Codebreaker — Quick rules

Goal of the game

Find the hidden code in as few guesses as possible. If two players finish in the same number of attempts, time is used only as the tiebreaker.

Rules

Rule 1

Your goal is to discover the hidden code.

Rule 2

Every digit in the code is different. Zero is allowed, including in the first position, so 0123 is a valid code.

Rule 3

A green marker means: correct digit, correct position.

Rule 4

An orange marker means: correct digit, wrong position.

Rule 5

The markers are grouped together rather than placed under the digits they refer to. You have to work out which positions they describe.

Rule 6

Ranking is based first on the number of guesses. Time is used only to break ties. You can keep guessing until you find the code.
