Shadow Puzzle: 3D Brain Game

A shadow puzzle in 3D: a light, three walls and one carved block. Turn it until every shadow fits.

★ Quarter turns, nothing else
Spin, tip and roll the block. Every turn throws a different shape onto the floor and walls.

★ One wall, then two, then three
Early acts ask you to fit one shadow. Later ones ask for all three at once.

★ Beat the best
Every act knows its fewest turns. Match it for three stars.

★ Endless and always fair
New acts keep coming and every one can be solved.

★ Stuck? Ask for a hint
A hint lights up the next right turn. You get 3 to start, and a short video gives 5 more.

★ A quiet theatre
A dark stage, a single spotlight and a marble block. No timer, no rush.
