About this game

Simon Says is a memory game built around an electronic toy from 1978 — four coloured panels that light up in a sequence you have to copy back. The sequence grows by one panel each round. Most people stall somewhere between rounds 8 and 15; the world record is over 60.

The real trick isn't raw memorisation — it's chunking. Group the sequence into runs of three or four (rather than individual colours) so your short-term memory only holds 3-4 "items" instead of 12 separate panels. Closing your eyes between rounds and quietly speaking the sequence as it plays also helps; verbal rehearsal extends working memory significantly. Children, surprisingly, often outscore adults because they don't over-think.
