Rule 01Crack the hidden code.

Today’s code is a row of coloured pegs: four at the first two tiers, five at the top. Every colour also has a letter and a shape. Fill a row with colours and try it.

Rule 02Every guess is scored with dots.

A filled dot for each peg of the right colour in the right slot, a hollow dot for each right colour in the wrong slot. The dots never say which peg they belong to.

Rule 03A colour counts only as often as the code has it.

Two B pegs against a code with one B earn one dot, not two. At the first tier the code never repeats a colour; above it, it may.

Rule 04Crack it within the guess limit.

Ten guesses at the first tier, eight at the second, ten at the top. A code you already tried is not scored again. Stuck? A hint places one peg of the code.

Tap a colour to fill the next slot · tap a placed peg to take it out · ✓ tries the code · keyboard: letter keys place, Backspace removes, Enter tries
