Coin Craze: Unlock Reels

Blocker Removal is a feature where parts of the reels are obstructed by inactive 'blocker' symbols at the start of the game, and these blockers are removed through specific in-game actions to progressively expand the game board. The core of this feature is to provide the player with a clear mission of 'unlocking closed spaces to win bigger rewards', and to give the visual fun and sense of achievement of watching the game board grow.

Hold and Respin, or 'Hold & Win', is one of the most popular core bonus game mechanics in modern slots. The essence of this feature, unlike traditional free spins, is to 'Hold' bonus symbols on the reels and 'Respin' the remaining empty spaces to fill up the screen. This system was popularized worldwide through 'Money Train 2's' 'Money Cart Bonus' and is the foundation for numerous developer-specific brand features like Wazdan's 'Hold the Jackpot™' and Playtech's 'Fire Blaze™'.
