COGNITIVE ARCADE / FREE BROWSER PUZZLES
REWIND
Play REWIND free: remember luminous number sequences and reproduce them backwards. Six progressive stages, daily puzzles and unlimited practice.
Keep the numbers. Change their order.
REWIND shows a sequence one number at a time. Once playback ends, reconstruct it from last to first. Six stages increase the sequence length from three to eight numbers.
The last two stages add a twist
Stages 1–4 ask for a simple reversal. Stages 5 and 6 ask you to reverse the sequence and add one to each number. After 6 comes 1: a displayed sequence of 2, 6, 3 would become 4, 1, 3 under REVERSE + 1.
Three chances
A wrong input ends the current stage and uses one chance. Move to the next stage to continue. Three mistakes end the run. Correct inputs and completed stages earn points; completed stages also earn a response-time bonus.
Controls and practice
Use the numbered buttons or keyboard keys 1–6. Watch the full sequence before responding: the buttons become active at YOUR TURN. Start with practice to learn the reversal rule before taking the daily challenge.
Daily challenge and privacy
Players using the same version on the same UTC date receive the same daily sequence. A started attempt resumes in the same browser after a refresh. Local storage and the device clock control this local challenge; changing either can affect it. Records stay in your browser. There is no global leaderboard, account system, paid COMPETITOR access or in-game analytics in this release.
