Pixel Sign

Turn a dark diode panel into a finished sign. Every row and column lists its ordered runs of lit cells. Leave a gap between separate runs, stamp cells lit or empty, and satisfy every clue to finish the sign.

Eighteen different signs invite careful deduction. Visit the line workbench to inspect every compatible pattern for a selected row or column, then clear that line's marks if you want to reconsider it. The fuse bench can spend one of two fuses on a cell only when every completion allowed by the public clues agrees on its value. An undo voucher restores the actual marks and fuse resources from the previous edit.

Beveled glass cells, bright filaments and a dark enamel frame bring each solved pattern to life. Exact clues and empty marks remain visible throughout the puzzle. Retry any sign or revisit a different chapter whenever you wish.
