02 · Find your rhythm
Try organizing the top row, then working down. Sometimes you need to move a correctly placed tile to make room. There is no move limit or time limit.
03 · Another little challenge
Solve a board to celebrate and unlock Next level. Each difficulty has ten levels with progressively longer random shuffles. Shuffle length is not a guaranteed minimum solution length; some boards will feel easier than others.
04 · Room to try again
Undo reverses a move and its move count. Restart resets the same board and timer. New shuffle makes a different starting board for the current level. Changing difficulty or refreshing starts at level one. Mini mode preserves the current run.
A few little answers.
Can I get an impossible puzzle?
Each board starts solved and is shuffled through legal moves. That means a route back to the solution always exists. A puzzle never starts already solved.
What happens after level ten?
You complete that difficulty and can play a fresh set or switch to a different board size. New shuffles keep the levels varied. No progress is stored after refreshing.
Can I take a break?
Pause hides the board and stops the timer. Leaving the game window or switching tabs pauses a started game. Return and choose Resume when you are ready. Once loaded, play needs no network connection; reloading offline is not supported.
