Slightly modified of my old score sheet. I removed my modified payout variant since I never used it, and I added some highlighting to note the common scoring opportunities. You could easily play HKMJ with just the highlighted scoring sets.
A cheat sheet with numbers and winds as well as scoring for HK old style Mah Jong Scoring. Includes a proposed alternate (simplified) payout system.
