How to play BlockGuesser

Every day there's one small tower of coloured blocks in a 4×4×4 space. Your job: rebuild it from memory, as fast as you can.

1 · Study

The block appears in 3D for a few seconds. Memorise the shape and the colours, then it hides. Tap Ready to start early.

2 · Build

You build one layer at a time, bottom to top. Pick a colour, then tap the squares in the layer grid to place blocks. Use the layer buttons to move up and down; a live 3D preview shows what you've built. The clock is running.

3 · Peek

Forgot a corner? Hit Peek to see the target again for a moment — but each peek adds +10 seconds to your time, and you only get 3.

4 · Submit

Press Submit when you're done. Match the target exactly — every block in the right place and the right colour, with none extra — to solve it. Your score is your time plus any peek penalties.

Sharing

Afterwards you can share a spoiler-free result — your time, peeks, and a row of squares showing how each layer went. No shape given away.

Every day

A new block appears each day, the same for everyone. Missed a day? The archive has every past block.
