Flow Laser Quest

Flow Laser Quest is set inside a computer world, and its puzzles are built from coloured points on a grid of squares. The points come in pairs that share a colour, and your task is to join each one to its partner by sliding a path through the squares that lie between them.

The developer spells out one rule: a path may not pass over a path you have already made. That restriction is what stops a level from being a matter of drawing straight lines. Once one colour's route is laid, every later route has to find a way around it, and a careless early link can leave a pair with nowhere to go. The developer puts the size of the game at a hundred levels and frames it as a test for the brain. It works with a click on a computer or a touch on a screen.

Click or touch one of the coloured points, then slide towards the other point of the same colour. Your path is laid through the squares that make up the level as you move. Reach the matching point to complete the link. Repeat for every colour, keeping in mind that a new path may never run across one you drew earlier.

With crossing ruled out, the order of your links matters as much as their shape. Look for a pair whose route is obvious and join it first. Each finished path narrows the options for the others, which often makes the remaining routes easier to spot rather than harder, as long as none is blocked.
