How the Grid and Gigablox Work
The game runs on a 5×5 grid with 50 paylines. Gigablox symbols land up to 3×3 in size but count as individual 1×1 symbols when part of a winning combination. When a win lands, those symbols drop away and new ones cascade down – this is where the DoubleMax multiplier kicks in.
Premium animal symbols pay between 0.4x and 1.5x your stake for five of a kind. The campfire Wild substitutes for any pay symbol to complete or improve wins. No other premium mechanics clutter the base game – Gigablox and cascades are the core engine.
DoubleMax Multiplier and Cascades
The DoubleMax multiplier doubles with every consecutive cascading win. A wild symbol spawns in an empty position before the next batch drops. Here’s the critical rule: the multiplier resets to 1x between base game spins, but during the bonus round it never resets – it keeps building for the entire free spins session.
In the video review, a player hit 7 free spins and watched the multiplier climb to 32x on the first spin, then 256x by the final spin. The slot itself notes that multipliers can exceed 4,096x, though the stated maximum payout is 10,000x your stake.
Mammoth Modifiers
Two random modifiers can trigger on non-winning spins, especially during free spins. The Mammoth Explode feature hits the grid to destroy symbols and trigger a guaranteed cascade – the DoubleMax multiplier then doubles as normal. The Mammoth Shuffle requires a 3×3 Gigablox on the rightmost reel; the Mammoth moves it to the leftmost side for a guaranteed win, and affected reels nudge right on subsequent cascades.
These modifiers turn dead spins into winners more often during the bonus round, which is when the multiplier is stacking without reset.
Free Spins and Bonus Buy
Land 3, 4, or 5 scatter symbols anywhere to trigger 7, 10, or 15 free spins respectively. The DoubleMax multiplier never resets during this entire feature – every cascade keeps doubling from where it left off. The Mammoth modifiers hit more frequently in free spins as well.
Non-UK players can purchase the bonus round for 100x the stake. This guarantees at least 3 scatters on the next spin, giving immediate entry to free spins.
Golden Bet Feature
Turn on the Golden Bet feature between spins for an extra 25% per spin. The trade-off: your chances of triggering the bonus round double. This is a straight cost-versus-odds tool – no hidden mechanics, just higher spin cost for better scatter odds.
RTP / Volatility / and Bet Range
| Metric | Value |
|---|---|
| RTP | 96% |
| Volatility | Medium-High |
| Min Bet | 0.1 |
| Max Bet | 10 |
| Max Win | 10,000x stake |
96% RTP is solid mid-range. Medium-High volatility means wins cluster around the bonus round; base game can feel quiet. Bet range runs 0.1 to 10 per spin, making it accessible to most bankrolls.
What Makes It Different
This is the first slot to combine Gigablox and DoubleMax in one game. Yggdrasil created both mechanics; 4ThePlayer built the slot. The pairing is genuinely powerful – massive symbols land frequently enough to trigger cascades, and the multiplier has room to grow. The bonus round is where the slot shows its teeth: a non-resetting multiplier in free spins can spiral fast if cascades keep firing.
Animation on cascade drops is deliberately slow, which some players find immersive and others find tedious. The trade-off is clarity – you watch the multiplier climb with each drop.
