Mahjong vs Rummikub: What's the Difference?
Quick answer: Mahjong and Rummikub are both rummy-style tile games where you collect tiles on a rack and build them into groups, but they play very differently. Classic Rummikub uses 106 number tiles (1 to 13 in four colors, plus 2 jokers) for 2 to 4 players, and the first player to empty their rack wins. American mahjong uses 152 tiles (three suits, Winds, Dragons, Flowers and 8 jokers), is usually played by four, and you win by completing a 14-tile hand from the current National Mah Jongg League (NMJL) card. Rummikub is quicker to learn; mahjong adds the Charleston, calling discards and a new card every year.
If your group loves Rummikub and keeps hearing about mahjong night, this side-by-side guide explains what carries over, what doesn't, and what you need to make the switch. For the rules in order, see our step-by-step beginner's guide to American mahjong.
Mahjong vs Rummikub at a Glance
| American mahjong | Rummikub (classic) | |
|---|---|---|
| Tiles | 152 in play: 108 suit tiles, 16 Winds, 12 Dragons, 8 Flowers, 8 jokers | 106: numbers 1 to 13 in four colors (two of each) plus 2 jokers |
| Players | Four is standard; two- and three-player versions exist | 2 to 4 |
| Starting tiles | 13 each (East, the dealer, takes 14) | 14 each |
| Goal | Complete one 14-tile hand shown on this year's NMJL card | Be the first to play every tile off your rack |
| Table play | Draw, then discard; call discards to expose groups | Lay down sets and rearrange tiles already on the table; no discards |
| Jokers | 8; only in groups of three or more, never in a single or pair | 2; can stand in for any tile in a set or run |
| Opening | The Charleston, a tile-passing ritual, before play begins | No passing; your first meld must total at least 30 points |
| Scoring | Hand value from the card; losers pay the winner | Losers count the tiles left on their racks |
What Is Rummikub?
Rummikub was created by Ephraim Hertzano, who hand-made the first sets with his family, and it won Germany's Spiel des Jahres (Game of the Year) award in 1980. It is usually described as combining elements of rummy and mahjong. A classic box has 104 number tiles valued 1 to 13 in four colors, two of each, plus two jokers. Some designer "rummi" sets add extra jokers or blanks, so check your box.
Each player starts with 14 tiles. Your first play, the initial meld, must come from your own rack and total at least 30 points. After that, you lay down runs (three or more consecutive numbers in one color) and groups (three or four of the same number in different colors), or rework sets already on the table. If you don't play, you draw a tile. The first player to empty their rack wins.
What Is American Mahjong?
Mahjong began in China in the 19th century and swept the United States in the 1920s. American mahjong follows the National Mah Jongg League, founded in 1937, which publishes a new card of winning hands every year. A standard set has 152 tiles in play: three suits (Bams, Craks and Dots) numbered 1 to 9 with four of each, 16 Winds, 12 Dragons, 8 Flowers and 8 jokers. Our guide to how many tiles are in an American mahjong set explains why many sets come with 160.
Everyone starts with 13 tiles (East takes 14). After the Charleston, players take turns drawing a tile and discarding one, aiming to match one of the hands on the card exactly. Our walkthrough of the NMJL card explains how to read it.
How Mahjong and Rummikub Are Alike
- Both are rummy-family games: you collect tiles and build them into groups and number patterns.
- Both use racks, so only you can see your tiles.
- Both have jokers, and in both a joker on the table can be won back by swapping in the real tile it represents.
The Key Differences
1. The tiles
Rummikub tiles carry only a number and a color; mahjong adds suits, Winds, Dragons, Flowers and jokers. For example, our Amber Tortoiseshell American mahjong set lists its 160 tiles as 36 Dots, 36 Bams, 36 Cracks, 12 Dragons, 16 Winds, 8 Flowers, 8 Jokers and 8 blank spares. Mahjong suits run 1 to 9, not 1 to 13, and the White Dragon (nicknamed "Soap") can stand in as a zero on some card hands.
2. Groups mean different things
In Rummikub, a group is the same number in different colors, such as a red 7, blue 7 and black 7. In mahjong, a group is made of identical tiles: a pung is three of the same tile, a kong is four, and American mahjong adds the quint (five) and sextet (six), which usually need jokers. Number runs appear on the card as patterns, but American mahjong doesn't let you call a discard to complete a straight run; you can call only for a pung, kong, quint or sextet, or for the tile that gives you Mah Jongg.
3. Your rack vs. the shared table
Rummikub's signature move is rearranging the table: you can split a run, extend any set or borrow a tile, as long as everything is valid when your turn ends. Mahjong has no shared melds. When you call a discard, you expose that group on top of your rack and it stays yours. The one thing other players may take from your exposure is a joker, by swapping in the real tile on their turn.
4. Jokers work differently
A Rummikub joker can stand in for any tile in any set. A mahjong joker can only be used in a pung, kong, quint or sextet, never as a single tile or in a pair, and a joker that is discarded is dead. The joker exchange lets you take a joker from any exposed group, including your own, by replacing it with the matching tile on your turn. Our mahjong jokers guide covers every rule.
5. Discards and calling
Rummikub has no discards: each turn you play tiles or draw one. In mahjong, every turn ends with a discard, and any player who needs that tile for an exposure or for Mah Jongg can call it, even out of turn. So mahjong is a game of defense as well as offense.
6. The Charleston
American mahjong opens with the Charleston: players pass three tiles at a time to the right, across and to the left to improve their hands. There is nothing like it in Rummikub. Our Charleston strategy guide shows what to keep and what to pass.
7. Winning and scoring
Rummikub is a race to empty your rack, and the losers count the value of the tiles they still hold (a leftover joker costs 30 points). In mahjong, you declare "Mah Jongg" when your 14 tiles match a card hand, and the other players pay the hand's value (whoever threw the winning discard pays double).

Is Mahjong Harder Than Rummikub?
At first, yes. Rummikub needs only two set types and a 30-point opening rule, so most families are playing within a few rounds. Mahjong asks you to learn more tile types, the Charleston, calling, joker rules and a card that changes every year. The trade-off is variety: a new card each year keeps mahjong fresh for longtime players, while Rummikub's challenge comes from spotting table rearrangements on every turn. Many groups happily play both.
Tips for Rummikub Players Learning Mahjong
- Stop thinking "empty the rack." You keep 13 tiles and build toward one hand on the card.
- Pick two or three target hands early, use the Charleston to steer toward them, then narrow to one.
- Watch your discards; they can hand someone else the game.
- Learn the lingo. Our American mahjong glossary explains pung, kong, Soap, NEWS and more.
- Short on players? Rummikub works with two; mahjong can too, with adjusted rules. See how to play American mahjong with 2 or 3 players.
What You Need to Switch From Rummikub to Mahjong
A Rummikub box won't work for mahjong (see the FAQ below). Here's what a mahjong table needs.
An American mahjong tile set
Choose a set made for American play, with jokers, Flowers and easy-read Western numerals. A few picks from our mahjong sets collection:
- Champagne Shell: 160 acrylic tiles with champagne-gold shell-flake backs, botanical faces and easy-read Western numerals (tiles only).
- Bloom Garden: 160 acrylic tiles in a lavender-and-lime floral design, with 4 pushers and a luxury storage case included.
- Amber Tortoiseshell: 160 lightweight single-layer tiles (152 game tiles plus 8 spares) with an amber tortoiseshell look.
Racks and pushers
Mahjong racks hold a longer row of tiles, and many come with pushers that slide your section of the wall toward the center of the table. Our Translucent Pastel 18" racks come as a set of 4 with integrated pushers in a choice of colors, and the Clear Acrylic racks are a set of 4 with attached pushers, about 18.5" long. Browse more in mahjong racks.
The NMJL card
Every player needs the current card from the National Mah Jongg League. It lists the year's winning hands and is sold by the League, separately from tile sets.
A mat (optional, but nice)
A mat cushions shuffling and keeps tiles in place. The Hunter Green Daffodil mat is 33" x 33" neoprene with a non-slip backing and an instructional layout printed on the mat to help keep the Charleston organized. See every design in mahjong mats, or start with a bundle from our starter kits.
Frequently Asked Questions
Is Rummikub similar to mahjong?
Yes, in some ways. Both are rummy-style tile games where you keep tiles on a rack, build groups and use jokers. The big differences are the goal and the tiles: Rummikub is a race to empty your rack using numbered tiles in four colors, while American mahjong is about completing one hand from the NMJL card using suits, Winds, Dragons, Flowers and jokers.
Is mahjong harder than Rummikub?
Mahjong is harder to learn. Rummikub has two set types and one opening rule, while American mahjong adds more tile types, the Charleston, calling discards, joker rules and a new card every year. Many players find mahjong's extra depth is what keeps them coming back.
Can you play mahjong with Rummikub tiles?
No. A Rummikub set has numbered tiles in four colors and two jokers, but no Bams, Craks, Dots, Winds, Dragons or Flowers. American mahjong needs a full set of 152 tiles, including 8 jokers.
How many tiles are in Rummikub compared with mahjong?
Classic Rummikub has 106 tiles: 104 numbered tiles and 2 jokers. American mahjong uses 152 tiles, including 8 jokers and 8 Flowers. Many American sets include 160 tiles; the extras are spares, usually blanks.
Is mahjong like rummy?
Mahjong is often compared to rummy because you draw and discard to build matching groups. American mahjong adds tile types that rummy doesn't have, the Charleston, and a yearly card of set hands you must match exactly to win.
How many people do you need to play mahjong vs Rummikub?
Rummikub is played by 2 to 4 players. American mahjong is designed for four, though two- and three-player versions exist with adjusted rules.
