Sumon

Sumon (formerly, MathMayhem) is an increasingly paced game with the sole objective of entertain (i.e. improving your adding capabilities). Score more points by using more bricks to sum up the proposed number. Use further bricks to enable multipliers. Update (5 April 2011): Sumon is now available in WebGL at http://labs.hyperandroid.com/sumon-webgl . Check it out!
