DotTracks vs Arrow Loop

DotTracks is a calm, minimalist train track puzzle — draw the rails, mix the colors, and route every train home. 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, repainting them at paint stations, 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. • hand-crafted levels across four packs (more on the way) • Merge, split and mix train colors at crossings and junctions • Repaint trains at paint stations — white trains are neutral until colored • Rate the difficulty of every level you solve • Free and ad-free: no account, no email, no interruptions • Works offline — built for short breaks, train rides, and the quiet 5 minutes before sleep • Available in English, German, French, Italian and Spanish Your progress is backed up automatically under a random ID — no personal account needed.

Sharpen your logic in quiet focus. One loop. A few shaded cells. That's the whole rule — and the longer you look at the board, the clearer your mind becomes. Use the arrow-and-number clues to shade exactly as many cells as each arrow points to, then draw a single closed loop through every remaining cell. Shaded cells never touch side by side, and clue cells are never shaded or crossed by the loop.
