Cluster Pays

5 or more identical symbols on the field, connected to each other vertically or horizontally, form a winning combination. Several clusters can fall out at the same time, and all of them will also be winning. A cluster cannot consist only of Wild symbols.

Shrink Shift Clusters

As winning symbols disappear from the field, new smaller symbols fill the empty spaces, creating more clusters that can lead to multiple wins in a single spin. The cascades continue until no more wins fall out.

Wild Scatter

Each time a Wild Scatter falls in the main game, it charges the Scatter Collector, accumulating Scatter symbols during the spin. If at least 5 Wild Scatter symbols are collected during a spin, the player gets 5 free spins. For each additional Scatter, the player gets +1 spin. The Scatter collector is reset at the end of each spin or when free spins are activated.

Free spins

Free spins start on an 8×8 field, which can expand to 16×16. Free spins are played with the same bet as the round that triggered them. The free spins feature a progressive multiplier, accumulating values with Wild Multiplier symbols throughout the bonus game. Each free spin is guaranteed to have at least 1 Wild Multiplier symbol, which charges the progressive multiplier when it hits a winning cluster.

Free spins are restarted at certain multiplier values. Each time the progressive multiplier reaches x7, x10, x50, x100, x250 and x500, additional spins are awarded as follows:

• x7 multiplier gives +1 extra spin;
• Multipliers x10, x50, x100, x250 and x500 give +2 extra spins each.

If the value of the multiplier in the main game activated additional free spins, they go into the bonus game. The progressive multiplier is reset at the end of the free spins. Wild Scatter symbols are not present in the free spins.

Mystery Box

The secret symbol can appear randomly during the game and transform into any regular symbol present on the field. All symbols matching the revealed secret symbol are transformed into higher symbols. The feature does not guarantee a win, but increases the probability of forming new winning clusters.

Random Wild

During the feature, up to 16 regular Wild and Wild Multiplier symbols randomly fall on the field, depending on the size of the playing field. Random Wild symbols can fall at any moment of the game. The feature does not guarantee a win, but increases the probability of forming new winning clusters.

Reshuffle

The Reshuffle feature can be activated at near-maximum field size after a winning spin in both the main game and the bonus game, but only once per spin. If there are large symbols on the field, they are broken into smaller ones during the feature. At the same time, all empty spaces are filled with random symbols, except Wild Scatter and Mystery Box. Once the playing field is filled, all symbols are shuffled. The feature does not guarantee a win, but increases the probability of forming new winning clusters.

Multiplier

The game uses a progressive multiplier that accumulates values using Wild Multiplier symbols. Each time a Wild Multiplier falls in a winning cluster, it charges the progressive multiplier, increasing its value for all subsequent wins in that spin. The multiplier progresses through the following values: x1, x2, x3, x4, x5, x6, x7, x8, x9, x10, x15, x20, x25, x30, x35, x40, x45, x50, x60, x70, x80, x80, x90, x100, x125, x150, x175, x200, x225, x250, x275, x300, x350, x400, x500. When the bonus game is triggered, the current multiplier value from the main game is transferred to the free spins. The progressive multiplier is reset at the end of each spin in the main game.
