How to play Lampwise

1. Put lamps on the open tiles until every tile is lit.
2. A lamp lights its whole row and column, until a wall stops the light.
3. No lamp may sit in another lamp's light.
4. A number on a wall says exactly how many lamps touch it, above, below, left and right.

Tap a tile once for a lamp, twice to mark it with a dot as "no lamp here", three times to clear it. Drag across tiles to dot several at once. Every puzzle has one answer, and you can reach it by logic alone, no guessing.
