DotTracks — Color Train Puzzle

DotTracks is a calm, minimalist train track puzzle — draw the rails, mix the colors, and route every train home, like a trainyard. Free, no ads, no signup.

Each level gives you a grid, a few colored trains, and matching stations. Your job: draw tracks so every train reaches the right station. Start with simple straight paths. Soon you'll be merging trains at crossings, splitting them at junctions, and routing three colors through the same shared corner — one wrong tile and a blue train ends up at the red dock. A logic puzzle that's easy to learn and tricky to master.

• 37 hand-crafted levels across three packs (more on the way)
• Merge, split and mix train colors at crossings and junctions
• Rate the difficulty of every level you solve
