Playing with my bot friends has increased my play speed and decision-making abilities. Besides the AI suggestions, I use the League card to pivot if necessary. I have played the last 4 weeks with humans who are very patient with beginners. My speed with the bots has dropped from 30 minutes per game to 15. Staying focused is the key. Really love this challenge.

Finally, a computer version that's the actual real game of American Mahjong. Wish there was a button for calling a tile.
