Hi Oliver! Thank you for creating this game. It has brought my friends and I many hours of fun during quarantine. :) We're wondering if there's any chance you would consider adding the Hong Kong Old Style Scoring Variation 3? That is the style we learned from our parents in Hong Kong and is the style we are most familiar with. We would appreciate it very much. Thank you! http://mahjong.wikidot.com/rules:hong-kong-old-style-scoring -Fish
