Umbra — Carve the light

A solid block. Three shadows — front, side, top. Carve away everything that doesn't belong. A new puzzle every day, the same one for every player in the world.

A solid block floats in the dark. Three shadows are given — one from the front, one from the side, one from above.

Carve away everything that doesn't belong, until the shape you have left casts all three exactly.

Any shape that fits will pass. But there is always a smaller answer, and finding that is the real game.

WHAT IT FEELS LIKE

There is no tutorial. The first puzzle is a small cube with two shadows already matching, and one tap finishes it. You'll understand the whole game before you've read a word.

No timers, no lives, no energy meter. Undo as much as you want. Rotate the block, look at it from another side, take an hour if you feel like it.

Each shadow locks into place the moment it matches. Getting the third one to click is the point of the whole thing.

WHY IT'S HARDER THAN IT LOOKS

There's an easy answer to every puzzle: keep every block that all three shadows permit. It always works and it's never elegant.

The real answer is smaller — often much smaller. One block can cast a shadow in two directions at once if you place it right, so the question stops being "what can I keep" and becomes "how little can I get away with."

That gap between the obvious answer and the best one is the entire game, and it never closes.

Made for anyone who likes a quiet problem and no one shouting at them about it.
