Prism of Gems Online Slot Review

You can win up to 30,000x your wager with the Prism of Gems slot from Play’n GO. This 5-reel, 576 ways to win game sees marble-effect reels under a glass dome, and comes with some exciting gameplay. Cascading reels, splitting symbols, multipliers of up to 343x, and a rewarding free games round can give your bankroll a serious boost at any time.

A default return to players percentage of 96.24% combines with a high volatility. Play this gem on PCs, iOS, Android, or Windows mobile devices at the best online casinos.

How to Play the Prism of Gems Slots Game

The design is quite unusual, with a Victorian style to the huge dome behind the reels. A decorative frame surrounds the 5 reels, and you’ll notice a sixth reel at the top, which spins from right to left. The lower paying card symbols look as if they are engraved onto the marble-style backing, and there’s a variety of bright jewels that return higher prizes when crossing any of the 576 different ways to win.

The standard Play'n GO controls feature here, which is a definite plus, as they are easy to use and offer several customization options, such as Auto and Turbo modes. Scroll along a bar beneath the reels to select a wager from 0.20 to 100.00 per spin, and you are ready to play.

It’s a good idea to review that paytable first, to see how the innovative features, such as splitting symbols, all work. The table also has a full list of how much you win from the different symbols, with the most valuable gem paying out 3x your wager when it lands across all 5 reels. A wild symbol helps out by acting as others if it can complete a winning sequence.

Free Spins & Other Features of the Prism of Gems Slot Machine

The Prism of Gems slot uses a cascading reels mechanism. It removes symbols in a win, and those above drop down to fill the gaps, potentially leading to more wins, and more cascades. The reel at the top of the game is key to unlocking huge win multipliers.

Each time a symbol on this reel is part of a win, a multiplier increases by 1x, and continues to rise throughout any series of cascades to a maximum of 7x. It’s possible to build a vast multiplier of 343x from this feature, but they reset back to 1x once the cascades end.

The symbols on the top reel also split any matching symbols below them. This gives you more ways to win, and any wild symbols will split all others on the reel underneath.

Land 3, 4, or 5 scatter symbols to trigger 10, 15, or 20 free spins. Multipliers don’t reset during the bonus round, so it’s easier to hit that maximum of 7x on each top reel. You can’t retrigger the whole round, but each time the scatter symbol appears in the free spins, it adds 2 extra games to the total.

Prism of Gems Slot Maximum Wins, Average Returns, & Volatility

The vast 30,000x maximum win equals 3,000,000.00 when you play with a stake of 100.00.

Prism of Gems is a highly volatile slot, and there’s an average return to players percentage of 96.24%.
