For new work this Mahjong needs some work on the Undo and Show Matches Button 1. If I hit show Matches then Shuffle the wrong pieces are flashing, just turn off show matches after shuffles is clicked 2. If show matches is clicked turn it off after 5 seconds 3. Test and make sure any combination of those buttons can be hit and not cause issues
