Blast 1000 is released on 16 November 2026, so its figures are pre-release data from the game sheet. Release dates, hit frequencies and lower RTP versions come from bigwinboard and are not officially confirmed by Pragmatic Play.
How to read the table
RTP (return to player) is the share of all stakes a game pays back over millions of spins. At 96.71%, the long-run average return is £96.71 for every £100 staked. Your own session can land far above or below that.
Max win is the cap on a single round, as a multiple of your stake. Once a round reaches it, the round ends. It tells you the ceiling, not how often you will get near it.
Odds show how rarely that cap is hit: 1 in 62,459 spins on Frozen Lake, but 1 in 14,321,518 on Xmas Xtreme. The cap and the odds do not always move together, so read both.
Volatility describes how wins are spread. Medium means smaller, steadier returns; high means long quiet spells with bigger paydays. Sources do not always agree: Frozen Lake and Xmas Xtreme are listed as high, though some sources say very high, and Christmas Big Bass Bonanza appears as high on bigwinboard but medium elsewhere.
Lower RTP versions casinos may run
Pragmatic Play offers each game in three RTP versions, and the casino chooses which one to use. These are the figures reported by bigwinboard:
- Blast 1000: 96.50%, 95.50% or 94.50%
- Frozen Lake: 96.07%, 95.07% or 94.07%
- Xmas Xtreme: 96.07%, 95.08% or 94.05%
- Christmas Bash: 96.71%, 95.67% or 94.60%
- Christmas Catch: 96.08% (96.07% when buying free spins), 95.07% or 94.07%
- Christmas Big Bass Bonanza: 96.71%, 95.67% or 94.62%
To check which one you are playing, open the game and tap the “i” button. The rules screen states the theoretical RTP of that build. If it shows a lower figure than the top one, the same game may be set higher at another casino.
Which Christmas Big Bass to pick
- Newest and biggest cap: Blast 1000, 20,000× at odds of 1 in 3,820,474, with medium volatility per the game sheet.

What the caps mean at UK stakes
In the UK, an online slot spin costs at most £5, or £2 if you are 18–24. At £5, the Blast 1000 cap of 20,000× equals £100,000; at £2 it is £40,000. At £1 a spin, the 5,000× cap on Frozen Lake is £5,000, and the 2,100× cap on the Bonanza is £2,100. These are ceilings for one round, reached very rarely. Choose a stake you could lose many times over without it hurting.
