10000 BC DoubleMax

Before the sequel came along, there was the original 10000 BC DoubleMax, 4ThePlayer's first attempt at mashing together two of Yggdrasil's most explosive mechanics, GigaBlox and DoubleMax, in one prehistoric-themed package. It's a genuinely significant release in that sense: the first time these two systems had been combined in a single slot, and the template the sequel would later build on.

The original GigaBlox/DoubleMax pairing

The setting is a bright, colourful take on the stone age, animal-skin clothing, primitive tools and an overall cheerful visual tone that leans more playful than gritty. The grid runs a 5x5 layout with 50 fixed paylines, and betting is set from 0.10 up to 10 per spin, a notably accessible range compared with many of 4ThePlayer's higher-stake releases. Players can also opt into the Golden Bet, which raises the stake by 25% in return for doubling the odds of triggering free spins, useful for anyone specifically targeting the bonus round.

Symbols and features

On the paytable, 10-to-Ace card symbols form the lower tier, paying 0.3x to 0.35x the stake for a five-of-a-kind line, while bears, wolves, woolly rhinos, sabre-tooth tigers and woolly mammoths sit above them, worth up to 1.5x for the top combination. A campfire symbol acts as the wild, substituting for all standard paying symbols across the grid. Two named features round out the base game alongside the core GigaBlox and DoubleMax mechanics: Mammoth Explode and Mammoth Shuffle, both designed to shake up the grid outside of the free spins round and create additional opportunities for winning combinations to form.

RTP, volatility and betting range

According to the published data, RTP sits at a strong 96.0% and volatility is rated low, a genuinely unusual pairing for a slot boasting a 10,000x maximum win, suggesting that while dramatic multiplier runs are possible when GigaBlox and DoubleMax align, the overall distribution of outcomes may be gentler than the eye-catching ceiling figure alone would suggest.

Final take

Whether that combination of an accessible betting range, strong RTP and headline-grabbing win potential appeals will come down to personal taste, but as the original pairing of GigaBlox and DoubleMax, 10000 BC DoubleMax remains a notable entry in 4ThePlayer's catalogue.
