10000 BC 2 DoubleMax

Distributed through Yggdrasil's network under the studio's partner programme, this version of 10,000 BC 2 DoubleMax delivers the same 4ThePlayer-built Ice Age slot found elsewhere, but it's worth breaking down purely on its own mechanical terms for anyone weighing it up as a Yggdrasil-branded release.

The DoubleMax multiplier system

The core system here is the DoubleMax multiplier: every consecutive win doubles the active multiplier applied to subsequent wins, and, critically, that multiplier doesn't reset once free spins begin, meaning any momentum built in the base game carries straight through into the bonus round. Wins are generated on a 5-reel, 5-row grid across 50 fixed paylines, with matching symbols connecting on adjacent reels from left to right. Every win triggers the game's cascade mechanic, clearing the winning symbols and dropping new ones into the empty spaces, which is what keeps that DoubleMax multiplier climbing across a single spin.

Theme and free spins

Thematically, the reels are populated with the icons of a frozen prehistoric world, mammoths, sabre-tooth tigers, primitive tools and survival-themed symbols set against snowy tundra backdrops, all animated with a fair amount of energy when cascades and multiplier increases fire off in sequence. The Free Spins round triggers once enough scatter symbols land, awarding a variable number of spins where the persistent DoubleMax multiplier keeps building without resetting between cascades, the game's clearest route to its bigger prizes. A bonus buy option is also available on supported platforms for players who'd rather skip straight to the free spins round, with all the core mechanics remaining fully active once purchased.

RTP, volatility and betting

The numbers back up the aggressive design: RTP sits at 94.0%, volatility is rated high, and betting runs from 0.2 up to 100 per spin. The maximum win reaches 10,000x the stake, a genuinely large ceiling that's realistic to approach specifically because the DoubleMax multiplier persists rather than resetting with every new cascade, long chains during free spins are where this game does its best work.

Verdict

For players already familiar with Yggdrasil's DoubleMax mechanic from other titles in the family, this Ice Age dressing offers a fresh theme without changing the underlying formula much, which should make the multiplier system feel immediately intuitive. Those new to DoubleMax slots will want to pay close attention to how quickly the multiplier can escalate once cascades start chaining.
