ShuffleSimMajhong

ShuffleSim Mahjong is a single-purpose offline utility for officiating teams who need to verify that the pre-game shuffle on a competitive mahjong table actually meets tournament uniformity requirements.

Built-in models simulate common procedures: Four-Stack Shuffle, Eight-Pass Cross Shuffle, Spread + Rotate, Random-Draw Reinsertion, Overhand + Cross, and the championship-grade Ultra-Mix 12-Step Protocol.

Workflow: pick a method, follow the step-by-step animation at the table, then log what was actually performed via the Recorder. The Analyser converts the recorded sequence into a 0–100 uniformity score with per-stage breakdown, suit-distribution diagnostics, and concrete suggestions when the score is below your tournament threshold.

Results can be previewed as a fully formatted PDF and shared with adjudicators. Sessions are stored in History for post-match audit.

Privacy / scope notes: This tool is strictly a fairness aid. It does NOT involve real money, in-app purchases, gambling, slot mechanics, or networked play. No telemetry is collected; no data leaves the device.

Tile glyphs are drawn from the Unicode Mahjong Tiles block (U+1F000–U+1F02B). The Tile Library screen lists all 144 wall tiles with English names and pinyin annotations.
