Enjoy some cartoon caveman chaos in Cool Stone Age, a 5 reel, 20 payline slot from Pragmatic Play. This madcap prehistoric adventure comes with a driving bonus that awards instant win prizes as well as a free spins feature. Head back in time from between 20p and £100 per spin.

Cool Stone Age is a nicely designed game – the images are drawn cartoon-style and include prehistoric TVs, mobile phones, walking boots and computer. They’re joined by a woolly mammoth, dinosaur and 3 Stone Age humans. The most lucrative of these by far is the mad looking scientist holding the test tube – land 5 of him on a payline for a bumper payout of some 10,000 coins.

The brown brontosaurus is the game’s wild – it replaces everything apart from the scatter and bonus symbols. Both of these symbols trigger a feature.

Caveman Cruiser Bonus feature – you’ll need to land 3 or more of the Stone Age car to activate this feature. Once triggered, you’ll go for a spin in your stonemobile. At every fork in the road, choose to steer left or right. Every appliance that you collect awards a cash prize. Take a wrong turn and you’ll be faced with a prehistoric beast who’ll stop you in your tracks. 2 wrong turns and the feature ends. The prizes on offer here depend on the number of bonus symbols that triggered the feature:

  • 3 bonuses = 15 to 270 coins
  • 4 bonuses = 50 to 900 coins
  • 5 bonuses = 250 to 4,500 coins

Free Spins feature – to trigger these, you’ll need to land at least 3 of the Stone Age cottage scatter symbol anywhere on the reels. 3 will get you 5 free spins. 4 awards 10 with 20 on offer if you’re lucky enough to hit 5 scatters.

Cool Stone Age is a jaunty affair that has its tongue firmly in its cheek – visually, it’s rather well done. The features are pretty good too, arriving regularly to keep the pace high. We’d put the variance in the medium range.

This slot doesn’t exactly re-invent the wheel but it’s entertaining and amusing though. Add a couple of decent features into the mix and Cool Stone Age is a game worth considering. Saying that, I much prefer Playtech’s The Flintstones which has more bonus features.
