2 Million B.C.'s Prehistoric Bonus Round

How 2 Million B.C. Plays

This is a medium-volatility five-reel game, which in plain terms means the swings sit between the calm rhythm of a low-volatility grid and the bigger, spikier runs of a high-volatility one. The scenery is built entirely around an adventure and prehistoric setting, so the reels lean into a caveman camp with dinosaurs roaming somewhere close by rather than any modern city or fantasy backdrop. I've spent enough time working a casino floor and later reviewing studio catalogues to know Betsoft usually favours this kind of cinematic, story-forward reel design over flashy, complicated math models — you can read more about how I check these details on the About page.

The Bonus Round Here, Not a Bonus Buy

2 Million B.C. carries a confirmed bonus round: a dedicated feature stage that sits apart from the base game rather than a purchase option. That's worth flagging plainly, because not every prehistoric-themed slot in this library works the same way — this one gives you a proper feature stage to reach, not a button that lets you buy straight into it.

Where the RTP Sits

The confirmed return to player is 91.94%, and that's below the 95.85% median across the slots covered on this site. It's not a red flag on its own — RTP is a long-run average, not a promise for any single session — but it's the kind of number I'd want a player to see clearly rather than bury in fine print before they decide where to spend their bankroll.

Planning a Session Around a Mid-Paced Slot

With medium volatility, I like to split a session bankroll into a decent number of smaller bets rather than a few large ones, since the pace here isn't built for quick, frequent hits the way a low-volatility grid is. Giving the reels more spins to work with simply means you're not judging the whole game off the first few rounds before that bonus stage has had a real chance to show up.

If you want another medium-volatility bonus round without leaving that pace, Big Money Frenzy runs a similarly measured rhythm from Blueprint Gaming, dressed in a gold, high-life theme instead of cavemen and dinosaurs. Both sit on the calmer half of this library's bonus-round lineup, which you can browse in full on the Here2Win Casino best games hub.
