When matching combinations are formed and winning symbols disappear, the remaining symbols move down. Then, new symbols drop from above to fill the empty spaces. The process is repeated within one spin until no more winning combinations are formed.

Wild substitutes for any other symbol, and it is not affected by four additional features (Wild Blast, Smash, X-lines and Clone).

When 4 identical symbols form a square next to each other, they become a single 2x2 Big symbol. This Big symbol doubles the payout for the winning combination it's a part of. If several Big symbols are involved in a combination, their multipliers are summed up and boost the final payout.

A Big symbol can split into 4 regular symbols during the refill. This feature doesn't apply to Wild symbols.

After every spin, randomly chosen low symbols start shining. If these symbols form a winning combination, they disappear, and 2 Wild symbols appear in their place. 

If more than one winning combination is formed this way, the feature applies once to all combinations on the screen. Wilds lasts until the next spin, and the shining symbols do not change during the refill.

If a spin does not result in a win, a random number of symbols can turn into Wild symbols. In this case, the win amount is recalculated. This feature can trigger a Big symbol.

Every symbol in winning combos during one spin reduces the Progress Bar by 1 point out of 100. As soon as every 25 points decrease the Progress Bar, an additional random feature (Wild Blast, Smash, X-lines, or Clone) is triggered. 

When the Progress Bar reaches zero, it activates the Pot feature.

This feature may activate when the Progress Bar drops by 25 points. Wild Blast turns 3 to 6 symbols into Wilds, and each Wild destroys four neighboring symbols (above, below, to the right, and left), but it doesn't award any winnings.

This feature may activate when the Progress Bar drops by 25 points. Smash eliminates all low symbols without awarding any win.

This feature may activate when the Progress Bar drops by 25 points. X-lines places a Wild symbol in the center of the field, and all symbols on the diagonal of the Wild turn into random identical symbols. If any of the diagonal symbols are Wilds, they stay as Wilds.

This feature may activate when the Progress Bar drops by 25 points. Promotion turns a randomly chosen symbol and all its copies into another identical symbol.

The feature activates when the Progress Bar hits zero, and a 3x3 Wild symbol appears. In the second refill, the 3x3 Wild splits into two 2x2 Wild symbols, and in the third refill, it divides into nine separate Wild symbols. Any winning Wilds disappear.

Players can trigger the Pot feature by buying it at a price pictured on the Buy Bonus button. Its price will be automatically adjusted if a player changes the bet.
