How to play Tintlock
Tintlock is a code-breaking puzzle: you work out a hidden code of colors from the clues each try gives you.
The lock has a secret code of colors. Fill a row and try it: a dot means a right color in the right spot, a ring a right color in the wrong spot. The marks don’t say which color they mean. Crack the code before you run out of tries.
Tips
- Use your first tries to learn which colors are in the code at all, for example with two pairs of colors.
- Change one or two things at a time. When the marks change, you know which change did it.
- Only try codes that fit every clue so far. A guess that can’t be the answer wastes a try.
