The volcano looming over 10000 BC 2 DoubleMax isn’t there for the postcard. It feeds almost every feature on the reels, firing wilds across a snowbound 5×5 grid, doubling live win multipliers, and drowning columns in lava while a drumbeat keeps time underneath.
4ThePlayer has built its sequel around one idea borrowed from Yggdrasil’s toolkit, the DoubleMax multiplier that doubles after every win and climbs as high as x2,048. That ladder, far more than the chunky Gigablox blocks sharing the screen, is what gives the game its bite.
Wins here don’t just pay, they clear room. Every winning combination lifts its symbols off the grid, drops fresh ones into the gaps, and doubles a running win multiplier that opens at x1 and steps through x2, x4, x8 and onward to a cap of x2,048.
If any slice of a Gigablox lands in a win, the whole oversized block disappears with it. The multiplier holds for as long as the drops keep paying and resets the instant a dropdown comes up empty. Gigablox bring the visual weight, fusing single symbols into 2×2 or 3×3 squares, yet their effect stays modest next to that doubling climb, which is why the title leans on DoubleMax rather than the bigger blocks.
Five modifiers can break into a spin, and they split by temperament. Fireball Wilds sends one to three wilds arcing onto the reels after a win, while Multiplier Inferno lobs a fireball at the win multiplier and doubles it outright. Lava Flow swamps an entire reel and turns every position on it into copies of a single symbol.
The two Mammoth features are the odd pair. Both fire only when a spin or drop has failed to pay. Mammoth Explode batters symbols off a dead board to force a guaranteed win and drags a burst of Fireball Wilds along with it. Mammoth Shuffle plants a Lava Flow reel hard against the left edge, then nudges it one step rightward on each following drop until the wins run out. Neither lifts your top end by a penny. They exist to rescue spins that would otherwise have handed you nothing, which is much of why the screen stays busy even when your balance is sitting still.
Three or more of the arrowhead scatters open the free spins round, awarding 10, 15 or 20 spins for three, four or five symbols. The spin count isn’t really the prize, though. Right through the feature the win multiplier never resets between drops, so it can keep doubling from one spin into the next and reach heights standard play rarely allows. Mammoth Explode and Mammoth Shuffle sit the round out, while the volcano’s wild and multiplier tricks all stay live. There’s no retrigger on offer.
If waiting isn’t your style, two shortcuts jump ahead, and their pricing is the talking point. The full free spins round costs 100x your stake. A lone Multiplier Spin, a single spin that opens with the win multiplier already raised, costs 125x. Paying more for one spin than for an entire bonus tells you how widely that solitary spin can swing. Both buys, like the Golden Bet that adds 25% to your stake to double your free spins odds, work only from the base game.
10000 BC 2 DoubleMax is unusually candid about what high volatility means for you. Buried in its info screens sits a stats panel that pegs the best win over a 100-spin run at roughly 54x your stake for the average player, climbing to 192x for one player in ten and 515x for one in a hundred. Held up against a 10,000x maximum, that spread is a useful splash of cold water before any lava starts flowing.
You set your stake with the bet steppers, anywhere from £0.20 to £100 a spin, and the 50 paylines are fixed, paying from the leftmost reel rightward. The default return runs at 94%, a step down from the first game and a sign of where 4ThePlayer’s slot catalogue has drifted under tighter regulation. Some operators load a 90.5% build instead, so the info panel is worth opening to see which version you’ve landed on. Either way, the free demo runs the identical maths, letting you watch the volcano cycle through its tricks without staking a thing.
The figures below assume a £1 spin. Nudge your own stake up or down and the payouts shift to match.

The fiery wild and the arrowhead scatter both sit outside this table. The wild substitutes for every beast and royal, carries no value of its own, and only ever reaches the reels through the volcano’s Fireball Wilds. The scatter pays nothing directly, landing anywhere on the grid for the single purpose of opening the free spins. Because wilds hold no worth on their own, a line built only of wilds returns nothing, so each one needs a paying symbol beside it to count.
