Spin Spell is a physics based 3D mobile game that motivates children to learn to spell while having fun and improving their hand/eye coordination. Children learn to spell by navigating a variety of 3D spelling mazes. Points and achievements are awarded based on the sequential collection of letters to correctly spell a word, the speed by which the letters are collected and the number of correct letters collected in a streak. Points are never subtracted from the score but bonus streaks are reset when an incorrect letter is hit and/or when the game timer expires.
