Haneman

Haneman

Haneman (跳満, はねまん) is a scoring level in mahjong worth either 8-10 han or a fixed 12,000 basic points for non-dealer hands and 18,000 basic points for dealer hands. It represents a significant jump in hand value, positioned between mangan and baiman on the scoring hierarchy.

Detailed Explanation

Haneman occupies a crucial position in mahjong’s point system. The term literally translates to “jumping full,” reflecting how this score represents a substantial increase from standard han-based calculations.

Scoring Structure

A haneman hand yields:

• Non-dealer (Ko): 12,000 basic points, which translates to 12,000 points from the discarder, or 4,000-8,000 points distributed among other players depending on who discarded
• Dealer (Oya): 18,000 basic points, paid entirely by the discarder

These fixed values apply regardless of the exact tile composition, similar to mangan and other limit hands.

Position in the Scoring Hierarchy

Haneman sits between two other major scoring levels:

• Below: Baiman (8,000 basic points for non-dealer, 12,000 for dealer)
• Above: Sanbaiman (12,000 basic points for non-dealer, 18,000 for dealer)

The progression from baiman to haneman to sanbaiman represents increasingly prestigious hand accomplishments.

Han Requirements

Technically, haneman encompasses hands worth 8-10 han. However, in practical play, most hands reaching 8 han or higher are scored at their limit value rather than calculated point-by-point. The haneman designation simplifies scoring for particularly strong hands while maintaining the distinction between different achievement levels.

Strategic Significance

Reaching haneman represents a major accomplishment in a single hand. It typically requires either:

• Multiple high-value yaku combinations
• Rare or difficult yaku such as kazoe yakuman components
• Fortunate tile draws that complete expensive patterns

Players often adjust their strategy when they recognize a haneman is possible, as the point swing is substantial enough to significantly impact game standings.

Usage Example

During an East round, the dealer completes a hand with Tanyao, Pinfu, and Toitoi—three yaku totaling 7 han. However, the hand also contains a closed wait, adding one more han for a total of 8 han. Rather than calculating 8 han × 2,000 points per han, the hand is scored as haneman: the discarder pays the dealer 18,000 points.

In another scenario, a non-dealer player wins with a hand containing Honroutou (2 han), Toitoi (2 han), and Shou Sangen (6 han), totaling 10 han. This is scored as haneman: 12,000 points from the discarder.

Related Terms

Baiman - The scoring level below haneman (8,000 basic points non-dealer, 12,000 dealer). Baiman hands are worth 6-7 han and represent a significant but slightly less impressive achievement than haneman.

Sanbaiman - The scoring level above haneman (12,000 basic points non-dealer, 18,000 dealer). Sanbaiman requires 11-12 han or specific yakuman combinations and represents one step below a true yakuman.

Mangan - A foundational limit hand (8,000 basic points non-dealer, 12,000 dealer) worth 5 han. Mangan is the first scoring plateau that uses fixed values rather than han-based calculations.

Han - The individual counting units that comprise a mahjong hand’s value. Haneman requires a minimum of 8 han to achieve.

Agari - The winning condition in mahjong. A player must achieve agari to score their hand, including haneman hands.

Yakuman - A special category of hands worth 13+ han or fixed maximum points, representing the highest possible scores. Sanbaiman and haneman are stepping stones toward yakuman achievement.
