Browser math games that start in one click and remember progress on the device, with no account and no leaderboard chasing.

• Quiz Race

  Answer to move. Every correct answer moves you along the track, and the Professor is jogging steadily towards the finish whether you answer or not.

• Factors Game

  Your number falls down a board of numbers. Land on one of its factors and it divides; land on anything else and it adds. Get as close to 1 as you can, in as few moves as you can.

• Tangram

  The oldest shape puzzle there is. Drag the seven pieces, turn them and flip them, and see what you can build — a square, a cat, a boat, or something nobody has made before.
