About Brainblox

A hidden code fills a wide, shallow box. Your job is to work out which of the eight blox belongs in each position. After every guess the traffic lights tell you how many pieces are exactly right, how many are the right piece in the wrong place, and how many are not in the code at all.

Build a square wall using all eight blox. Each day brings three new clues about colour and placement, plus the standing rule: no two blox of the same colour may touch side to side, end to end, or corner to corner.

The daily challenge is generated from the calendar date, so everyone in the world sees the same Blox in the Box code and the same Brainblox wall. You get three lives per puzzle — spend one to lock a correct blox in place if you need a hand.

When you're done, copy a spoiler-free result block and challenge your friends. The text reveals how many guesses or attempts you used and how many lives you spent, but never the solution itself.

Brainblox is free to play. If you'd like to help keep the puzzles coming, you can support Brainblox here.
