Levels 7–10

Secret Bottle Order

Deduce a hidden bottle permutation using only the total number in correct positions.

How to play

Arrange each distinct bottle once and submit your guess. Feedback gives only a count of correct positions, never which bottles. Keep earlier guesses and compare ideas.

Try an optional two-bottle practice, then three or four bottles at the shared profile level. Candidate comparison checks aggregate counts against previous guesses. Attempts are unlimited. Undo and Reset change only the arrangement; submitted guesses remain. Next puzzle waits for you.
