## Description

Enter 14 tiles and compare every discard by shanten, improving-tile variety, and tiles remaining—all calculated on your device.

Mahjong Shanten Calculator compares every possible discard from a 14-tile Japanese mahjong hand.

See which discard keeps the lowest shanten number, which tiles improve the hand next, and how many copies of those tiles remain.

FEATURES

• Enter characters, circles, bamboo, and honor tiles with a tap
• Compare all discard candidates with the best shanten number
• View improving-tile types and the total number of copies remaining
• Evaluate standard hands, seven pairs, and thirteen orphans together
• Calculate instantly and entirely on your device

USE IT TO

• Review alternative discards after a game
• Check the ukeire for a mahjong puzzle
• Compare a standard-hand route with seven pairs
• Practice tile efficiency as a Japanese mahjong learner

No account, ads, analytics, or network connection is required.

Improving tiles are calculated from the 14 tiles in your hand only. Visible discards, called tiles, yaku, score, turn number, safety, and other players' hands are not considered. Use the results as a tile-efficiency study aid rather than a complete in-game decision.
