Brainblox strategy tips
How to spend fewer guesses, fewer lives, and less time staring at eight wooden blox.
Blox in the Box
Open with the big pieces
The large green blox only fits one way and the large red and blue eat most of the box. Placing them first tells you far more per guess than filling corners with small blox.
Change one thing at a time
If you move two blox between guesses and the green light goes up by one, you can't tell which move caused it. Isolate a single change and the lights become an answer rather than a hint.
Amber is your friend
An amber light means the right blox in the wrong place — that piece is definitely in the code. Keep it on the board and shuffle its position rather than swapping it out.
Red means retire the piece
A red light says a blox isn't in the code at all. Park it and stop testing it; the pool of candidates shrinks fast once you trust the reds.
Brainblox walls
Start from the standing rule
No two blox of the same colour may touch — including corner to corner. With two blox of most colours, this alone rules out a surprising number of layouts before you read a single clue.
Read the clues as constraints, not instructions
A clue about edges or corners rarely tells you where one piece goes. Use it to eliminate whole families of layouts, then place the piece the eliminations leave you.
Fill the awkward gaps first
Any square the small blox can't reach must be covered by a large piece. Find those squares early and the wall largely builds itself.
When to spend a life
You get three lives per puzzle, and each one locks a correct blox in place. Spend one when you're genuinely stuck rather than early on — a locked piece is worth much more once you've already eliminated options, and your shared score shows how many you used.
Practise without cost
Practice mode serves unlimited random codes and walls and never touches your daily score — the cheapest way to get a feel for how the pieces tessellate.
