Cloudline Connect

Cloudline Connect is a path-drawing puzzle set among floating pillars in the sky, and its single constraint is the one that makes it hard: paths cannot cross or overlap. Each level gives you coloured points and asks you to connect matching pairs, which sounds trivial until the board fills and a route that solves one pair makes another impossible. The real requirement is buried in the rules — you have to use all the available space, so a solution is not just connecting everything but connecting everything in a way that leaves no gaps. As levels progress, more colours arrive and the spaces get tighter, turning a gentle puzzle into a genuine test of planning.
