Traindoku: Train Track Puzzle

Build the railway, one clever deduction at a time. Traindoku is a logic puzzle where you lay train track across a grid to connect two stations. The numbers around the board tell you exactly how many track pieces belong in each row and column - your job is to work out where they go. HOW TO PLAY • Drag across the grid to lay track between the stations • Match every row and column count • Join all the pieces into one single route - no loops allowed • Cross off cells you know are empty to narrow down the gaps When the route is complete, watch your train steam through a cosy low-poly countryside. FEATURES • Pure logic - every puzzle can be solved by deduction, no guessing required • Gentle learning curve: start on small 4x4 boards and work up to tricky 8x8 grids • Endless fresh puzzles, with hard levels and breather boards mixed in • Stuck? Use a hint to reveal the next logical step • Three hearts per level, so think before you lay • Satisfying track-laying, sound effects and haptics If you enjoy Sudoku, Nonograms or other number puzzles, Traindoku puts a fresh, relaxing spin on grid logic. All aboard!
