One line from A to B, and a brand-new puzzle every day. Everyone gets the same board, built from that day’s date, so you can race friends on identical track. Connect the two towns with a single unbroken railway that threads the whole grid.
How to play
- The number beside each row and above each column tells you exactly how many track pieces belong there — no more, no less.
- Lay straights and curves so the rails line up edge to edge into one continuous line.
- A few pieces are placed for you at the start as clues.
- Finish the winding path from A to B and watch the train run it end to end.
Four daily levels
Easy, Medium, Hard and Expert — each a larger board built from the very same day’s seed. Start gentle and work up, or jump straight to Expert.
Features
- A new puzzle every day, identical for every player.
- Four difficulties, from a relaxed Easy board of 7×7 or 8×8 up to an Expert grid of 10×10 or 11×11.
- Smooth, hand-drawn rails that curve through every junction.
- Undo, redo and restart freely.
- A “lay next piece” hint when you want a nudge, never the whole answer.
- A local leaderboard tracking your best solve time at each level.
- Online leaderboards for the fastest solve at every level: Game Center on Apple devices, Google Play Games on Android.
- Play by touch or with a mouse. On Android, play by keyboard or with a game controller too — with a Swap A/B option for pads that put the buttons the other way round. Keyboard and controller play is coming to iPhone, iPad and Mac in the next update.

Private by design
No accounts, no ads, no tracking. The game runs entirely on your device. The only thing that ever leaves it is a leaderboard time — through Game Center on Apple devices, or Google Play Games on Android — and only if you are signed in to that service. See its privacy policy.
Platforms
Native on iPhone, iPad and Mac, and on Android phones and tablets. Every platform gets the same daily board, built from the same date, so it makes no difference which one you race on.
