Brain Games › Lights Out

Practices: Planning ahead and noticing that order doesn't matter, only which switches you use. Puzzles are made fresh by the computer and checked on our server. Guest play is never saved. If a parent picks a child profile, only right or wrong per puzzle (plus any “how sure” tap and computer-check choice) is saved to their account. The computer and robot samples are written by our puzzle code, not a chatbot, and are sometimes wrong on purpose.
