I co-designed a math facts game that I have released to the public domain. MathBOTs is a rigorous, artificially-intelligent 3D, arcade-style K-6 math fact drill program for PC-compatibles. Repel invading math facts from the front view port of your spaceship. Planets warp past you as you fly to a sector where math facts zoom towards you to be repelled by your answers. MathBOTs runs from DOS or Windows (including Windows 95 and 98, 98se; and XP). It uses VGA graphics, Sound Blaster music and sound effects, 130 developmentally-sequenced missions (+ – x / and Custom), frequent review of missed facts, adjustable speeds, an animated hint mode, memory tricks, progress charting/graphing, and a custom drill editor. http://www.deankindig.com/MathBOTs/
