A slot series is how most people actually look for games: not one title, but every version of the one they already like. These pages hold the complete set for five of the biggest series in the library - 110 free demos in total, each playable in the browser on play credits with no account, no deposit and no download.
The five collections
Each page lists every game in that series, ordered by how often players opened it this week, with the studio’s own published specs where they exist.

How a slot series actually works
A studio builds one engine, finds it works, and then rebuilds it. What changes between versions is rarely what players assume: the core mechanic usually stays identical, and the differences sit in the grid, the ways count, how the bonus is reached, or the theme.
The names are a specification, not marketing
Pragmatic Play names its builds systematically, which makes a series far easier to read once you know the vocabulary. A number such as 1000 or 2500 is the ways count on the grid. Super Scatter changes how the bonus round is triggered. Dice, POP and Pachi are builds made for markets where the standard version is not offered. Anything carrying a season in its name is a re-theme of a game already in the line.
Blueprint Gaming layers features instead: Jackpot King and Rapid Fire Jackpots add a shared progressive on top of an existing game, and Fortune Play is a multi-stake build. Megaways, licensed from Big Time Gaming and used by both studios, replaces fixed lines with a ways count that changes on every spin.
One series does not always mean one studio
Fishin’ Frenzy is the clearest case here: Blueprint Gaming builds one half of the line and Reel Time Gaming the other, which is why two games with near-identical names can behave differently and publish different returns. Big Bass is almost entirely Pragmatic Play, with two entries from ReelPlay. Every card and table on these pages names the studio behind that specific game for exactly this reason.
What we leave out, and why
Casinos commission re-skinned copies of popular games carrying their own brand. They play identically to the original and nobody searches for them, so they are left out rather than padding a series with duplicates. We also exclude games from other series that merely carry a jackpot suffix from this one - a game sitting on the Big Bass jackpot network is not a Big Bass game.

Slot series FAQ
What is a slot series?
A series is one game engine released again and again with changes - a different grid, a higher ways count, a seasonal re-theme or an extra feature layer. The core mechanic stays the same, which is why players who like one entry usually want the rest.
How many games are in these five series?
124 in total, 110 of which have a free demo you can open right now. Between them they were opened 77,947 times across the SlotsLaunch network this week.
Which series game is played most right now?
Gates of Olympus 2500, with 25,490 plays across the network this week. The order on every page here comes from that daily feed rather than from our own opinion.
Can I play all of them for free?
Yes. Every demo on these pages runs on play credits in your browser with no account, no deposit and no download. Free play uses the same maths as the real game; only the balance is not real.
