Special Spin
Bet Chance
A unique "second chance" feature triggered by a low player balance, offering a mini-game to win an additional full game spin.
Reel Lock
Take the chance when it comes
Reel Lock is a highly strategic feature that allows the player to select and 'lock' desired reels for an extra cost after a spin is completed.
The locked reels are held for the next spin, while the remaining unlocked reels spin again.
The core of this feature is to provide an active playing experience where the player directly intervenes in the outcome of the next spin, going beyond passively waiting for results, to turn a near-miss into a success or create a greater opportunity.
