Tiny Trains is a calm railway logic game about drawing tracks, planning routes, and guiding every colorful train to the right station. Start with simple connections, then master shared tracks, switches, color mixing, painters, splitters, obstacles, and precise timing. BUILD A WORKING RAILWAY Every level is a compact railway system waiting to be completed. Study the starting points, stations, colors, and special pieces. Draw the tracks, connect the network, and press Play to see your plan come to life. There is no single path you must copy: experiment, rebuild, and discover a route that works. MASTER COLOR LOGIC Stations accept only the correct trains, so every connection matters. Merge trains to create new colors, use splitters to send one train along two routes, pass through painters to change colors, and build around obstacles. Later puzzles combine these rules and ask you to coordinate several trains across the same network. PLAN THE ROUTE AND THE TIMING A railway can look perfect and still fail when two trains arrive in the wrong order. Think ahead, decide which tracks should be shared, and control when trains meet. Pause the simulation, move through time step by step, and watch exactly where your design needs to change. Undo and redo make it easy to refine the tracks without starting over. LEARN WITHOUT THE RUSH Guided, hands-on tutorials introduce each mechanic while you play. The difficulty grows naturally from short connections to layered networks with color changes, merges, splits, and carefully timed arrivals. There are no countdowns or reflex challenges. Take as long as you need and enjoy the satisfying moment when the entire railway finally works. SAVE AND IMPROVE YOUR SOLUTIONS Your unfinished board is saved automatically, so you can leave a puzzle and continue later. Completed routes are saved too, making it easy to revisit an elegant solution, try a completely different design, or share your finished railway.
