Grid Lines

Connect the colors. Fill the grid. Breathe out.

Draw paths between matching colored dots, tap tiles to turn their walls, and find the way every line fits until the whole board glows.

How it plays

• Connect every color. Paths run straight or turn corners, and different colors never cross.
• Turn the tiles. Some tiles have walls you can rotate with a tap. Some of them are red herrings.
• Fill the grid for three stars. Any solution that connects everything wins; covering every tile earns the full set.
• No pressure. No timers, no move limits, no way to fail. Stuck? Take a hint.

What's in the flask

• Nearly 200 hand-picked levels, from a gentle tutorial to genuinely tricky.
• Three looks: Midnight Lounge, a sunny Miami, and a darker Cyberpunk.
• Music that grows out of the paths you draw.
