Base Game

This game features a 7×7 reel with a cluster pay system.

When five or more adjacent identical symbols align vertically or horizontally on the reels, they form a winning combination and are removed from the game screen.

New symbols then fall from above to fill the empty spaces.

During a spin, the meter fills up based on the number of winning symbols.

The meter has five levels, and the number of dice that can be rolled in the DOKI DOKI DICE feature increases according to the level of the filled meter.

Add Wild Feature

When a winning combination includes a WILD symbol and the symbols are removed, there is a chance for a new WILD symbol to appear in one of the empty spaces. This new WILD symbol may also come with a multiplier.

Doki Doki Dice Feature

If the meter can be filled by one or more levels within a spin, the DOKI DOKI DICE feature will activate when no further payouts are generated.

After a dice roll, the total number rolled will determine the number of WILD symbols that appear in random positions on the reels.

These WILD symbols will have multipliers attached.

The possible multipliers are x2, x3, x4, x5, x6, x7, x8, x9, and x10.

The number of dice that can be rolled changes according to the level of the filled meter.

During FREE SPINS, the number of dice that can be rolled increases.

However, if the following rules are not met, the appearance of WILD symbols will end at that point.

• A winning symbol must always remain on the reels.
• WILD symbols with multipliers and SCATTER symbols will not have WILD symbols appear on top of them.

Free Spins

In the BASE GAME, if three or more SCATTER symbols land, FREE SPINS are triggered.

When three SCATTER symbols align, it triggers 8 FREE SPINS.

When four SCATTER symbols align, it triggers 10 FREE SPINS.

When five SCATTER symbols align, it triggers 12 FREE SPINS.

The number of dice that can be rolled in the DOKI DOKI DICE feature during FREE SPINS depends on the number of SCATTER symbols that landed.

If three or more SCATTER symbols land during FREE SPINS, additional FREE SPINS are awarded.

When three SCATTER symbols land, 8 additional FREE SPINS are awarded.

When four SCATTER symbols land, 10 additional FREE SPINS are awarded.

When five SCATTER symbols land, 12 additional FREE SPINS are awarded.

During FREE SPINS, the number of winning symbols required to fill the meter is different from the BASE GAME.

Max Potential Win

The maximum potential win in any given spin, or total win during the FREE SPINS is 5000x BET.

When the maximum potential payout is reached, the spin or FREE SPINS are immediately concluded and the payout of 5000x BET is awarded.
