During base game, instead of always having fixed height in the spin (3-3-3-3-3), the reel height is random for each spin.
Every reel has a reel multiplier assigned to it, which increments every time there is a symbol win (+1 for every symbol win). During base game, whenever a reel is at maximum height the multiplier multiplies wins which were happening on unlocked reel. During free spins, whenever a reel is maximum height, the multiplier over the reel is transferred and added to the global multiplier, which will now be applied on any future wins. The reel multiplier is not active unless the reel is fully expanded to its full height. During base game maximum reel height is: 7 symbols tall During free spins maximum reel height is: 8 symbols tall
When a win combination appears, the winning symbols are replaced by new symbols and the reel extends. Symbols will cascade from the top, instead of appearing in the cells of the winning symbols.
Symbols can pop by random amount ranging from 1 to 4.
The player can get up to 3 additional free spins when special bomb symbol drops. Special free spins bomb symbol instantly unlocks the reel which it landed on to its full height and activates the reel multiplier.
Landing 3, 4 or 5 bonus symbols during base game will trigger the free spins mode There are 3 Free Spins Modes:
Free spins end when the counter reaches 0 and the last spin is played. Bonus symbol appears only in base game.
