Jackpot Gem Rush is a Mascot Gaming slot where the coin action does not wait for the bonus rounds. When the Collect coin lands, it scoops up their values in view, paying in the base game as well as during free spins, long before any feature has fully taken shape. Around it are the two main rounds: a coin-collect Hold and Win with Mini, Major and Grand jackpots, plus a 10-spin free-spins round with a wheel that can boost a winning spin even further. You can try it all for free in the demo before playing for real money.
The grid is built around coins, with five connected features feeding into the same treasure-pot rhythm.
Land six or more coin symbols anywhere to start the round. Every coin locks in place, and you get three respins with only the empty cells turning; the current count is shown to the right of the reels.
Each new coin resets the count to three, so the round keeps going while coins continue to land, ending only when no respins remain or the grid is full.
Once it stops, every coin on the board pays as one total, and filling all 15 positions awards the Grand on top.
The Collect is a red coin that sweeps up the others. When it lands with coin values, it adds every one to the win, and it does this in both regular play and the free spins, not just once a round is running.
A jackpot coin caught with a Collect pays out at once. It’s the piece that lets the coins matter away from the bonus.
Three or more crown scatters award 10 free spins, and that count stays fixed no matter how many land. Hit 3, 4 or 5 crowns, and you still play 10 spins.
Extra scatters pay a bigger coin rather than adding more spins. The round runs at the triggering stake and can retrigger if the scatters return.
Any winning spin can be pushed on the Risk Wheel, the gamble half of the Risk’n’Buy menu. It shows multiplier segments that lift the win, losing segments that take it away, and arrows that move you inward to a better-paying ring, as high as 1000x the bet.
That menu also sells the two rounds outright. The Hold and Win runs 75x and drops you in with six coins held from the off, while the free spins are 150x for the 10 they normally give. Neither buy works in Autoplay, and each plays at the stake set when you press the button.
Wins pay on 10 fixed paylines, and only the highest on each line counts, wherever along it the matching symbols land. Bets go as low as £0.10 and up to £10.00, and we played £1.00 a spin. Gem and royal symbols pay those lines.
The coins are a separate currency that sits outside the paylines, and each has a set cash value, coming into play only when a Collect gathers them or six or more begin the round.
The free-spins round and the coin round sit on top of standard play, and you can try both, with the wheel and the two buys, in free play.

Jackpot Gem Rush earns its score on how much of it stays live at once. Two bonus routes, a coin round and a free-spins round, and a Collect that pays in ordinary spins too, keep the coin action going across the game, feature or no feature. The bigger rounds come when the coin round fills out and the Grand drops on top of the values there. The Collect is what ties the coin play together, one idea at work in a plain spin and the bonus alike.
Two separate bonus rounds give more to reach for than one, the Hold and Win and the free spins both open in play or bought outright. The wheel puts a gamble on any winning spin, and the coins hold real value in their own right.
The game takes place in a palace chamber, with stone arches framing a hoard of loose gems and a chest of gold spilling out to one side. The gold-lined reels stack coins along their top edge as they land, a purely visual flourish rather than anything that banks value. A flute-led score gives the game a regal tone, while the free spins carry the same hall into dusk as the music shifts to harp. Wins are shown clearly below the reels, with the running total in white and each spin’s individual win in yellow beneath it, making the wins easy to follow.
The cap is the real limit, a 3,500x top that sits low for a slot this volatile. The scatters are the other letdown, since a 4- or 5-scatter hit brings no more spins than 3 does, just one larger coin.
The Hold and Win is the core of the game, and a 75x buy in our review put it to the test. It built fast and stalled one coin shy of the Grand. A red Collect arrived late, worth £41.40, and swept the lot. A £75.00 buy came back as £95.80, in profit even though the coins never covered all 15, and it was easy to see how a complete set would have added up.
The free spins keep every coin rule intact, so a Collect can still rake them in while they run. Ours did the scoring alone, as 3 scatters opened 10 spins that returned £258.60 with no wheel in it, the coins piling up while the reels worked their lines beneath. That was well over the 150x a bought free-spins round would have cost.
The wheel is where a win can really climb. Land one, and the Risk icon under the spin button lights up in yellow. Click it to stake your current win, then either cash out your total or you can restake it if the gamble lands. Ours turned a £149.70 free-spins win into £449.10 on a single x3. One mega win in that run paid £82.50, and the total sat just short of the game’s 150x buy price before we gambled our winnings.
What this game will not hand you is a huge top prize. The return is 96.01%, or 96.13% on the buy-and-wheel side, volatility is High, and wins are capped at 3,500x. The three fixed jackpots are Grand 2,000x, Major 50x and Mini 10x, and because even the Grand requires all 15 coin positions to fill, the headline figure feels smaller than the treasure theme suggests.
