use turbo mode draw in the squares then push space for it to guess the number you drew (currently only 1-4) If it's wrong, type the correct number (push "1" or "2") There's no cloud saving so you can just export the lists then import them if you want
if you don't have good mouse control (like me), get a large surface as a mousepad and grab the mouse with both hands It can be trained (manually) more and eventually guess better. The more samples = the more accuracy! 3 is the hardest for it to guess due to its similarities to "2"
