Betsoft has taken us back in time for its 2 Million B.C. slot game, which is available at a range of online casino sites.
In 2 Million B.C. players head into the jungle for a slot that features a caveman as the main character, popping up on the right-hand side of the reels.
The five-reel slot has a maximum of 30 payline, which might be less than games such as Megaways slots but is still more than a lot of games have to offer.
This slot has been around for about 10 years, so plenty of newer games have been released since then, but with 2 Million B.C. being set so long ago it does not feel dated at all.
With low volatility, players who pick 2 Million B.C. can expect to receive regular payouts here.
For all the details about playing 2 Million B.C. at online casino sites, check out our full review.
As with a lot of online slots these days, 2 Million B.C. works on a coin system. This means that players need to decide how many coins they want to spend on each spin of the reels.
The 2 Million B.C. stake selection is at the bottom of the screen. There is also flexibility in the game as players can decide how many of the paylines they want to have active, up to 30.
A spin button can be found towards the right-hand corner, next to a button to bet max for any high rollers who want to give themselves a chance to scoop the largest wins on this game.
Symbols like jewels, rocks and a sabre-toothed tiger are among the icons that players can expect to see popping up on the reels when they play this Betsoft title at online casinos.
There is no Wild symbol, but a fire symbol is the scatter and can award free spins on the game.
One of the fun things about playing 2 Million B.C. is that the caveman character on the right of the reels will do a celebration dance after a winning spin.
2 Million B.C. is quite an old slot, having been released back in 2011. It is therefore a bit surprising that Betsoft has a lot of extra bonus features, as well as the fine 3D visuals.
No Wild symbol will be a blow for a lot of people, but free spins can be triggered by the fire scatter. When three of these pop up, players will enter the game's free spins bonus round.
The good news is that more free spins can be earned during the bonus game if more fire scatters pop up, so the round can continue for quite some time.
A second bonus game that has been included in 2 Million B.C. by Betsoft is triggered when three of the acorn symbols appear on the game's reels. In this bonus round, 2 Million B.C. players help the caveman hunt down a sabre-toothed tiger.
The game's diamond symbol also triggers a further bonus round in which the user has to aid the caveman in his attempts to take a jewel from the sabre-toothed tiger. With even some modern slots only having one extra feature, Betsoft has impressed with its depth in 2 Million B.C.
2 Million B.C. has plenty of bonus features to keep people entertained, but the top prizes are not particularly high on the game. Low variance also makes it harder to scoop substantial wins and this is coupled with a very unimpressive RTP of just under 92 per cent. 2 Million B.C. is therefore a long way from being one of the best value games at online casinos. Though it can be fun for a few spins of the reels, the many modern alternatives are likely to be more popular.
