DotTracks vs One

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.

Draw one line. Run the shift. Watch every parcel find its way. One-Line Factory is a compact logistics puzzle about planning one continuous conveyor from IN to OUT. Guide every parcel through its stations in order, then start the line and see whether your design can meet the quota before time runs out. MASTER 36 HANDCRAFTED BOARDS Six factory departments build on the rules one shift at a time. Route around blockers, obey one-way gates, balance limited belt tiles and tight corner budgets, use fast and slow cells, cross your own path with overpasses, and time shutters that open and close on their own rhythm. COMPLETE, THEN OPTIMIZE Solving a board is only the start. Rework your route to earn three independent stamps: - Completion — deliver the full quota - Compact — stay within the route target - Express — beat the expert time CLOCK ON FOR ENDLESS SHIFT Unlock an ever-changing mode where each procedurally generated floor has a route to discover. Keep going as quotas, blockers, and the clock grow tougher from shift to shift. DESIGNED FOR TOUCH Draw with one finger and drag backward to erase. Start the conveyor whenever you are ready, watch the parcels move, then adjust your line and try again. Solver-backed hints can give you a nudge without solving the whole board for you.
