Number Twins - educational game

Number Twins is a free online flash game of the category educational games.

In this game there will be a grid of balls numbered from 1 to 9. You need to match the balls that add up to 10. A pair of balls can only be matched if they can be connected by a line that turns at most twice. If you can match the balls with a star on them, then the other balls will all be sorted by colour and it will be easier to spot the ball pairs. Use the mouse to click the balls to form the pairs. The faster you finish, the higher the score.

A context menu should be shown when right-clicking or, on touch devices, long-pressing in the game. This menu especially allows to play in full screen and control the volume.
