Stack Cats
Read full descriptionHide full description
Every cat has a personality. Find the perfect stack. Cat Stack Club is a cozy cat-stacking puzzle. It looks like a simple "sort the same color together" game — but after a few levels you realize color is only the beginning. Each cat has its own temper and its own rules about who it will sit next to. 8 CAT PERSONALITIES · Chubby Cat — too heavy, only fits at the very bottom · Cat King — wears a crown, refuses to let anyone sit on its head · Sleepy Cat — fast asleep, move another cat to wake it up · Best Friends — linked by hearts, they move together as a pair · Shy Cat — won't be the first one into an empty bed · Likes & Fears — some cats love a color, some are scared of one, and they can't sit next to each other Play at your own pace. No move timers, no pressure for three stars. If you get stuck, hints and a temporary spare bed are there for you. 280 LEVELS ACROSS 7 CHAPTERS Living room → kitchen → garden → bedroom → rooftop. Each chapter unlocks new scenes and new cats, and clearing levels drops furniture so you can decorate your own cat room. 40 CATS TO COLLECT From orange tabbies and tuxedos to ragdolls, Bengals and Sphynx. Every cat is a hand-drawn chibi illustration. Rarity only affects your collection — never the difficulty. COMFY SOUND & FEEL Lazy, relaxing original music, a different cute reaction sound for each cat, and springy squash-and-stretch landing animations. CLEAN AND SIMPLE · Play offline, no login required · Full-screen, distraction-free · 7 languages: 简体中文 / English / 日本語 / 한국어 / Français / Español / Русский · No forced ads — remove them in one purchase Every cat has a personality. Find the perfect stack.
