Welcome to Catculus: Math Puzzle Game, the charming and mentally stimulating online puzzle that blends arithmetic practice, strategic thinking, and memory training into one endlessly fun experience. Made for players of all ages who love a gentle yet rewarding mental workout, this game puts a fresh, cat-themed twist on classic number puzzles, helping you sharpen cognitive skills while you play without feeling like a boring study task. Whether you’re looking for a quick 5-minute brain break between tasks, a fun way for kids to practice addition skills, or a casual challenge to keep your mind sharp as you unwind, Catculus fits the bill perfectly. The core loop is easy to pick up, but the challenge ramps up at a steady pace so you never get bored or feel overwhelmed.

Every round of Catculus starts with a clear target sum shown at the top of the screen, plus a board of numbered tiles you can select. Your goal is to pick a combination of tiles that add up exactly to the target sum, no more, no less. Go over the target, and you’ll get a penalty: too many penalties will end your run. As you progress, mischievous black cats will pop up randomly to cover some tiles, so you’ll need to rely on your memory to remember the values of hidden tiles to keep hitting your target sums. You can also collect special power-ups as you play to reveal hidden tiles, freeze the cats so they don’t cover more tiles, or get a helpful hint when you’re stuck.

Cute cat-themed design, progressive difficulty, useful strategic power-ups.

Catculus is a wonderful, family-friendly brain game that makes practicing math and memory skills feel like play. Give it a try today to see how high you can score!
