Features

Special Symbols

The wild symbol substitutes for all symbols in the paytable.

FS Scatter symbols appear in both the main game and the bonus game. They can only appear on reels 1, 3, and 5, with a maximum of one FS Scatter symbol per reel.

Only one Windmill symbol can appear naturally per spin. The Windmill feature can create multiple Windmill symbols when activated.

Multiplier symbols appear only during the Windmill feature.

The Shutter symbol only appears during the Windmill function.

Windmill Feature

The Windmill feature is activated when the Windmill symbol appears during the initial spin and there are highlighted positions created by wins. The Windmill symbol serves only to activate the feature and does not award wins. Windmill symbols do not appear during cascades. All winning symbols from the initial spin are marked with a frame, as are any additional wins awarded during cascades.

Once all cascades are completed and winnings are paid out, the Windmill feature begins. New Windmill symbols appear in all marked positions. Each Windmill symbol, including the activating Windmill symbol, reveals a bet multiplier symbol with a random value of 1x, 2x, 3x, 4x, 5x, 10x, 20x, 50x, or 100x, or transforms into a Shutter symbol. Revealed multiplier values ​​become the feature’s base bet multipliers. If any Windmill symbol reveals a Shutter symbol, it is revealed and reveals a bet multiplier boost.

Add symbol

When the Shutter symbol opens, it reveals an Add symbol with a bet multiplier value. This value is added to all existing bet multipliers of each Windmill symbol and previously revealed Shutter symbols. The value remains displayed on the Shutter symbol.

Collect Symbol

The Shutter symbol reveals a Collect symbol with a bet multiplier value. It collects all current bet multipliers of each Windmill symbol and revealed Shutter symbols, sums them, and adds the total to its own multiplier. All collected bet multipliers remain unchanged on their respective symbols.

Add + Collect

When a Shutter symbol reveals an Add + Collect with a bet multiplier value, it first adds its value to all existing bet multipliers, then collects the updated multiplier values ​​of each Windmill symbol and revealed Shutter symbols and adds the total to its own multiplier, while all collected bet multipliers remain unchanged.

Collect + Add

The Shutter symbol reveals Collect + Add with a bet multiplier value. First, it collects the values ​​of all current multipliers and adds the total result to its own multiplier, while all collected bet multipliers remain unchanged on their symbols. Then, it adds its value to all existing bet multipliers, updating each bet multiplier on the symbols.

Any Shutter symbol can reveal a random bet multiplier of 1x, 2x, 3x, 4x, 5x, 10x, 20x, 50x, or 100x. When multiple Shutter symbols appear, they are activated one at a time, processed reel by reel from left to right, and within each reel, from top to bottom. If a Shutter symbol reveals when there are no other multipliers to add or collect, it retains only its own bet multiplier. After all Shutter symbols have revealed their results, all bet multipliers visible on the screen are summed and multiplied by the bet to determine the final feature win. The feature then ends.

Zeibekiko Bonus

Land 3 FS Scatter symbols in the base game to activate the Zeibekiko Bonus and win 10 free spins. The same mechanics apply as in the base game, with one key improvement:

During each free spin, all winning symbol positions are marked, even if the Windmill symbol doesn’t appear. These marked positions are saved on the reels and carried over from spin to spin as long as wins continue. As soon as the Windmill symbol lands while at least one marked position is present, the Windmill feature is activated. After the feature ends and the payouts are complete, the grid resets, and the marking process begins again on the next free spin.
During the Zeibekiko Bonus, landing additional FS Scatter symbols awards additional spins:

• Locating 2 FS Scatter symbols awards +2 free spins
• Locating 3 FS Scatter symbols awards +4 free spins

Paylines

The winning combination requirements stated in the main game also apply during bonus features or free spins, unless otherwise stated. Each bet entitles you to all winning combinations, unless otherwise stated. You win if identical symbols appear on one of the following specified lines on adjacent reels from left to right, starting with the leftmost reel. The number of possible lines in this game is 14. The number of each symbol required for a win is specified in the paytable.

After each win, the symbols in the winning combination are removed and new ones appear. This continues until there are no more new wins left on the reels.
