Pragmatic Play – Gems Bonanza – Free Slot Game

Gems Bonanza is an 8×8 grid slot from that comes with 5 different reels modifiers in the base game. This is a very volatile title with an above average RTP of 96.51% and a 10,000x potential. The 5-level bonus round parades all 5 Reels modifiers like pearls on a string, and each new level gradually increases the win multiplier up to 10x.

On each spin, 64 glowing gems drop down, and you need to form matching clusters of more than 5 to 25 symbols to win. The cascading wins feature gives you plenty of new opportunities on a regular basis, and the various reels modifiers are triggered quite often. This greatly breaks up the drudgery of the base game and makes the overall experience less volatile than it actually is.

The game’s pace is pleasant enough, and it’s set to a soothing synth soundtrack. You can place bets between 20p and £100 per spin on all platforms and devices, and the 5 premium gems pay out between 50x and 1,000x for 25+ in a cluster. Wilds can’t land organically here, but you can look forward to plenty of wilds from 2 of the 5 reels modifiers. Gems Bonanza is a very fun game that also offers solid performance without ever feeling overly brutal or “hard to get”.

Bonus Features in Gems Bonanza

On each spin of the base game, you’ll see up to 4 different colored dots in various configurations on the wall/map behind the symbols. When you land a winning combination over one or more of them, you trigger the corresponding Reels modifiers:

  • Blue dot (Nuclear modifier) – clears all symbols and gives you a new game.
  • Pink dot (Wild gem) – turns all instances of a randomly selected symbol into Wilds.
  • Brown dot (Squares) – gives you identical 2×2 Mega symbols randomly added to the grid.
  • Red dot (Colossal symbols) – a 3×3, 4×4 or 5×5 mega symbol is randomly placed on the grid.
  • Green dot (Lucky Wilds) – gives you 5 to 15 wilds randomly placed on the grid.

You can win more than one modifier at a time, and if so, they will be played in the order specified above.

On the right side you will see a Gold Fever counter, and each fall win fills the counter with liquid gold from the collected symbols. The counter is reset on losing spins, and 114 winning symbols are needed to fill the counter. This triggers the Gold Fever bonus round.

The free spins feature offers 5 levels, and you start with level 1. The multiplier starts at 2x for level 1, and you now get all 5 Reels modifiers in sequential order. You also collect symbols here, and if you fill the meter again, you will move to the next level. You need to collect 116, 120, 125 and 130 symbols to reach level 2, 3, 4 and 5 respectively.

Levels 2 to 5 contain multiplier values of 4x, 6x, 8x and 10x. All 5 modifiers are played on each new level. The bonus round ends when all 5 modifiers have been played and you have not collected the symbols required to advance to the next level. When you reach level 5, the feature will end once the 5 modifiers have been played.

Depending on your jurisdiction, you can buy the Gold Fever progressive bonus round by paying 100 times your bet. It plays out exactly as if it were triggered organically, but UK players cannot use the buy option.

The 200 Spins Gems Bonanza Experience

Grid slots are usually action-packed and exciting, and we were really looking forward to seeing this massive 8×8 setup with gems in action. We actually managed to get to the second level in the bonus round, but rumor has it that it’s quite difficult to get any further. Check out all the highlights from our 200 spins test session in the video below.

Rating Conclusion

Like so many grid slots, Gems Bonanza has that “oddly satisfying” quality that makes you feel comfortable playing inside. There are plenty of base game features to keep you entertained here. However, it’s a bit of an overkill to display the name of each feature in bold in front of the grid every time. No need for such hiccups to interrupt the otherwise nice flow.

The bonus round offers you all 5 features in a row, which is pretty neat, but getting past level 2 is not that easy. Even at this level, you can still get solid payouts, and the 10,000x potential is very solid even for a very volatile game. There may not be anything new to see here. However, all the moving parts have been arranged together in a unique and effective way, resulting in a very decent grid slot experience.
