FunBrain — A long-running educational site with math games covering arithmetic, fractions, and basic algebra. Good for middle school and younger.
Prodigy Math — A curriculum-aligned RPG where you answer math questions to progress through the game. Popular in classrooms, free to play.
Mathigon — Interactive lessons and puzzles covering everything from arithmetic to topology. More educational than game-like, but very well done.
