TuxMathScrabble is a math version of the classic word game "Scrabble" (Trademark of Hasbro,Inc) which challenges kids to construct compound equations and to consider multiple abstract possibilities. There are four skill levels for practice, from basic addition with small numbers, through multiplication and division with larger numbers. The game can be played by 0, 1 or 2 human players. Player submissions are made by dragging tiles to the gameboard and pressing the "okay" button when ready to be validated. Invalid submissions are thrown-back to the user's tray. Several new features have recently been added, such as the ability to shuffle player tiles in-place, the programatic creation of tiles on-the-fly (as opposed to using images), configurable tile transparency, the ability to use a background image, and the option of configuring the "None" character for either/both players.
