Loading Triangle Light Maze…
A build-and-solve puzzle on a triangular grid of up to 30 rows. You choose which points glow, and the solver works out the top-to-bottom route that collects the most of them, showing the path, the score and the share of lights it caught. Every board you make is a fresh puzzle, and there is no clock.
