Signal is a minimalist grid puzzle, and Jean-Marc's very first game. Pick a piece, place it on the grid, rotate it, then press Emit to send the signal from its source: every target has to light up.
Ninety hand-made levels across three difficulty tiers use six kinds of pieces, from arrows and splitters to mirrors, filters and teleporters. It plays in desktop and mobile browsers, saves your progress, and it is free.
