From the Microsoft Store: Click the button below to go to the store listing (Latest version is not currently in Microsoft Store. Please download from this website).
To download from this website:
If you have not already downloaded the app in the past, download the JLMahJonggWin.zip file using the button below. Your browser may want to scan the .zip file to verify it does not contain a virus. Open JLMahJonggWin.zip and extract (“Extract all” button at top) the file JLMahJonggWin.exe to a new empty folder. The folder name and location don’t matter, just remember them. Then double click the JLMahJonggWin.exe app file with the red dragon icon to start the game.
If the game seems to hang at the red dragon screen, the system/antivirus may be asking for permission to use the microphone in a window behind the app main screen. The app can use the microphone to record custom voices for calling the tiles. To bring up the window that is holding up the app, press the Alt and tab keys until the popup window shows up. Then give permission to use the microphone.
If you are playing over a network, a potential problem is a security app deciding to switch the network mode to public (thinks the device is in a public place with public access) instead of private, which stops any communication with external devices. You will need to switch the network mode back to private to play over the network.
Linux: A zipped Linux JLMahJongg executable download link is below. Extract the JLMahJongg folder from the .zip file. In the JLMahJongg folder, right click on the JLMahJongg.x86_64 file and select properties. Select the permissions tab and check the allow executable checkbox. Double click on the JLMahJongg.x86_64 file to run it.
