To Install Game App: If you have not already downloaded the app in the past, download the MahjonggProWin.zip file using the button below. Open MahjonggProWin.zip and extract (“Extract all” button at top) the 2 files (MahjonggProWin.exe and MahJonggProWin.pck) to a new empty folder. The folder name and location don’t matter, just remember them. Then double click the MahjonggProWin.exe app file with the red dragon icon to start the game. Windows Defender may warn that the app might not be safe since it was downloaded from the Internet. You need to dismiss this warning to run the app. Select the “More info” option and then “Run anyway” to run the game. Windows should not warn you again in the future when you run this same file.
You can log out of this website when you are playing the game.
