Mahjong: What It Is and How to Play
Mahjong is two different games sharing one name. If you want a quick, solo browser game, you mean mahjong solitaire — a tile-matching puzzle where you clear a stacked layout by pairing identical tiles. If you want the classic table game, you mean traditional mahjong — a four-player game of drawing and discarding tiles to build winning hands. Both are available to play free online at 247 Games, which lists Mahjong among its game categories alongside Solitaire, Sudoku, and FreeCell.
The two games behind the name
| Mahjong solitaire | Traditional mahjong | |
|---|---|---|
| Players | One | Usually four |
| Goal | Remove every tile from the layout | Complete a valid winning hand before opponents |
| Core action | Match identical free tiles | Draw, discard, and claim tiles to form sets |
| Luck vs. skill | Mostly puzzle-solving, some layout luck | Mixed: tile draws plus reading opponents |
| Typical session | A few minutes to one sitting | Multiple rounds per game |
Knowing which one you want saves time, because the rules and skills barely overlap.
Mahjong solitaire: how to start playing
This is the version most people meet first online. The goal is simple: clear the board by removing tiles in identical pairs.
The basic flow
- Look at the layout. Tiles are stacked in layers, often in a turtle or pyramid shape. Only some tiles are available at any moment.
- Find a "free" tile. A tile is free when nothing rests on top of it and at least one of its long sides is open — not blocked by a neighboring tile.
- Match it with an identical free tile. Pairs are usually exact matches (two identical tiles), though some layouts use matching categories instead.
- Remove the pair. The two tiles disappear, which can free up tiles underneath.
- Repeat until the board is empty — or you get stuck.
What to watch for
- Free tiles only. A tile buried under others or boxed in on both sides can't be selected, even if its match is visible.
- Order matters. Removing a pair in one order can open the board; the same pairs in another order can dead-end you.
- Plan a few moves ahead. When several matches are available, prefer the one that unlocks the most new tiles.
- Stuck is normal. Many layouts can become unsolvable partway through. Restarting or using a hint is part of the game, not a failure.
Verify you're playing correctly
If tiles won't select, check whether the tile is actually free — that's the most common confusion. If the board clears, you've won. If no legal pairs remain and tiles are left, the layout is blocked and you'll need to restart or reshuffle.
Traditional mahjong: the goal and structure
Traditional mahjong is a rummy-like game for a table of players. The exact tile set and scoring vary by region, but the shared structure is consistent.
The goal
Build a complete hand — typically four sets plus a pair. A set is either three or four identical tiles, or three consecutive tiles of the same suit. The pair is two identical tiles. First player to complete a valid hand and declare it wins the round.
The basic flow
- Set up. Tiles are shuffled and each player builds a wall or receives a starting hand, depending on the variant.
- Take turns. On your turn you draw a tile, then discard one.
- Form sets. You keep tiles that build toward your sets and pair, and discard the rest.
- Claim discards (in many variants). You can take a tile another player discards if it completes a set, which speeds up your hand.
- Declare a win. When your hand is complete, you reveal it. Scoring and payment follow the variant's rules.
Common tile types
- Suits — three numbered suits (often called characters, bamboo, and dots), each running 1 through 9 in four copies.
- Honor tiles — winds and dragons, which can't form runs but can form identical sets.
- Bonus tiles — flowers and seasons in many sets, handled by special rules.
Because regional rules differ, learn the specific variant your group or app uses before your first game.
Which one should you play?
- Choose mahjong solitaire if you want a solo, low-pressure puzzle you can finish in one sitting and play in a browser without learning complex rules.
- Choose traditional mahjong if you want a social, strategic table game and are willing to learn a rule set and play with others.
You don't have to pick permanently — the two scratch different itches, and both are easy to try.
