Free addition games
Where early math confidence starts. Kids build addition facts from the ground up in a fast, friendly arcade — free, no sign-up, no ads.
Starts gentle, grows with them
The ladder opens with the easiest wins — the +0 and +1 facts — so a young child feels successful right away. From there it works through +2, +3, and on up, then into adding within 10 and within 20. Each step focuses on one family of facts at a time instead of a random jumble, which is what makes the facts actually stick.
Games that drill addition
Turbo Math
Type each sum to send your race car flying forward.
Math Invaders
Blast the alien holding the correct answer to an addition problem.
Fluency that lasts
Facts count as mastered only when a child answers fast and correct, so play builds automatic recall — and about one problem in four revisits older facts so they don't fade. Speed targets are relaxed for the youngest players. Best for roughly pre-K through grade 2.
