Free Spin
End-Condition Free Spin
A type of free spins with no set number of spins, which instead ends when all of a specific 'end symbol' are collected.
Persistent Free Spin Grid
The game grid's cleared state remains throughout the free spins.
Persistent Free Spin Grid is a unique bonus game feature where the destruction or modification of the game grid is maintained throughout the entire free spins round.
This mechanic ensures that any cleared blocks, expanded rows, or empty positions do not reset between individual spins.
The core of this feature is to provide a continuous sense of progression and accumulating potential, as the player's actions in one spin directly influence the setup for subsequent spins.
