Deca: Merge to 10 is a fast-paced number puzzle game where you drop jelly blocks into a grid and combine matching values. When two identical numbers touch, they merge into the next number, letting you create chains and keep space available for new blocks. Play Classic Mode against the clock as you race to create tile 10, or continue climbing through increasingly difficult layers in Endless Mode. Smooth animations, satisfying merge effects, and simple controls make every run easy to start and challenging to master. Play the Deca: Merge to 10 game at Y8 now.
