Light Code

Loading…

Difficulty

A code of 4 symbols out of 5, repeats allowed, and 7 tries. The lights tell you the position.

There is a hidden code of symbols and only a few tries. After each try the board answers with lights: green if a symbol is in the right place, amber if it is in the code but somewhere else. Three codes per run.

What it shows

Pure deduction: computed hints, score for unused tries and a test bot that solves by reasoning, without peeking at the code. The level changes the code length, the symbols, the tries and how much the lights tell you. Each level keeps its own best score.
