Nuclear Tumble

Nuclear Tumble Slot Overview

Relax Gaming slots created in cooperation with Casinogrounds are always entertaining. Some of these collaborations include Beast Gains and Iron Bank 2.

Nuclear Tumble resembles these games in its look, but its soundtrack is similar to another nuclear waste-themed slot, xWays Hoarder xSplit, with its muffled sound.

In Nuclear Tumble, we play with Cash Prizes that can suddenly pay out huge amounts, exploding bombs and Free Spins with a progress bar.

Nuclear Tumble is scheduled for release in the UK on October 29, 2026, with a max win of 5,000x the bet.

Theme & Visuals

Nuclear Tumble is based on a nuclear waste theme, and you can see reactors in the village background.

Something tells me that you shouldn’t want to eat those fruits lying around here and there.

The background shifts from a clear day to a hazardous, full-on nuclear scene.

How to Play Nuclear Tumble

Nuclear Tumble is played on a 6×6 grid, with 46,656 ways to win.    

You win when you land 3 or more matching symbols on adjacent reels, starting from the leftmost reel. The game then removes winning symbols and replaces them with new ones falling down. These tumbles then continue as long as new wins form.

You can play Nuclear Tumble at UK casinos with bets from 20p up to £5.

Max bets per age group in the UK:

• Aged 18-24: Maximum stake of £2 per spin.
• Aged +25: Maximum stake of £5 per spin.

Nuclear Tumble is a medium-to-high-volatility slot that offers a max win of 5,000x the bet.

Slot Features & Bonus Rounds

The main goal is to clear the path so cash prizes reach the bottom layer of the grid, where they are collected.

Exploding Bombs

The bombs explode at the end of cascade sequences and destroy all non-cash symbols above and to the sides of the bomb.

Cash Prizes

Cash Prizes clear any blockers directly underneath them, and the goal is to reach the bottom layer to collect them.

Meltdown

The Meltdown feature triggers when all blocker positions are cleared from the grid.

All symbols except cash symbols are removed, and new symbols land with a chance to land more and higher-value cash values.

Free Spins

3 Scatters trigger the free spins. If a Super Scatter or Ultra Scatter is among the triggering scatters, then you play even better free spins.

• 3 Scatters: 6 Free Spins
• 3 Scatters including one Super Scatter: 8 Free Spins and start on level 2
• 3 Scatters including one Ultra Scatter: 8 Free Spins and start on level 3

During the free spins, you collect coins to progress through the levels to earn higher cash prize values.

Gamble Option

You have the option to gamble your free spins for a higher level. However, a failed gamble make you lose all your free spins.

Symbols & Payouts

Nuclear Tumble features 9 regular pay symbols.

• Low-paying symbols can pay up to 0.20x the bet for 6 of them on adjacent reels.       
• High-paying symbols can pay up to 1x the bet for 6 matching bears.       

CasinoWizard’s verdict: Nuclear Tumble is fun (7.5 out of 10)

If the previous releases from the collaboration between Relax Gaming and Casinogrounds have taught us anything, it’s that these games become popular for good reason.

Nuclear Tumble will join this club. The theme is likeable, and the game offers plenty of variety and excitement to explore. Most importantly, it feels busy, with bombs exploding regularly to make space for new symbols and, hopefully, cash prizes.

Cash prizes can also turn a lousy session into a brilliant one in a split second if a high-value prize lands in the right position, and you manage to collect it.

Free Spins follow the same concept, except you can upgrade the level and values of the cash prizes by collecting cash symbols.

The 5,000x max win potential isn’t bad either, but it may be slightly surprising, as slot streamers often prefer even higher max wins to aim for.

However, the essential point is that Nuclear Tumble is entertaining.

Final verdict: 7.5 out of 10.

Nuclear Tumble is officially released on October 29, 2026.
