Match two identical tiles. Watch them lift off the board. Keep going until the board is clear. That is the whole game — and it is the reason people have been playing mahjong solitaire for decades.

Double Mahjong is a free mahjong game built around two things most tile games get wrong: tiles big enough to actually see, and a pace you set yourself.

MATCH TWO TILES, NOT THREE
A lot of newer tile match games ask you to collect three tiles into a tray, and lose you the level when the tray fills up. This is not that game. Double Mahjong is classic mahjong solitaire on an open board — you match two identical tiles at a time, and there is no tray, no fail state waiting to surprise you.

HOW TO PLAY MAHJONG SOLITAIRE
Tap or slide two matching mahjong tiles to remove them from the board. A tile can only be matched when it is free — not covered by another tile, and open on its left or right side. Clear every tile and the board is solved.

The rules take thirty seconds to learn. The puzzles will keep you thinking for years. If you have ever played majong, mahjongg, or what some people call Shanghai solitaire, you already know exactly what to do.

BIG TILES, FOR EYES THAT ARE TIRED OF SQUINTING
• Extra-large mahjong tiles with high-contrast, easy-to-read symbols
• Big, clear text and buttons everywhere in the game — not just on the board
• Soft, low-glare backgrounds that stay comfortable late at night
• Generous tap targets, so you never lose a match to a mis-tap
• Looks right on both phones and tablets

This is a mahjong game for adults and seniors who want to enjoy a puzzle without reaching for their glasses.

A QUIET KIND OF MENTAL EXERCISE
Scanning the board for pairs, deciding which layer to open next, weighing which of two matches to take — mahjong solitaire keeps your mind pleasantly occupied without ever feeling like work. Plenty of players make it part of a morning routine with coffee, or a wind-down before bed. It is a brain game in the nicest sense: absorbing, unhurried, and entirely up to you.

ABOUT THE NAME
Mahjong solitaire is also known as Shanghai solitaire, and is played with the tile set of the classic Chinese game of mahjong. You will see it spelled majong, mahjongg, mah jong or even mahjong solitare — they all refer to the same tile matching puzzle. Please note this is the single-player version. It is not the four-player game with draws, discards and winning hands.

Find your first pair. Let the board come apart one match at a time.
