Two ways to play, one brain teaser

Pick a mode and start
training your spatial sense.

Every stage is a clean, textbook-style front view of stacked cubes. Read the depth, picture the full 3D shape, and answer before the timer runs out — earning stars, gems, and a daily streak as you climb.

Mode 1

Count All

Count the whole stack — including every block hidden behind the ones you can see.

1Check each column's height from the top.
2Remember: no gaps between the blocks.
3Add up every column for the answer.

Mode 2

Count Hidden

A tougher twist — find only the blocks hidden completely behind the others.

1Picture the stack's full 3D shape.
2Find blocks covered on every visible side.
3Count those hidden blocks for the answer.
