Rail Tangle: a puzzle where you bring the trains together, not apart
In front of you sits a field bristling with scrap track. The stations are already in place; the switches between them are turned every which way. Rail Tangle is not an arcade about speed but a calm logic problem: rotate a tile with a single tap until an unbroken line runs from every station to its matching one.
You rotate, you don't build
Unlike road builders, you can't add a new piece of track. Everything is already on the board — you only turn each tile to the right quarter. A tap or click spins it clockwise, a right-click or Ctrl+click counter-clockwise. That reframes the puzzle as an orientation task: the solution is fixed by shape, and all the sport is in seeing which way each joint points.
A train runs only over a whole line
A level is cleared not for "almost connected" but for a closed route: a train travels station to station along an unbroken line, and only then does the level count. So every joint matters — one tile turned the wrong way breaks the line mid-way and turns a tidy diagram into a pile of dead ends.
Fixed tiles are the logic's anchor
Some cells are highlighted as stations and won't rotate. They lock in the only legal exit from the platform, so they're the right place to start: dock the route to the irreplaceable joint first, then finish the middle. On top of that the field hides decoys — extra turns that beg to join the line and only tangle you. The real difficulty is not one route but keeping several from fighting over the same switches.
Par: the move counter as a measure of taste
Every level has a par — the minimum number of turns the author intended. You can clear it wastefully, jamming tiles at random, but the honest result is landing on par. Then you didn't brute-force it, you actually saw the whole solution.
Six boards and an endless generator
There are six handcrafted levels, from a three-cell warm-up to the six-column "Tangle" where two trains cross. The "Random Board" button generates a fresh, guaranteed-solvable puzzle — the engine carves a route, shuffles it, and checks a solution exists, so dead fields never happen. The game is translated into Russian and English and answers a mouse or a finger just the same.
Bottom line
Rail Tangle is quiet where arcade games are loud. No timers, no enemies, no sound — just you, a field, and the knowledge that every tile remembers its one correct turn. Work the knot, and the trains will run themselves.
