How many cubes are there in the building shown by this plan?

Each cell shows how many cubes are stacked in that column. An empty cell means no cubes there.

What does the generator do?

The generator creates a random plan – a top-down grid where each cell holds a number telling you the height of the column at that spot. Some cells may be empty (no cubes there).

How to use it

Read the number in each cell – it tells you how many cubes are stacked at that position. Add up all the numbers and that is the total number of cubes in the building. Empty cells contribute zero.
