About this game

Twin Shapes is about turning things in your head. Each round shows two bendy shapes built from five to seven cubes. They are always the same set of cubes, joined the same way, but sometimes the right one is a mirror image, like a left glove next to a right glove. No amount of turning makes a mirror image match.

Every shape in the game is checked against all twenty-four ways a cube can be turned, so it never matches its own mirror image. That means there is always exactly one right answer.

Try finding one easy feature first, such as the end of a long arm, in both shapes. Then follow the cubes from there and see whether the next bend goes the same way. Dragging turns both shapes by the same amount, so it does not change the answer.

After each answer, the right shape slowly turns to face the same way as the left one, which makes the difference easy to see. Your score is the number of right answers out of twelve, with your total time shown too. Your best score is saved in this browser.
