Ultra Gems

Ultra Gems Review

The ceiling is the thing to understand before anything else. The maximum we have on record is 150x your stake, and published figures elsewhere disagree with each other, so the paytable inside the game is the only number worth acting on. Either way this is nowhere near the four-figure multipliers modern video slots advertise. Ultra Gems is not a game you play hoping for a life-changing spin, and any page telling you otherwise is selling something.

The return is 95%, a little under the mark — most of the 987 slots we list pay back 96% or more. Combined with a low ceiling, that makes this a game for short sessions and small stakes rather than a serious grind.

Two mechanics carry it. The win multiplier triggers when matching mid-range symbols fill the reels, and the gamble round lets you double a win by guessing whether the next card is red or black — lose the call and the win goes with it. On a three-reel game with no free spins, the gamble is where most of the drama actually lives, and it is entirely optional.

One caveat on the numbers: our data records the volatility as moderate, but at least one published review rates it high. On a three-reel classic with a multiplier and a double-or-nothing gamble, high feels closer to how it actually plays. Treat the moderate label with some caution.

If you want the same stripped-back classic feel with a better return, Mystery Joker pays 97% and Fire Joker 96%, both from Play’n GO and both playable free right here.

How to play and how to win

Stakes run from 1.00 to 500 a spin, which is a wide range for a game this simple. All five lines are fixed, so there is nothing to select. Wins pay from the leftmost reel, and matching mid-range symbols across all three reels is what triggers the multiplier. After any win you are offered the gamble: take the win, or call red or black to double it. The gamble is the only real decision in the game, and declining it is a perfectly good strategy.

Ultra Gems RTP

According to Novomatic, Ultra Gems’s RTP is 95.00%. That sits below the 96% most modern slots clear, and Novomatic games often ship in more than one configuration — so check the paytable at whichever casino you play rather than assuming this figure.
