Relax Gaming Launches Nuclear Tumble With 46,656 Ways & Meltdown Mode
Relax Gaming has officially launched Nuclear Tumble, the newest entry in its signature stone-breaking Tumble franchise developed in collaboration with the CasinoGrounds streaming community. Set on a post-apocalyptic mutant farm powered by a toxic radiation leak, the release combines a 6×6 cascading grid (up to 46,656 ways to win) with drop-down Bottle Cap cash prizes, Exploding Bombs, and three tiered Free Spins modes.
Following recent studio launches such as Cloudforge and Money Train 5, Nuclear Tumble shifts the math profile to medium-high volatility with a 96.10% default RTP and a 5,000× maximum win cap.

Irradiated Blockers, Bottle Cap Cash Drops & Meltdown Mode
Every spin begins on a 6×6 grid partially sealed by irradiated stone blockers. Landing a winning combination across 3 or more adjacent reels triggers a tumble cascade that destroys orthogonally adjacent stone blocks and opens additional ways to win.
Crushing stone blockers can uncover three special symbols underneath the rubble:
- Bottle Cap Cash Prizes (Bronze, Silver & Gold): Reveal instant bet multipliers up to 2,500× on top-tier Gold caps. To award its cash value, a Bottle Cap must tumble all the way down to the bottom row of the 6×6 grid before the cascade sequence ends.
- Exploding Canister Bombs: Detonate across their entire horizontal row and vertical column, destroying all regular paying symbols and stone blockers while leaving Bottle Cap cash prizes and Scatters intact so they drop closer to the bottom collection row.
- Meltdown Mode: Triggers automatically whenever you clear every stone blocker on the 6×6 board and no further winning cascades remain. Meltdown Mode wipes all regular symbols off the screen, dropping any active Bottle Caps straight to the bottom row for guaranteed collection.
Regular, Super & Ultra Free Spins Progression
Uncovering and landing nuclear container Scatter symbols triggers the Free Spins round, with higher scatter counts or progression upgrades unlocking Super Free Spins and Ultra Free Spins:
| Bonus Tier | Core Advantage | Bottle Cap Multiplier Potential |
|---|---|---|
| Regular Free Spins | Enhanced blocker destruction & extra bomb frequency | Bronze, Silver & Gold Bottle Caps active |
| Super Free Spins | Upgraded cash prize distribution on cleared blockers | Higher weighting toward Silver & Gold caps |
| Ultra Free Spins | Maximum cash-drop density & Meltdown Mode frequency | Top-tier Gold Bottle Caps worth up to 2,500× |
