Read from the board image on this page, last measured 2026-09-29. Colour names are read off the hex shown beside them and may differ from the name the game gives that colour. The game decides which colour is playable at any moment, so treat this as what the board costs to clear, not as a play order.

How to read the Level 840 board

Start with the biggest colour: blue

blue covers 26.3% of the board - more than any other colour here. A colour only clears once every part of it has been taken off the board, so the biggest colour is the slowest to finish and the one worth starting on as soon as the game offers it.

orange is spread across the picture

orange sits in 35 separate runs in the board image, so it cannot be finished in one place. Take the runs you can reach and come back to the rest as the colours around them clear.

Ignore the empty background

The cream area is 18.5% of the board and sits outside the picture. Nothing was measured against it, so it does not count towards the clear.
