About the River Layout

The River layout traces a wide, winding ribbon of tiles that snakes down the board in a long S-bend, entering near the top, curving back on itself in the middle, and spilling out toward the bottom. There are no straight walls here and no tidy rectangle to lean on. Instead the tiles flow like current around two big bends, the band swelling a little where the water would run deep and pinching where it narrows. Because the shape is essentially a thick line rather than a solid block, much of the river is only one or two tiles deep, which keeps a generous number of pieces exposed at any moment.

At 2 out of 5 difficulty this is a relaxed, forgiving board, a good one to play with a cup of tea rather than a furrowed brow. The long thin form means you are rarely hunting blindly through a deep stack; most of what you need is sitting right there along the banks. The gentle challenge comes from the curves, where tiles double up and one piece can quietly pin its neighbor. Clear those bend points and the whole river tends to drain smoothly from both ends toward the middle.

How to Clear the River Layout

Start at the mouths. The two open ends of the S, the very top of the river where it enters and the very bottom where it exits, are your most reliable free tiles because nothing flanks them on the outer side. Peel pairs from both ends at once so the ribbon shortens evenly rather than leaving one long tail you cannot reach.

The real work is at the two bends. Where the river curves back on itself the band is thickest and often layered, so tiles there block more neighbors than anywhere else on the board. Treat each curve as a small knot: open the outer edge of the bend first to expose the inside of the turn, and resist stacking up matched-but-trapped pairs deeper in the curve.

Watch the narrow neck in the middle where the two bends meet. This pinch point is the crux, because the upper half and lower half of the river effectively join here, and a single stubborn pair can split the board into two stranded sections. Keep at least one easy match in reserve near the neck so you always have a move that reconnects the flow.

For the endgame, work both ends inward toward that center neck so the last tiles meet in the middle rather than getting marooned at a far bank. Since flowers match any flower and seasons match any season, save those wild-feeling tiles to break an awkward standoff on a curve. And if the current ever feels truly stuck, the Shuffle button re-deals the remaining tiles into a fresh solvable arrangement, so a dead end is never really the end.

The Story Behind the River Layout

A river is one of the most natural shapes in the world to render as a winding line, which is exactly why it suits Mahjong so well. Real rivers carve those lazy S-bends, called meanders, because flowing water erodes the outside of each curve and drops silt on the inside, slowly snaking the channel back and forth across a valley over centuries. The layout borrows that same sinuous logic, so the board literally looks like a stretch of water seen from above.

That meandering form is what makes the River fun to play rather than just pretty to look at. A straight canal would be dull and a solid lake would be a wall of tiles, but the curving ribbon gives you long open banks for easy matches punctuated by tricky bends, the same way a real river alternates calm stretches with churning turns. It rewards a calm, flowing rhythm of play that mirrors the thing it depicts.

Frequently Asked Questions

Is the River layout good for beginners?

Yes. At 2 out of 5 it is one of the gentler boards. Because the tiles form a thin winding band rather than a deep pile, most pieces stay exposed along the banks, so you usually have plenty of legal moves and rarely get blocked for long.

Where should I make my first moves on the River?

Begin at the two ends of the S, the top entry and the bottom exit, where tiles are open on their outer side. Clearing inward from both mouths shortens the ribbon evenly and keeps the middle reachable.

Why do I keep getting stuck at the curves?

The bends are where the band is thickest and tiles overlap most, so a piece there can pin several neighbors. Open the outer edge of each curve first to expose the inside of the turn, and avoid leaving matched pairs buried deep in a bend.

What happens if I run out of moves?

Press Shuffle. It re-deals all the remaining tiles into a new arrangement that is still guaranteed solvable, so you can keep playing the same River board instead of restarting from scratch.
