Like its predecessor, the 10,000 BC 2 DoubleMax slot is vibrant and full of colour. Set against a snowy Ice Age landscape, the background reveals a recently erupted volcano spilling lava across a valley. During the Free Spins feature, the eruption intensifies, transforming the snowy scenery into a fiery red expanse—things really heat up here!

The soundscape immerses you with tribal music and animal calls, including the trumpeting of woolly mammoths. Traditional slot sounds mix in, and during the free spins, the music shifts to an electric beat. 

The grid is brightly coloured to match the background, and on the reels, you will find prehistoric animals, including extinct giants like the woolly mammoth and sabre-toothed tiger.

Here’s a rundown of all the symbols:

• Wolly mammoth: 3, 4 or 5 = 0.32, 0.48 or 1.00 x the bet
• Sabre-tooth tiger: 3, 4 or 5 = 0.24, 0.32 or 0.48 x the bet
• Rhinoceros: 3, 4 or 5 = 0.20, 0.28 or 0.40 x the bet
• Wolf: 3, 4 or 5 = 0.16, 0.24 or 0.32 x the bet
• Bear: 3, 4 or 5 = 0.08, 0.12 or 0.24 x the bet
• K & A: 3, 4 or 5 = 0.12, 0.20 or 0.28 x the bet
• Q, J & 10: 3, 4 or 5 = 0.8, 0.12 or 0.24 x the bet 
• Scatter: 3+ trigger Free Spins feature 
• Wild: substitutes for all symbols apart from the scatter
  
  

10000 BC 2 DoubleMax Mobile

4ThePlayer is known for providing its players with an excellent mobile experience. The studio has trademarked its Big Reel Portrait Mode, which means that when playing in portrait mode,  the game looks stunning and fully utilises the screen which you can see above. The game is equally impressive on a desktop and tablet.

There are 6 bonus features to enjoy as part of the 10000 BC 2 DoubleMax slot game: Cascades, Gigablox, DoubleMax, modifier features, Free Spins and Feature Buy.

Cascades

When a win occurs on the grid, the winning symbols disappear and new symbols replace them from above. This gives you more opportunities for wins.

Gigablox 

This game uses Yggdrasil Gaming’s popular Gigablox feature, which means that gigantic symbols can appear on the grid. The huge symbols can appear in 2x2 or 3x3 formations and these massive symbols can lead to more wins. You can see the bear as a 2x2 symbol below.

DoubleMax

Each win doubles your win multiplier and creates a wild symbol on the reels. The maximum win multiplier value is 2,048x.

Modifier features

There are 5 modifiers that can appear on any spin, which are:

• Fireball Wilds:  the volcano may launch 1 to 3 wild symbols onto the reels during a spin or drop.
• Multiplier Inferno: a fireball from the volcano may hit the win multiplier to double it.
• Lava Flow: Lava may cover a reel, and all symbols may be changed to copies of the same symbol. This will not create wilds or scatters.
• Mammoth Explode: During any non-winning spin, the Mammoth may hit the reels to destroy symbols, causing a dropdown and a guaranteed win. The win multiplier increases when this happens. Plus, during this feature, the Fireball Wilds also activates.
• Mammoth Shuffle: During any non-winning spin, the Lava Flow feature may trigger on a reel. The Mammoth then hits the reels, pushing the Lava Flow reel to the left. On following drops, this reel moves 1 position at a time back to the right until it reaches the rightmost reel or does not create a win.
  
  

Free Spins

Landing 3 or more scatters triggers the Free Spins feature. Landing 3, 4, or 5 scatter symbols awards 10, 15, or 20 free spins, respectively. During this feature, the win multiplier does not reset until the feature is finished. Lava Flow, Fireball Wild, and Multiplier Inferno can trigger during free spins, but Mammoth Explode and Mammoth Shuffle cannot. 

Feature Buy

If you're a non-UK player, you can utilise the Feature Buy, where there are 2 options available:

• Multiplier Spin: Play a single spin with a boosted win multiplier for 125 x the bet
• Free Spins: Instantly trigger the Free Spins feature for 100 x the bet.

I’m always keen on historical-themed slots, and 10,000 BC 2 DoubleMax doesn’t disappoint. Described as offering "ice-cold thrills with red-hot prizes," the game delivers on its promise. The contrast between the scorching volcano and the freezing Ice Age landscape makes for a unique theme.

Like the original 10,000 BC DoubleMax, this sequel is vibrant, with eye-catching backgrounds, animations and large prehistoric animals that look fantastic on screen. In this release, 4ThePlayer combines the DoubleMax multiplier feature with Yggdrasil Gaming’s Gigablox, and they work brilliantly together. Landing a 3x3 symbol with a high multiplier (up to 2,048x) offers superb win potential.

The modifier features are another highlight; much like a festive box of chocolates, there’s something for everyone. My personal favourite was the Fireball Wilds, which triggered frequently during testing. Visually, the erupting volcano spewing fireball wilds onto the reels looks fantastic. Lava Flow is also impressive, transforming a reel so all symbols align into matching copies.

If you enjoy slots with a prehistoric theme, you should try out the Primal Megaways slot game.

One drawback is the 94% RTP, which is below the 96% industry average and typical for recent 4ThePlayer games. My last 4ThePlayer review, which covered the 4 Fantastic Vikings Go Fishing slot slot gave the game a 4.5 out of 5. which is definitely worth a spin.

The 10,000 BC 2 DoubleMax slot earns a strong 4.3 out of 5 from me for its vibrant design and excellent bonus features. 4thePlayer is a studio created by slot enthusiasts, and this shines through in its games.
