A feature where specific symbols are collected during a set number of spins, then released all at once on the final spin to create a big win.

Symbol Release is a unique structure where a bonus round, typically free spins, proceeds with a clear flow of 'Phase 1: Collection' and 'Phase 2: Release'.

The method involves the player collecting as many specific symbols as possible during a set number of spins, and then receiving all the collected symbols back onto the reels at once on the final spin to create a massive win.

The core of this feature is to provide the fun of a 'build-up', where power is gradually accumulated for one explosive climax, rather than each spin being an independent event.
