A2B Railways

One line from A to B. A brand-new puzzle every day.

A2B Railways is a daily logic puzzle in the classic "train tracks" style. Every day everyone gets the same fresh board, built from that day's date — so you can race friends on identical track. Your job: connect the two towns, A and B, 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 single winding path from town A to town 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. Your call, every day.

FEATURES

• A new puzzle every day, identical for every player.

• Four board sizes from a relaxed 7×7 up to a meaty Expert grid.

• Smooth, hand-drawn rails that curve through every junction.

• Undo, redo and restart freely — experiment without fear.

• 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.

• A satisfying train-and-confetti finish when the line finally connects.
