Chaotic
Arithmetic
Fast, friendly mental-maths drills. Race the clock through times tables and mixed operations, build up streaks, and watch your accuracy climb. Built to make practice feel like a game — great for kids, and surprisingly moreish for grown-ups.
Maths practice that doesn't feel like homework
Chaotic Arithmetic turns mental maths into a quick, punchy game. Questions come at you against the clock; answer fast and accurately to keep your streak alive and push your score. It starts with times tables and opens out into mixed operations as you warm up.
It's designed first for kids building confidence with numbers — short rounds, clear feedback, and a satisfying climb in accuracy — but it scales up enough to keep adults honest too. It's currently in open beta with free guest access, so you can jump straight in and play.
