Little Railways: Train Tracks

Little Railways is a logic puzzle in the family of sudoku and nonograms. Each board hides one railway line: lay a single track from station A to station B, with as many pieces in each row and column as the numbers on the edge say. Every board has exactly one solution, and you can always reach it by reasoning. No blind guessing. HOW IT PLAYS • One track, from A to B. It never crosses itself and never closes a loop. • The numbers say how many squares of each row and column carry track. • Drag to lay rail. Tap to plant a pine where no track goes, or to save a square for track. • Tap a number to fill in what is already certain on its line. BADGER OR BEAR You work with one of them. The badger is the station master: proud, punctual, rules things out first. The bear drives the engine: lays first, asks later. Either will tell you where to look for one ticket. When a count breaks, the board tells you why, for free. And the handcar tests your line whenever you like. AS HARD AS YOU WANT Six board sizes, from a quick 5×5 to a 10×10. And three ranks you choose yourself, at any size: Apprentice (counting settles everything), Officer (look one step ahead now and then) and Inspector (few clues, plenty of thinking). Your companion dresses for the rank. THINGS TO SPEND TICKETS ON Finish a line and the train crosses it while the rest of the board turns back into forest. Lines pay tickets. Spend them at the platform shop on wagons for your train, on the four seasons, and on things for the forest: a deer, a beehive, a cat. CALM BY DESIGN • No ads. No timers. • iPhone and iPad. • Your progress is saved to iCloud. • Works offline. • English, Spanish, French, Italian and Portuguese. Little Railways is free. If you enjoy it, you can buy the developers a coffee from the shop. It’s optional, and the station says thanks with tickets.
