Simon wants to challenge your memory skills. Think you have what it takes?
Start by selecting your desired difficulty (5, 10, or 15 levels) then press the "Start Game" button. Simon will give the first signal. Repeat the signal by clicking the corresponding block. If correct, you can proceed to the next round.
With each new round, Simon will duplicate the previous signal(s) and add one. Continue playing as long as you can repeat each sequence of signals correctly. Enjoy!
