Theme and Graphics

4 Supershiny Diamonds slot keeps a retro fruit-machine look with a modern finish. The 7, BAR/Bell, watermelon, grapes, orange, lemon, plum and cherry symbols sit on a dark reel background, styled like a classic arcade cabinet.

Bonus Game with Diamond Features

Any Multi, Charge or Collect Diamond can trigger the Bonus Game when it lands on the 5x3 grid during the base game. The matching feature goes active right away. More than one Feature Diamond can appear on the same spin. Each one activates its own feature at once.

The Bonus Game opens with 3 respins on the counter. Every new Diamond symbol, of any type, resets the respin counter back to 3 during those respins. That reset rule decides how long the round can run.

Each active Feature Diamond, shown above the grid, keeps adding ordinary Diamond symbols to the reels. The total stops at 6 per Feature Diamond. Once placed, these sticky Diamond symbols stay locked on the grid for the rest of the collection round. Regular Diamonds carry a value of 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x or 12x of the total bet. That value gets picked at random each time one lands.

The round ends once the respins run out or the grid fills completely. Every Diamond value on the screen then gets added together and paid straight into the Total Win.

The Extra Feature Symbol converts into a random Feature Diamond. That Diamond either activates a feature that wasn't running yet or reinforces an active one by adding another Feature Diamond to the grid.

Jackpot Diamonds (Grand, Major, Minor, Mini) can also drop in during the Bonus Game. Major, Minor and Mini pay out the moment their symbol appears on the grid, while Grand needs 15 filled cells before it activates.

Super Bonus Game

A Super Diamond can only land during the base game, never inside the Bonus Game itself. When one triggers the round, the reels expand from a 5x3 grid to a full 5x5 field. One empty row opens above and one below. Every Diamond symbol from the trigger spin stays exactly where it landed.

The active Super Diamond, positioned above the expanded grid, keeps adding random Multi, Charge, Collect or plain Diamond symbols until the total reaches 6 symbols. That's the same fill rule as the standard Bonus Game, just running across a bigger field. The Super Diamond itself carries a random value of 7x, 8x, 9x or 10x of the total bet in this round.

Filling all 25 cells of the expanded grid pays the Super Jackpot: 10,000x the total bet. Only that fixed jackpot value goes to the Total Win at that point.

Diamond Features

Multi, Charge and Collect are the three Feature Diamonds that appear during the Bonus Game and Super Bonus Game. Each one changes how symbol values build up on the grid. The differences show up in the math behind the Total Win for each feature.

Multi Feature

Every Multi Diamond that lands during the round places x2, x3 and x5 multipliers on three empty grid cells. Once free cells run out, new multipliers stack directly onto cells that already carry one instead of finding open space. The values on those cells then add together.

After placing its multipliers, the Multi Diamond itself gets a random value between 2x and 10x of the total bet. Those multipliers only apply at the very end of the round, once every symbol value on the grid gets multiplied before the final sum. The Multi Feature effect stays hidden until that last calculation.

Charge Feature

Every Charge Diamond that lands opens 6 extra cells, each one filling with a random Diamond or Jackpot Diamond symbol. Every value revealed in those cells adds directly to the Charge Diamond's own total. Charge is the only one of the three features able to pull a Jackpot symbol straight into its own sum. The other two leave Jackpot symbols to land on the grid separately.

Collect Feature

Collect carries the highest single-hit potential of the three features. Every Collect Diamond that lands adds up the value of every Diamond symbol already sitting on the grid. It folds that total into its own value.

Multipliers apply to Bonus, Jackpot and Super Diamond values before Collect gathers them, so the order those multipliers land in changes the final sum.

4 Supershiny Diamonds Paytable

Payouts run across 5 fixed lines, read left to right, with only the highest win per line counted. All paytable figures here use a $1 stake as their base.

Feature Buy & Extra Bet

Buy Bonus Game skips the wait and drops the player straight into the feature for 100x the total bet.

Extra Bet works differently: it's a stake modifier, not a feature purchase. Paying 1.5x on top of the total bet raises the odds of triggering the Bonus Game on any regular spin. That option also shifts the game's RTP from the base 95.67% down to 95.54% while it stays active.

RTP & Volatility

4 Supershiny Diamonds Hold and Win runs at 95.67% RTP in standard mode, dropping to 95.54% once Extra Bet stays active.

Volatility runs high: the largest sums concentrate in the Super Bonus Game and in the jackpot chain, especially the jump from Grand to Super Jackpot.

The 15,000x ceiling comes with that same swing built in. Budget enough spins to survive a run of Bonus Game rounds that pay little before a Super Bonus Game finally lands.
