Halloween monsters merge drops you into a falling-piece puzzle where the goal is to collide identical monsters, grow your collection, and climb to first place on the leaderboard. The playing field fills from the bottom up, and the pressure builds as you work to keep every monster below the top lane. A large green sphere with a pink brain-like texture on its top and visible white teeth appears across several scenes in the game. In one moment, a vertical dashed white line extends downward from a purple character sphere, marking where the next piece will land.
A monster is shown above the playing field, ready to fall. Drop it down and aim to land it on an identical monster — when two matching monsters touch, they merge into a single larger one. Each successful connection earns coins, and newer monsters yield more points per merge, giving a real path to beating your personal record.
Coins collected from merges can be spent in the store to unlock new monsters. The main goal is to unlock every monster in the game and reach the top of the leaderboard. If the field fills completely and monsters cross the top line, the session ends.
