Catalyst Cats: Spell Roguelite

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 kinds of reactions to unlock the strongest builds.

★ All kinds of elemental reactions

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

★ All kinds of spells and 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.

★ 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.

★ All kinds of cat wizards

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

★ Arenas and bosses

From Moonlit Meadow through the Crystal Caverns to the Void Rift, facing elites, hordes and bosses with a second phase. Clear them all for Endless mode, and raise the stakes with 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, achievements, a collection book and 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.
