Gems Bonanza Slot R eview

Pragmatic Play’s Gems Bonanza slot is an interesting game that offers decent winning potential. You don’t see many cluster-based slots from this developer, which makes this game a lot different from Pragmatic Play’s other offerings. So, if you’re not typically a fan of their games, this is definitely on that you’ll want to try out.

Highly Volatile

There are only a few of the highlighted spaces on the reels each spin, but it’s not as hard as you would expect to trigger the Spin Features, giving you something to look forward to as you wait for your bigger wins. Still, it is a very highly volatile online slot, so you don’t experience wins all that often. If the volatility were turned down just a little bit, the gameplay would hugely benefit and give you a bit more excitement on each spin.

Exciting Bonus

The Gold Fever feature is great but, again, it’s very difficult to trigger. The Spin Features help to boost your bonus meter charges, but you still do have to wait quite a while before you land any win sequences that will earn you over 114 points. Once you do, though, you’ll can almost always walk away with an impressive payout.

Gems Bonanza Bonus

Even though we have some grips about the game, Gems Bonanza is good fun. With a slightly higher-than-average RTP of 96.55% and a top prize of 10,000x, the game does offer up great gameplay. On top of that, there is such a wide variety of bonuses on offer, which is something that is pretty rare in slots games.
