Marble Rails: Sort Puzzle

Tap a marble, watch it roll, merge three of a color.

Marble Rails is a relaxing color sort puzzle built on a wooden marble run. Tap a marble and it hops onto the rail, rolls down every floor and rides the lift back to the top. When it passes a garage with room for its color, it drops in on its own. Three marbles of one color merge with a satisfying click. Clear every marble to win.

Easy to learn, hard to put down: the rail holds only a few marbles at a time, so the order of your taps is the puzzle. Plan ahead, keep the rail moving and never run out of room.

HOW TO PLAY
- Tap a front-row marble, or the bottom marble of a tube, to send it onto the rail.
- Each marble drops into the first garage on its way that takes its color.
- Three of a color in a garage merge and make room for more.
- Clear the whole board to win. Rail full and nowhere to go? Use a booster, continue or try again.

NEW TWISTS AS YOU PLAY
A new mechanic arrives every few dozen levels, each with a short intro the first time you meet it:
- Hidden marbles that show their color only at the front
- Frozen marbles that thaw as you make merges
- Caged marbles you match right where they stand
- Shutters that close a garage for good once it is empty
- Color garages that take only their own color
- Gift marbles that keep their color a surprise until you send them
- Chained garages that open after enough merges
- Sticky marbles that travel in pairs
