About Chess Shuffle
A daily shuffle of ten chess puzzles, solved against a 60-second clock. One attempt at flashing the whole set on the first try — that's the prestige play.
How the daily shuffle works
Each day at midnight a new shuffle of ten puzzles unlocks. You can preview the positions as long as you like. When you hit Start, the 60-second countdown begins and the puzzles are reordered randomly. Solve each one in a single move to advance.
Practice shuffles
Signed-in users can generate practice shuffles from the home page any time. They use the same 10-puzzle, 60-second format as the daily shuffle.
Practice shuffles won't extend your streak and can't earn a flash — they're for warming up or exploring more puzzles. Your practice results show up in your History and Stats so you can track your own improvement.
Success and failure
Solve all ten before the timer runs out and the day's shuffle counts as a clean completion. A wrong move or a timeout ends the run. You can try again as many times as you like, but only the first attempt of the day can earn a Flash.
Flash streak vs Daily streak
Your Flash streak counts consecutive days where you cleanly completed the shuffle on your firstattempt. It resets the moment you need a second attempt or miss a day — that's why it's the one to chase.
Your Daily streakcounts consecutive days where you cleanly completed the shuffle, regardless of how many tries it took. It's the more forgiving metric and only resets if you miss a day entirely.
