152 vs 166: What's the Difference?
You'll often see both numbers mentioned. Here's the distinction: 152 tiles are the standard NMJL playing set (Bams + Dots + Craks + Winds + Dragons + Flowers + Jokers = 152). The additional 14 tiles in a 166-tile set are extras: 8 Season tiles, 2 spare Jokers, and 4 blank replacement tiles. These extras aren't used in standard play but are included for completeness and as spares.
How Does This Compare to Other Variants?
| Variant | Tile Count | Key Difference |
|---|---|---|
| American (NMJL) | 166 | Includes 8 Jokers + extras |
| Chinese (MCR) | 144 | No Jokers; has Flowers + Seasons |
| Japanese (Riichi) | 136 | No Jokers, Flowers, or Seasons |
| Hong Kong | 144 | Similar to Chinese, no Jokers |
