About this game

Fire meets frost. The rats melt.

Catalyst Cats is a cute arena roguelite where you only have to move. Your cat wizard casts spells on their own, so all your attention goes to the fun part: building a spell set that chains elemental reactions across the screen.

Hit a foe with fire, then frost, and boom: MELT! Add storm for OVERLOAD, venom for BLIGHTFIRE, and discover all six reactions to unlock the strongest builds.

★ 6 elemental reactions
Melt, Overload, Superconduct, Blightfire, Crystallize and Catalyze. Each one you discover is announced and added to your collection.

★ 16 spells, 40 relics
Merge two identical spells to raise their tier, hold up to six at once and pick relics that turn a good build into a great one.

★ 27 hidden secrets
Secret combos, a signature trick for every cat, relics that awaken when you hold three and relics that fuse into something new. Nobody tells you where they are: you find them by playing.

★ 8 cat wizards
From Mochi the apprentice to Glitch the rainbow void cat, each with starting spells and a passive of their own.

★ 3 arenas, 6 bosses
Moonlit Meadow, Crystal Caverns and the Void Rift, 10 waves each, elites, hordes and bosses with a second phase. Clear them all for Endless mode and six Curse levels.

★ Shop between waves
Reroll, lock, sell and merge. Element Resonance rewards you for building around an element.

★ Short runs, one thumb
About ten minutes per arena. Move with one finger; everything else is automatic.

★ Keep growing
Academy upgrades, daily quests, 39 achievements, a collection book and 14 cosmetic hats.

Free to play. Optional ads give bonus rewards; optional in-app purchases are available. Cosmetic hats have no stat effects.

Play in English, Korean, Japanese, German, French, Spanish or Portuguese.
Cat wizards mix spells, trigger elemental reactions and melt the rat horde!
