About this game
How Simon works
Simon presents a growing sequence using four named pads: circle, triangle, square, and star. You repeat the whole pattern after each playback, rather than pressing only its newest addition.
Objective and win/loss conditions
Repeat sequences correctly until you complete the 12-pad target. The first wrong pad ends the run. During your input turn there is no deadline for deciding which pad to press; playback timing is separate from the guessing rules.
How it plays
Start pattern shows the first pad. After a successful repetition, one random pad is appended and the longer sequence plays from its beginning. Repeated pads are possible.
If one round shows circle, star, triangle, your response must be circle, star, triangle in that order. If the next round adds another star, you repeat all four pads, not just star. Input during playback is not a substitute for waiting for your turn.
Calm pattern changes the presentation to slower, longer-held highlights and named cues. It does not shorten the pattern, remove repeated pads, or change the target of 12.
Scoring and strategy
Best remembered measures the longest sequence you fully completed. Remembering the first three pads of a failed four-pad round does not count as completing four. There is no bonus for rapid responses.
Try grouping a longer pattern into short named chunks. A repeated pair such as star, star can be remembered as a pair without losing its two required presses. Choose the presentation you find easier to follow, and keep using the pad names when color alone is not useful.
Local save data
nocharge:simon:best-length stores the longest completed sequence, and nocharge:pref:simon-calm remembers Calm pattern. Neither the current generated sequence nor your partial response is a saved session. Closing the page ends that run, while the best-length record remains in the same browser until cleared.
