Base 20 Desktop controls: Left and right arrow keys move to previous and next. Press space to go to a random number coin from 0 to 100. (In vigesimal.) I might make higher bases of number coins in the future but in a completely new and different format. Left and right arrows move to previous and next. Left and right arrows marked with 'x10' move in tens. Tap on my watermark to go to a random number 0 to 499. Tap on the background to change to dark mode.
