Bottle Code
About this game
Solve a hidden bottle order by rearranging colors and comparing checks. The number reports correct positions without telling you which positions they are. Because the hidden order stays fixed during a puzzle, each small experiment can narrow the remaining possibilities.
Controls
Tap two bottles or drag one onto another to swap them. Check order tests the visible row; History shows earlier checks, and Undo swap reverses an exchange.
How to play
- Choose the bottle-count mode before starting the puzzle.
- Match the hidden arrangement exactly to complete the puzzle.
- A check counts correct positions across the whole row.
- Player-set locks hold positions until released.
Ways to play better
- Change one pair at a time so two checks remain easy to compare.
- Record the arrangement behind a high score, not just the number.
- Treat a lock as a working decision until the evidence confirms it.
Common questions
Does a score of two identify the correct two bottles?
No. It gives the total number of correct positions. Compare arrangements that differ in a small, known way to learn more.
Does locking a bottle prove it is correct?
No. A lock protects a position you choose; it is not confirmation from the hidden answer.
