total stake, the thinnest ceiling we have measured on any Amusnet game. Blue Heart shares that number with 100 Super Hot. What it does not share is 100 Super Hot’s complete absence of features and its lower return.

Blue Heart at a Glance

VolatilityLow-Medium

Top line pay1,000× line betAmusnet’s page words this as “1000 x bet per line”, the same phrasing it uses on 20 Diamonds and 20 Super Hot. Spread across a hundred lines that is roughly 10× your TOTAL bet — the thinnest effective ceiling in this catalogue, tied with 100 Super Hot. Note that both major databases write it as “1,000× the bet” without the per-line qualifier, so the sources disagree on the basis; we go with the studio’s wording.
JackpotJackpot CardsThe official description references a “Jackpot Bonus feature” and two databases name Jackpot Cards and its four levels — better sourcing than most of the range. It sits outside the published RTP and is enabled by your operator.

How Blue Heart Plays

Five reels, four rows, a hundred paylines — a 5 × 4 grid with twenty symbol positions, which is a bigger board than the 5 × 3 classics most of this catalogue runs on.

The theme is unusually story-led for a 2014 Amusnet machine. The official description casts you as a bounty hunter recovering stolen jewels, among them “the famous Blue Heart diamond”, and the symbol set is jewels rather than the usual fruit.

Mechanically there are three things happening. Jewel symbols pay left to right along the lines. The diamond wild substitutes and arrives stacked, which on a four-row grid means it can cover a whole reel. And the jewellery scatter triggers free spins. On top of that sits Jackpot Cards, the four-level progressive that can fire at random at the end of any paid spin.

The Story Behind Blue Heart

Amusnet dates Blue Heart 3 December 2014 on its own page. SlotCatalog says 10 July 2014; we prefer the studio’s date and flag the disagreement.

The date is the most interesting fact about this game. Burning Hot, 20 Super Hot and 40 Super Hot all carry that same official 3 December 2014 stamp, and all three are feature-free machines — no free spins, nothing beyond a gamble and the Jackpot Cards progressive that most of the catalogue shares. We have documented that absence repeatedly.

Blue Heart came out of the same door on the same day with a bigger grid, a story, stacked wilds and a bonus round. Whatever Amusnet was doing that December, it was not doing only one thing.

Symbols and Paytable

Amusnet does not publish a full paytable, and we are not going to reconstruct one from sources that disagree. What follows is the symbol behaviour that the official page confirms or that two or more independent sources agree on, with the single-source claims labelled as such.

Diamond (Wild) — stackedThe blue heart jewel is the wild, and “Stacked Wild Symbols” appears in Amusnet’s own Special Features block. That matters: when we found a stacked-wild claim on 20 Diamonds it came from one database and we had to hedge it. Here the studio says it. On a four-row grid a stacked wild can fill an entire reel. What nobody publishes is whether it also substitutes for the scatter, so we are not going to say either way.
Jewellery (Scatter)Pays and triggers from anywhere it lands rather than along the hundred lines, and three or more start the free spins. One source adds that it appears only on reels 2, 3 and 4 — that is single-source, so treat it as reported rather than confirmed. If true it puts Blue Heart in a group with Extra Stars, 20 Burning Hot and Amazons’ Battle, all of which confine a key symbol to the middle three reels.
The jewel ladderTen paying symbols across low, mid and high tiers, with the 1,000× line payout at the top. No source publishes values we would stand behind, so the in-game paytable is the authority.

The stacked wild is the detail worth carrying into a session. On a 5 × 4 grid with a hundred lines, a wild that arrives as a full-reel stack touches a very large number of those lines at once. That is a different kind of win than a single wild completing one payline, and it is the mechanic doing most of the work in this game’s base play.

Bonus Features

🎰

Free spins — officially listed, which is rare here

“Free Spins” sits in Amusnet’s official Special Features block. Two independent sources agree on the detail: three scatters award 10 free spins, with retriggers possible. No source documents a multiplier on those spins, so do not expect one. For context, three of the four games Amusnet released on this same day have no free-spins round at all.

💎

Stacked wilds — also official

“Stacked Wild Symbols” is the second entry in that Special Features block. On a four-row grid a stack can cover a full reel, and with a hundred lines running that reaches a lot of paylines simultaneously. This is the single biggest reason the base game here feels different to the Super Hot line.

🃏

Jackpot Cards — four progressive levels

The official description references a “Jackpot Bonus feature” and two databases name Jackpot Cards directly, with its four card-suit levels. It fires at random at the end of any paid spin and is resolved by matching three suits from twelve face-down cards. It sits outside the published RTP and your operator decides whether it runs.

📉

Volatility rated 2 out of 5 — officially

Amusnet publishes a variance figure for only part of its range, and here it gives 2/5. SlotCatalog says Low-Medium and Casinolandia says low-to-medium, so everyone broadly agrees. Note it is one step above 100 Super Hot’s 1/5 rating despite both being hundred-line games — the free spins and stacked wilds have to be paid for somewhere.

Fixed or adjustable lines? The sources contradict each other

Amusnet’s page says simply “100” — and it is worth noticing that the same studio writes “20 Fixed” on 20 Diamonds and 20 Super Hot, so the missing qualifier looks deliberate. SlotCatalog calls the lines adjustable; Casinolandia calls them fixed. They cannot both be right. Check the client before you assume you can drop lines to lower your stake.

Jackpot Cards — and why it matters more than usual here

Blue Heart carries Amusnet’s four-level mystery progressive. The round can fire at random at the end of any paid spin regardless of what the reels did; twelve face-down cards appear, and you pick until three of one suit show. The suit you complete is the level you win, with Clubs at the bottom and Spades at the top.

The sourcing here is better than we usually get. Amusnet’s own description references a “Jackpot Bonus feature”, and both SlotCatalog and Casinolandia name Jackpot Cards and its four levels explicitly. Compare 20 Diamonds, where the studio said nothing at all and we had to present the whole thing as operator-dependent guesswork.

Two things to keep straight. The progressive sits outside the 96.03% — that figure describes the reels, and the jackpot is funded separately, so it is not a reason to read the game as returning more than it says. And with a base-game ceiling worth roughly 10× your total stake, the jackpot is realistically the only route to a result that would change your session. Check the jackpot panel is above the reels — your operator decides whether it runs at all.

SPADES
HEARTS
DIAMONDS
CLUBS

The Gamble Feature, Properly Explained

Gamble is on the official feature list alongside Autoplay. Casinolandia describes it as guessing a card’s colour — correct doubles the win, wrong forfeits it.

That colour detail is more specific than most of this catalogue supports and it comes from one source, so we would not swear to it. Amusnet leaves the form of its gamble round unstated across most of the range, and the difference matters: a colour guess is close to a coin flip, while picking a suit is not. Look at the actual gamble screen in your client before you use it.

What we like

  • Free spins AND stacked wilds are both in Amusnet’s own Special Features block — not database guesswork
  • 96.03% beats every game in the Super Hot line and the rest of the December 2014 batch bar Burning Hot
  • 5 × 4 grid with stacked wilds means a single wild reel can touch a large share of the hundred lines
  • Jackpot Cards is corroborated by the studio’s own description as well as two databases
  • One of the more complete official spec sheets in the catalogue — RTP, volatility, layout, max win and release date all published
What to watch

  • 1,000× per line across a hundred lines is only about 10× your total bet — the thinnest ceiling in this catalogue
  • Sources contradict each other on whether the hundred lines are fixed or adjustable
  • No multiplier is documented on the free spins, so the round is ten spins of ordinary play
  • The databases disagree with the studio on the max-win basis, and one of them derives a headline figure from treating it as total bet
  • Release date is disputed by five months between the studio and SlotCatalog

How Blue Heart Compares

The first two rows are the comparison that decides this game. Both are hundred-line Amusnet machines quoting the identical 1,000× per line, so both have the same thin effective ceiling.

GameRTPLayout & linesEffective ceilingFree spins
Blue Heart96.03%5 × 4, 100≈10× totalYes — official
100 Super Hot95.76%5 × 4, 100 fixed≈10× totalNone documented
40 Super Hot95.81%5 × 4, 40 fixed≈25× totalNone documented
Burning Hot96.45%5 × 3, 5 fixed≈600× totalNone documented

Against 100 Super Hot the verdict is one-sided. Same board, same line count, same 1,000× per line and therefore the same roughly 10× total-bet ceiling — but Blue Heart returns 0.27 points more and has an officially listed free-spins round and officially listed stacked wilds, where 100 Super Hot has neither. On published figures there is no argument.

The bottom row is the honest counterweight. Burning Hot came out the same day, returns 0.42 points more than Blue Heart, and concentrates 3,000× onto five lines instead of spreading 1,000× across a hundred — which is what pushes its effective ceiling to roughly 600× your total stake. It has no free spins and no stacked wilds. So the choice is real: features and a bigger board here, or return and a ceiling sixty times higher there.

RTP, Volatility and Win Potential

96.03%, verified on Amusnet’s official page and confirmed by SlotCatalog, Casinolandia and Slotsmate without disagreement. That is right around the online average and comfortably above the entire Super Hot line — 100 Super Hot returns 95.76%, 20 Super Hot 95.79%, 40 Super Hot 95.81%.

Volatility is officially rated 2 out of 5. Amusnet publishes a variance figure for only some of its games, so having one is useful, and 2/5 puts Blue Heart level with Burning Hot, Zodiac Wheel, Flaming Hot and Amazons’ Battle. Worth noticing that it is a step above 100 Super Hot’s 1/5 despite the identical grid and line count — free spins and stacked wilds concentrate outcomes, and that shows up as variance.

Now the ceiling, which needs the arithmetic spelled out because the sources disagree. Amusnet’s page says “1000 x bet per line”, exactly the phrasing it uses on 20 Diamonds and 20 Super Hot. Across a hundred lines your total stake is a hundred times the line bet, so 1,000× per line is worth roughly 10× your total bet — the thinnest effective ceiling of any game in this catalogue. Both major databases instead write “1,000× the bet” with no per-line qualifier, and one of them multiplies it by a £1,000 maximum stake to advertise a million-pound win. We go with the studio’s own wording and flag that the sources do not agree on the basis. Either way, Jackpot Cards sits outside it.

Bets, Bankroll and Session Planning

SlotCatalog and Casinolandia both give a range of roughly 0.01 to 1,000 per spin, one in pounds and one in dollars, and they agree on the numbers. Amusnet does not publish a range, and operators narrow it, so treat that as the shape rather than a promise.

There is an open question that affects how you stake. If the hundred lines are adjustable, as SlotCatalog says, you can reduce your total bet by playing fewer of them — but doing so also shrinks how much of the grid a stacked wild can pay across, which is the game’s main mechanic. If they are fixed, as Casinolandia says, the question does not arise. The studio’s own page does not settle it, so the line selector in your client is the only reliable answer.

Playing Blue Heart on Mobile

Amusnet lists desktop and mobile on the official page. The 5 × 4 grid means twenty symbol positions rather than the fifteen most of these classics use, which is more to fit on a phone — but the jewel symbols are large, saturated and high-contrast, so they hold up better at small sizes than a detailed themed symbol set would.

The thing worth knowing is that a hundred paylines is a lot of win lines to draw. When a stacked wild lands and pays across many of them at once, the animation is busy. That is a presentational note, not a fault.

Five Things to Know Before You Spin

  1. Read the max win as per line, because the studio does. Amusnet writes “1000 x bet per line”. Across a hundred lines that is about 10× your total stake. Any source quoting you a million-pound win has multiplied the figure by a maximum bet and dropped the ‘per line’.
  2. Check whether you can deselect lines. SlotCatalog says the hundred lines are adjustable, Casinolandia says they are fixed, and the official page declines to say. It changes how you control your stake, so look before you spin.
  3. The stacked wild is the mechanic, not the free spins. A wild that fills a reel on a four-row grid touches a large share of a hundred paylines. That is where the base game’s wins come from.
  4. Do not expect a multiplier in the bonus. Ten free spins on three scatters, retriggerable, and no source documents any multiplier attached. It is ten more spins, not enhanced ones.
  5. Look for the jackpot panel above the reels. With a base-game ceiling around 10× your total bet, Jackpot Cards is realistically the only route to a session-changing result — and operators decide whether it runs.
  6. If the thin ceiling is the dealbreaker, Burning Hot shipped the same day. 96.45%, five lines, and an effective ceiling roughly sixty times higher. You give up the free spins and the stacked wilds to get it.

Who Blue Heart Is For

This suits a player who likes the 2014 Amusnet look and feel but has been frustrated by how empty those machines are. Blue Heart is the same era and the same studio with an actual bonus round, actual stacked wilds and a better return than the Super Hot line — and both features are on the studio’s own sheet rather than inferred from a database.

It is the wrong game if the ceiling matters to you. About 10× your total bet is as thin as this catalogue gets, and no amount of features changes that arithmetic. If you want a real top end from the same December 2014 batch, Burning Hot concentrates its pay onto five lines and is roughly sixty times higher for it. And if you specifically want a hundred-line Amusnet game, this is simply the better one — 100 Super Hot gives you the same thin ceiling with a lower return and no features at all.

Blue Heart FAQ

What is the RTP of Blue Heart?
96.03%, verified from Amusnet’s official game page and confirmed by SlotCatalog, Casinolandia and Slotsmate. That is around the online average and above the whole Super Hot line, including the 100-line 100 Super Hot at 95.76%.
Does Blue Heart have free spins?
Yes, and unusually for this catalogue it is on the studio’s own sheet — “Free Spins” appears in Amusnet’s official Special Features block. Two independent sources agree on the detail: three scatters award 10 free spins, with retriggers possible. No source documents a multiplier, so treat them as ten ordinary spins.
What is the maximum win in Blue Heart?
Amusnet quotes 1,000× the bet per line. Across a hundred lines that is roughly 10× your total stake — the thinnest effective ceiling in this catalogue. Be aware that SlotCatalog and Casinolandia both write it as “1,000× the bet” without the per-line qualifier, and one derives a million-pound figure from a maximum stake. We go with the studio’s wording. Jackpot Cards sits outside it either way.
Are Blue Heart’s 100 paylines fixed or adjustable?
The sources contradict each other and we are not going to pick a side. Amusnet’s page says only “100”, with none of the “Fixed” qualifier it uses on games like 20 Diamonds. SlotCatalog says adjustable; Casinolandia says fixed. Check the line selector in your client.
Does Blue Heart have stacked wilds?
Yes — “Stacked Wild Symbols” is listed in Amusnet’s official Special Features block. On a 5 × 4 grid a stack can fill an entire reel, which with a hundred lines running touches a lot of them at once. Whether the wild also substitutes for the scatter is not published.
Does Blue Heart have a progressive jackpot?
Yes, the four-level Jackpot Cards. The official description references a “Jackpot Bonus feature” and two databases name Jackpot Cards and its card-suit levels. It fires at random after a paid spin, sits outside the published RTP, and is enabled by your operator — so check the panel above the reels.
When was Blue Heart released?
3 December 2014 according to Amusnet’s own page — the same official date as Burning Hot, 20 Super Hot and 40 Super Hot. SlotCatalog says 10 July 2014; we prefer the studio’s date and note the disagreement.
Is Blue Heart better than 100 Super Hot?
On published figures, yes. Both are hundred-line Amusnet games with the same 1,000×-per-line figure and therefore the same roughly 10× total-bet ceiling. But Blue Heart returns 96.03% against 95.76%, and it has officially listed free spins and stacked wilds where 100 Super Hot has neither.

Our Verdict

7.8/ 10

The 2014 classic that actually got features

We have spent a lot of these reviews explaining that Amusnet’s December 2014 machines have nothing in them — no free spins, no special wild behaviour, a gamble and a shared progressive and that is the lot. Blue Heart shipped on that same official date and its spec sheet lists a free-spins round and stacked wild symbols, in the studio’s own words. That makes it the most interesting game of the batch, and it is why it scores where it does.

The features are real and they change how the game plays. A stacked wild on a 5 × 4 grid can fill a reel and pay across a large share of a hundred lines at once, which is a genuinely different base game to the Super Hot line’s flat classic reels. Ten free spins on three scatters is a modest round with no documented multiplier, but a modest round beats none. And at 96.03% the return is better than anything else with a hundred lines in this catalogue.

The ceiling is the problem and it cannot be argued away. Amusnet quotes 1,000× per line and there are a hundred lines, so the base game tops out around 10× your total stake — the thinnest figure we have measured here. Two databases report that number in a way that makes it look a hundred times larger, which is worth knowing before you read anyone else’s review. Jackpot Cards is the only real top end, and only if your operator runs it.

So: comfortably the best hundred-line Amusnet game, and the only 2014 classic that gives you something to play for between spins. If you want a ceiling instead of features, Burning Hot came out the same day and is sixty times higher. If you want both, this catalogue does not have it.
