This guide explains the 144 tiles in Mahjong, their categories, material options and how modern manufacturers create customized Mahjong sets for different needs.How Many Tiles Are in a Mahjong Set?A standard mahjong set contains 144 tiles. These tiles are divided into three main groups: suited tiles, honor tiles and bonus tiles. Each group has different tile types and plays a different role in the game.The 108 suited tiles (Dots, Bamboo and Characters) make up the largest part of a Mahjong set and are used for forming regular combinations. The honor tiles, including Winds and Dragons, add additional scoring possibilities, while Flowers and Seasons are bonus tiles included in many traditional Mahjong sets.The Three Suits: 108 Number TilesA standard mahjong set contains 108 suited tiles, which make up the core of Mahjong gameplay. These tiles are divided into three suits: Dots, Bamboo and Characters.Each suit follows a simple numbering system from 1 to 9, with four copies of every tile. Together, these three groups create the main combinations used during a Mahjong game, including sequences and matching sets.1.Dots (Circles)Dots, also known as Circles, are recognized by the round symbols printed on the surface of each tile. The circular patterns are traditionally linked to coins, which is why this suit is often associated with wealth and prosperity in Mahjong culture.The Dots suit includes numbers from 1 to 9, with four versions of each tile, making 36 tiles in a complete set. Because of their clear visual patterns, Dots are usually one of the easiest suits for new players to identify.Beyond gameplay, the simple geometric appearance of Dots tiles also makes them popular in Mahjong designs with a modern or artistic style.2.Bamboo (Bams)Bamboo tiles represent one of the three numbered suits and feature bamboo-inspired patterns. The suit follows the same structure as Dots, covering numbers 1 through 9 with four copies of each tile.A complete Bamboo suit contains 36 tiles. Among them, the 1 Bamboo tile is often the most recognizable because many traditional designs include a bird illustration instead of the usual bamboo pattern.The combination of natural imagery and traditional symbolism gives Bamboo tiles a distinctive appearance within a mahjong set.3.Characters (Craks)Characters, also called Craks, use Chinese characters to represent numbers from 1 to 9. Unlike the visual patterns of Dots and Bamboo, this suit highlights the written symbols that are closely connected with traditional Chinese culture.There are 36 Character tiles in this group, following the same four-copy structure as the other numbered suits. Their traditional script design gives them a classic appearance and makes them an important part of the overall Mahjong aesthetic.Together, Dots, Bamboo and Characters form the complete set of 108 suited tiles used in Mahjong.Honor Tiles: Winds and DragonsIn addition to the numbered suits, a complete mahjong set also includes 28 honor tiles. These tiles are different from suited tiles because they do not represent numbers or follow a sequence.Honor tiles are divided into two groups: Winds and Dragons. They play an important role in Mahjong combinations while also adding symbolic elements to the design of the tiles.1.Wind TilesWind tiles represent the four directions used in Mahjong: East, South, West and North.There are 16 Wind tiles in a complete set, with four copies of each direction. These tiles are closely connected with player positions and scoring rules, making them an important part of Mahjong strategy.Their simple directional symbols also make Wind tiles easy to recognize, even for beginners who are still learning the different tile categories.2.Dragon TilesDragon tiles are another group of honor tiles and include three types: Red Dragon, Green Dragon and White Dragon.Each Dragon type appears four times, creating 12 Dragon tiles in total. Unlike numbered tiles, Dragons are not arranged into sequences but are used as special combinations during gameplay.With their distinct symbols and color differences, Dragon tiles add both strategic value and visual variety to a Mahjong set.Bonus Tiles: Flowers and SeasonsMany traditional Mahjong sets include 8 bonus tiles, which are divided into Flower tiles and Season tiles. Unlike the main numbered and honor tiles, these tiles are not used in every Mahjong variation but are commonly included in complete traditional sets.Beyond their gameplay purpose, bonus tiles often feature more detailed illustrations and decorative designs, making them especially popular in collectible and artistic Mahjong sets.1.Flower TilesFlower tiles represent four traditional flowers: Plum, Orchid, Bamboo and Chrysanthemum.Each flower is represented by one tile, creating 4 Flower tiles in a complete set. These tiles often include detailed artwork and cultural meanings, adding decorative value beyond their gameplay function.Because of their visual appeal, Flower tiles are often among the most attractive elements in specially designed mahjong sets.2.Season TilesSeason tiles represent the four seasons: Spring, Summer, Autumn and Winter.Similar to Flower tiles, each season appears once, creating 4 Season tiles. Their designs usually reflect seasonal themes and traditional imagery, adding more variety to the overall appearance of Mahjong tiles.Do All Mahjong Sets Have 144 Tiles?Not every mahjong set contains the same number of tiles. A traditional Chinese mahjong set usually includes 144 tiles, but different Mahjong variations may use fewer or additional tiles depending on their regional rules.The main differences come from the use of bonus tiles and special tiles. For example, Japanese Riichi Mahjong usually removes flower and season tiles, while American Mahjong adds joker tiles as part of its gameplay system.Understanding these differences helps players choose a mahjong set that matches the Mahjong style they want to learn or play.What Are Mahjong Tiles Made Of?Mahjong tiles have been produced using different materials as manufacturing methods have changed over time. Early Mahjong sets were often made from natural materials, while modern tiles are commonly produced with materials such as plastic, resin and acrylic.The choice of material influences the overall characteristics of a Mahjong set, including its weight, durability, surface texture and visual appearance.1.Traditional Mahjong Tile MaterialsEarly Mahjong tiles were typically made from combinations of bamboo and bone. These materials gave traditional sets a distinctive texture and were often associated with handcrafted production methods.As Mahjong became more widely played, manufacturers began using plastic materials to improve production efficiency and consistency. Plastic and resin tiles are now commonly found in many standard Mahjong sets because they are practical and suitable for large-scale manufacturing.2.Acrylic Mahjong TilesAcrylic mahjong tiles are a modern option that provides a different look and feel from traditional materials. The material is valued for its clarity, smooth surface and ability to support various visual effects.Compared with conventional plastic tiles, acrylic allows more flexibility in creating contemporary Mahjong styles, including transparent designs, layered appearances and different color expressions.For modern Mahjong collections that focus on design and presentation, acrylic provides a material choice that combines durability with greater visual possibilities.Create Your Custom Acrylic Mahjong SetA custom mahjong set gives brands and businesses the opportunity to create Mahjong products based on their own requirements, from the initial concept to the final production details.At Symphony Acrylic, we focus on acrylic Mahjong manufacturing and provide OEM solutions for different types of projects.

At first glance, a Mahjong set can seem difficult to read. Some tiles are covered with circles, others show bamboo-like lines, and several use Chinese characters that may be unfamiliar to new players. Once the tiles are divided into their main groups, however, the system becomes much easier to understand.For related buying, design and care guidance, visit the Symphony Acrylic Mahjong blog library.The symbols communicate the suit, numerical value or special role of each tile. Most traditional sets contain three numbered suits, four Winds and three Dragons. Depending on the regional rules, the set may also include Flowers, Seasons, Jokers or blank replacement tiles.Tile groupCommon appearancePrimary functionDots or CirclesOne to nine circular symbolsNumbered suitBamboo or BamsOne to nine bamboo-like formsNumbered suitCharacters or CraksChinese numbers and 萬Numbered suitWinds東, 南, 西 and 北Honor tiles representing four directionsDragons中, 發 and a blank or framed symbolHonor tiles used in scoring patternsFlowers and SeasonsPlants or seasonal imagesBonus tiles in selected variantsJokers“Joker” text or distinctive artworkWild tiles used primarily in American MahjongHow to Recognize Symbols on Acrylic Mahjong TilesThe simplest method is to recognize the group before reading the exact value. Circles belong to Dots. Repeated stalk-like marks belong to Bamboo. Chinese numerals paired with 萬 belong to Characters.Winds and Dragons require more familiarity because they do not form a numerical sequence. New players often learn these seven honor tiles by shape and position. American mahjong tiles may add English letters or Arabic numbers in the corners, making the traditional symbols easier to recognize.This process matters when a set uses decorative artwork. Unusual colors, transparent layers and themed illustrations can give custom acrylic mahjong tiles a strong identity, but the underlying value must remain clear at normal playing distance.Color should support recognition rather than carry it alone. Players with color-vision differences may struggle when categories share similar shapes and differ only in red or green. Strong contrast, consistent placement and distinct outlines make a set more accessible.The Three Numbered Suits in Chinese Mahjong TilesThe numbered section contains Dots, Bamboo and Characters. Each suit runs from One to Nine, with four copies of each value. This produces 108 suited tiles altogether.Dots or CirclesThe Dot suit uses circular symbols arranged in recognizable patterns. The circles are historically associated with coins, reflecting Mahjong’s connection with earlier Chinese money-suited playing cards.One Dot often contains a single large decorative circle. Higher values use repeated circles arranged so players can recognize them without slowly counting every mark. A custom version may change the internal illustration or palette, but the quantity and arrangement should remain visible.Bamboo or BamsThe Bamboo suit uses repeated line forms associated with bamboo stalks or strings of coins. Tiles Two through Nine generally display the corresponding number of forms.One Bamboo is the familiar exception. It frequently features a bird, which may resemble a sparrow, peacock or another species. This freedom makes One Bamboo a natural place for original artwork, provided it remains connected to the suit and cannot be mistaken for a Flower.Characters or CraksCharacter tiles display a Chinese number together with 萬, meaning “ten thousand.” American players often call the suit Craks, an abbreviation of Characters.For players who do not read Chinese, a small Arabic number is useful. It preserves the traditional character while making the tile faster to identify. The index should support the main symbol rather than dominate the composition or disappear into a decorative background.Winds and Dragons in an Acrylic Mahjong SetWinds and Dragons are collectively known as honor tiles. They have no numerical sequence but play important roles in hand formation and scoring under many rules.The four Winds are East 東, South 南, West 西 and North 北. They may relate to a player’s seat, the current round or particular scoring combinations. Their exact use changes between Mahjong versions, so beginners should learn the symbols before attempting to memorize every scoring condition.The Dragons are Red, Green and White. Red commonly displays 中, meaning “center” or “middle.” Green usually displays 發, a character associated with development or prosperity. White may be shown as an empty frame or a blank face.That blank White Dragon is easily confused with a spare tile. Inspect the complete assortment: four matching blank tiles placed with the honor group are likely White Dragons, while replacements are usually separated or supplied in smaller quantities.Reflective acrylic can make fine strokes harder to see under concentrated lighting. Honor tiles therefore benefit from bold lines, comfortable spacing and strong contrast.Flowers, Seasons and American Mahjong TilesFlower and Season tiles allow greater artistic variation. A traditional group often contains Plum, Orchid, Chrysanthemum and Bamboo alongside Spring, Summer, Autumn and Winter.The World Mahjong Organization’s competition rules describe a 144-tile set containing eight Flower tiles. Other Mahjong versions may exclude Flowers or treat them differently when drawn. Tile count alone therefore does not always reveal the intended style of play.American mahjong tiles also use Flowers and normally include Jokers. A Joker may substitute within eligible groupings according to the applicable rules or card. This variation has a practical consequence for product development: the target market must be decided before artwork and set configuration are finalized.Attractive Flower illustrations cannot compensate for the wrong quantity of Jokers, missing indices or unsuitable accessories. Play format is part of the product specification.Designing Custom Mahjong Tiles Without Losing MeaningSuccessful custom mahjong tiles feel original without forcing players to relearn the visual system. Creativity works best when it rests on consistent rules.Before illustrating individual faces, establish number placement, corner indices, line thickness, color contrast and repeated borders. Test artwork at the physical tile size. Details that look clean on a monitor may close up during engraving or disappear after reduction.Transparent acrylic creates another challenge because the table, rack and surrounding colors remain visible through the tile. A backing layer, deeper engraving or carefully selected fill can preserve contrast.At Symphony Acrylic, engraving, printing, color filling, custom backs and multilayer construction for acrylic Mahjong tiles can be matched to the artwork rather than applied as a standard recipe. Bold symbols may suit engraving; detailed multicolor illustrations may require printing. Precision processing and controlled finishing then help the full set align, stack and read consistently.The final review should take place at three distances: close enough to assess production, at normal hand distance and across the table. A tile design succeeds only when it works in all three contexts.FAQ About Mahjong Tile SymbolsAre all blank Mahjong tiles White Dragons?No. Blank-looking pieces may be White Dragons, replacements or optional house-rule tiles. Their quantity and position in the complete set usually reveal their purpose.Why do symbols differ between sets?Regional conventions, manufacturing methods and artistic preferences influence Birds, Flowers, Dragons and indices. Their gameplay categories can remain the same even when the illustrations change.Can traditional symbols be replaced with branded artwork?Yes, provided suit and value remain immediately recognizable. Logos, fonts and illustrations should also be original or properly licensed for commercial use.Do American Mahjong tiles need English indices?They are not what makes a physical tile playable, but they improve access for players who cannot read Chinese characters and are valuable for beginner or retail sets.Can every tile carry a logo on its back?Yes, if placement, color and finish remain consistent. No tile should contain a visible difference that identifies it while face down.Authoritative ReferencesWorld Mahjong Organization — Mahjong Competition RulesThe Unicode Standard — Mahjong TilesStanford University — How Mahjong Shaped Modern AmericaUniversity of Pennsylvania Museum — Historic Mahjong Tile SetDevelop a Recognizable Custom Acrylic Mahjong SetDistinctive artwork should make a set more memorable, not more difficult to play.
