10000 BC 2 DoubleMax

10,000 BC 2 DoubleMax is 4ThePlayer's follow-up to its original mammoth-sized prehistoric slot, and it doubles down on the same idea that made the first game work: pairing two of Yggdrasil's signature mechanics, GigaBlox and DoubleMax, in a single title. Where the original release set its scene among gentle prehistoric meadows and mountains, the sequel splits its landscape between snow-covered ground and a river of lava beneath an active volcano, a visually striking contrast that also ties into some of the game's newer features.

GigaBlox and DoubleMax explained

The grid runs a 5x5 layout with 50 fixed paylines, and one of the more notable changes from the original is a lower RTP, now set at 94.0%, reflecting 4ThePlayer's broader shift toward that return band across recent releases amid tightening regulatory pressure in various markets. Volatility remains high. Players can activate the Golden Bet option, which raises the stake by 25% in exchange for doubling the chance of triggering free spins, a worthwhile trade-off for anyone specifically hunting the bonus round rather than grinding the base game. GigaBlox brings oversized, merged symbol blocks into play, while DoubleMax doubles the active win multiplier with each consecutive cascade, and when both mechanics fire in the same spin the results can escalate quickly.

Symbols and paytable

On the paytable, 10-to-Ace card symbols rendered as stone-carved gems make up the lower tier, paying a modest 0.3x to 0.35x the stake for five-of-a-kind, while bears, wolves, woolly rhinos, sabre-tooth tigers and woolly mammoths sit above them, worth 0.4x up to 1.25x for a full line of the top symbol. Wilds appear only as part of the game's dedicated Fireball Wilds feature rather than landing freely across the reels, and a wild-only combination doesn't pay out on its own.

RTP, volatility and stakes

Betting runs from 0.20 up to 100 per spin, giving a reasonably wide range for both cautious and assertive players, and the maximum win sits at 10,000x the stake, a genuinely serious ceiling that reflects just how far the combined GigaBlox and DoubleMax systems can stretch a winning sequence when they align.

Final word

For players who enjoyed the original 10,000 BC DoubleMax and want more of the same core formula with a fresh volcanic setting and a slightly adjusted RTP, the sequel delivers a familiar but visually distinct experience. It's a high-volatility title through and through, best suited to players comfortable riding out quieter spells in exchange for a shot at that five-figure multiplier.
