Game details

What is Slime Stack Merge about?

Slime Stack Merge is a cozy but clever number-merge puzzle. Drop slimes into one of five columns – when two slimes with the same number touch, side by side or stacked, they squish into the next bigger slime. Touch three at once for a TRIPLE that jumps two sizes!
- 40 goal levels: build the target slime before you run out of drops. Bonus stars for high score and few drops.
- Daily Challenge: the same seeded slime sequence for everyone each day – 40 drops, one shot at a high score, +100 coin bonus.
- Endless mode: play until the board overflows and chase your best score.
- Slime skins: earn coins from every game and unlock Kitty, Bunny, Cool Shades, Party Hat, Ninja, Angel, Star Eyes and Wizard slimes.
- Juicy combos, chain reactions, particles and satisfying sounds.
- Short, skippable-in-play tutorial for new players.
