Blinkadoo can be played by one person against the Avatar, or by two people connected with iPhones. It is simple enough to be enjoyed by autistic persons that have the cognitive ability to play a game as difficult as tic-tac-toe. Individuals with special abilities can also play the game at a higher blink settings in which case the device can be used as a nonlocal coincidence counter.
A player wins by receiving nonlocal signals to make correct selections. The computer will randomly deal a symbol to each player. Each player then selects whether or not both players were assigned the same symbol or different symbols. Each trial is called a blink. The default setting is 10 blinks, but can be modified using the -/+ buttons. After the last blink, the final results are displayed.
