Mahjong Connect (Shisen-Sho)

How to Play Mahjong Connect

Mahjong Connect — known traditionally as Shisen-Sho — takes the mahjong tile set out of the pyramid and lays it flat. Every tile sits in a single layer on a rectangular grid, and instead of digging down through stacks you are looking for routes: two identical tiles clear together when a line of empty cells can be drawn between them.

That line has one rule, and the whole game lives inside it. It travels only horizontally and vertically, only through cells with no tile in them, and it may turn a corner at most twice. A straight run along a row is zero turns. An L-shape is one. A Z or a U is two. Anything that needs a third corner is not a legal move — yet.

The move most new players miss is that the line may leave the board. A one-cell margin runs all the way around the grid and is always empty, so a tile on the top row can go straight up and out, run along the outside, and drop back down onto its twin on the far side — two turns, no matter how much is in the way between them. The same is true down the sides and along the bottom. Edge tiles are therefore the most flexible tiles on the board.

Matches follow the standard mahjong set: identical suit tiles (same suit and number), the same wind, or the same dragon. Flowers and Seasons are the exception — any Flower pairs with any other Flower, and any Season with any other Season, even though the pictures differ. Those tiles carry a coloured wash and a 花 or 時 badge so you can see the group at a glance.

When a pair goes, it leaves a gap. Nothing falls, nothing slides across — the board just gets holier, and holes are lanes. Clear the last pair and the board is yours.

Strategy Tips for Shisen-Sho

• Work the edges first. Tiles on the border can always reach the outside margin, so they stay pairable for longest. Tiles in the middle of a solid block can reach nothing at all.
• Open lanes, don't just clear pairs. A match that punches a hole through the middle of a long row is worth more than a match at the edge that changes nothing.
• Count the copies. When all four of a tile are still on the board you have six possible pairings; when two are left you have one. Spend the plentiful tiles freely and protect the last pair of anything.
• Watch for tiles with one route left. If a pair can only be joined through a single lane, clear it before something closes that lane — or before you close it yourself.
• Trace the line before you tap. Two identical tiles staring at each other across the board are not necessarily a move. Follow the empty cells with your eye and count the corners.
• Use Shuffle as a rescue, not a habit. A long look usually turns up a route around the outside that you had written off.

Mahjong Connect vs Mahjong Solitaire

The two games share a tile set and almost nothing else. In Mahjong Solitaire the 144 tiles are stacked into a layered pyramid and a tile is playable when nothing sits on top of it and one long side is clear — you are excavating. In Mahjong Connect every tile is visible from the first second, and the difficulty is entirely about geometry: which pairs can still see each other, and how many corners it takes to get there.

If you want the same tiles at a quicker pace, the slot-bar spin of Tile Mahjong is a third take on them. Prefer cards? Try Pyramid Solitaire. All free, all in the browser, nothing to download.

Board sizes and playing on a phone

Three board sizes ship with the game — Easy (10×6, 60 tiles), Medium (12×7, 84 tiles) and Hard (14×8, 112 tiles). Bigger boards are not just longer; more tiles means fewer empty cells, which means fewer legal routes early on, so they genuinely play harder.

On a phone held upright the grid is turned on its side — a 12×7 board is drawn 7 tiles across and 12 down — so the tiles stay large enough to tap comfortably instead of shrinking to squeeze twelve columns onto a narrow screen. Turning the board changes nothing about the puzzle: every route that existed still exists, rotated with it.
