>>> TRICKS AND TIPS
-------------------
When the notice of 'Three Tiles Exchange available' is shown during game, skip it first by pressing the start button. Then play the game normally until the gal throws her last tile out. Keep pressing the 'DonDen' button for almost 40-50 times and 'Three Tiles Exchange available' will appear again. The other two chances of exchange will come after pressing the button 4-6 times each. Attempt to make your whole tile group to match the opponent's last tile after exchange then a Ron of Yakuman can be achieved. It will be easier to fulfil this trick if the gals last tile is forced to be the one expected.
