Simple Tiles
The numbered tiles from 2 through 8 in each suit. Simple tiles sit in the middle of the number range, giving them the most flexibility for building sequences and consecutive-number hands.
What Are Simple Tiles?
Simple tiles are the 2 through 8 of each of the three suits, Bam, Crak, and Dot. The name "simples" comes from traditional Mahjong terminology and distinguishes these middle-range tiles from terminal tiles (1s and 9s) and honor tiles (Winds and Dragons).
There are 7 numbers of simple tiles in each suit (2, 3, 4, 5, 6, 7, 8), and with 3 suits and 4 copies of each, the set contains 84 simple tiles total. That means simples make up roughly half of all 166 tiles in a standard American Mahjong set, by far the largest category.
The defining characteristic of simple tiles is their positional flexibility. A tile like 5 Bam can participate in multiple consecutive sequences: 3-4-5, 4-5-6, or 5-6-7. Compare this to a terminal tile like 1 Bam, which can only appear in a 1-2-3 sequence, or a 9 Bam, limited to 7-8-9. This flexibility makes simples the most versatile numbered tiles in the game.
In traditional Chinese and Japanese Mahjong, the distinction between simples and terminals has direct scoring implications. Certain winning patterns reward or penalize the presence of terminal and honor tiles. While American Mahjong under the NMJL does not use these scoring categories directly, the underlying strategic difference remains: simple tiles are more flexible, more commonly needed, and therefore more hotly contested.
Simples on the NMJL Card
On the NMJL card, simple tiles appear throughout virtually every hand category. They are shown as numbers 2 through 8 in the standard suit colors, blue/green for Bam, red for Crak, and black for Dot.
Simple tiles are the workhorses of the card. Most hands involve at least some simple tiles, whether in pairs, Pungs, Kongs, consecutive runs, or other groupings. Their prevalence on the card reflects their abundance in the tile set.
### Why Simples Are Strategically Important
Higher demand means higher competition. Because so many hands use simple tiles, multiple players at the table often need the same mid-range numbers. A 5 Crak might be useful for several different hands, while a 1 Crak or 9 Crak applies to fewer patterns. This means simple tiles are less likely to appear in discards, players tend to hold onto them longer.
Consecutive-number hands love simples. Hands requiring runs of consecutive numbers (like 2-3-4 or 5-6-7) are built almost entirely from simple tiles. Only the sequences that touch the edges (1-2-3 and 7-8-9) involve terminals. If you are pursuing a consecutive-number hand, your focus will be squarely on simples.
Simples during the Charleston. Because simple tiles are so widely useful, players are more reluctant to pass them during the Charleston. Receiving simples in the Charleston is common (since everyone has them) but getting the specific simples you need is not guaranteed. Passing simples away is a stronger commitment signal than passing terminals or honor tiles, it tells observant opponents you are unlikely to need that particular suit-number combination.
Defensive awareness. Discarding simple tiles mid-game carries more risk than discarding terminals or honors. The more central a tile is to the number range, the more hands it potentially fits into. A 5 in any suit is statistically more likely to be useful to an opponent than a 1 or 9. Advanced players weigh this risk when deciding what to discard, especially in the later stages of a hand when other players may be close to Mah Jongg.
Tracking simples. With 84 simple tiles in the set, exhaustive counting is harder than tracking honors (28 tiles) or terminals (24 tiles). However, tracking specific simples you need, say, how many 6 Dots remain, follows the same logic: 4 copies exist, subtract what you see in discards and exposures, and you know what is left.
Simples vs. Terminals vs. Honors
Understanding the three tile categories, simples, terminals, and honors, gives you a framework for evaluating tile value and risk throughout a game of American Mahjong.
- Simple tiles (2-8): Most flexible, most abundant, highest demand, riskier to discard late in the game
- Terminal tiles (1s and 9s): Less flexible, moderate demand, generally safer to discard
- Honor tiles (Winds and Dragons): No sequence capability, specialized demand, often safest to discard unless an opponent is building honor-based hands
This hierarchy is not absolute, the current year's NMJL card can shift the relative value of any tile category. A card heavy on terminal-based or honor-based hands changes the calculus. But as a general principle, simple tiles are the most contested and therefore demand the most strategic attention.
New players often undervalue the distinction between simples and terminals, treating all numbered tiles equally. As your game improves, developing an instinct for which tiles are "hot" (likely needed by opponents) and which are "cold" (safer to discard) will sharpen your defensive play considerably. Simples, especially those in the 4-6 range, tend to run hotter than tiles at the edges.
