How to play Jev Code Breaker

Build a four-symbol guess, read exact and misplaced feedback, and crack the code in eight accepted guesses.

1

Choose four unique symbols

Fill all four slots from the six original geometric symbols. Symbols do not repeat.

2

Submit one guess

A valid set of four different symbols uses one of your eight guesses.

Read the feedback

Exact means the right symbol in the right slot. Misplaced means the right symbol in another slot.

4

A run ends when all four positions are exact or the eighth accepted guess is used.
