One cell means one block
The grid is a placement map, not a true-size ruler. Different block sizes will still make the same design when the row and column counts stay the same.
Check the number and quantity key first
Every colored cell carries a number, and the key lists how many blocks of each color to prepare. A similar light or dark shade is a perfectly good substitute.
- Sort the required quantity for one color at a time
- Use the bold five-cell guides to check position
- Start with the center or the longest row
Supervise small parts
Blocks are small enough to be swallowed. Keep them away from children under age 3, supervise ages 6–7, and put unused pieces back into a closed container after building.
