Nightlight Ledger

HERE’S
THE IDEA.

Toggle a square to light it. In each row, a lit square contributes its column number, starting at 1. In each column it contributes its row number. Match every printed row and column total, then Check ledger. A light can satisfy both totals at once.

Pause, restart and adjust effects inside the player. Automatic previews never save results. Your progress shows its save status while you play.
