1) Install the original app, open the game and let the addons install!
2) Log in to Facebook or Google.
3) Complete the initial tutorial.
4) Close the game.
5) "Rename" and change the file name "com.neowizgames.game.bdpuzzle" to "com.neowizgames.game.3bdpuzzle" in the file explorer "android>>OBB folder.
6) File explorer, repeat step 5 in "android>>data" folder.
7) Uninstall the game from the phone.
8) Install the mod.apk you downloaded from the site.
9) Open the game. (It will probably error out and close the game!)
10) Delete the "com.neowizgames.game.bdpuzzle" files installed by the game and undo the operations in options 5 and 6. (delete the "3"s you added!)
11) Open the game again and connect to the social network you started with and continue.
Note: Instant win may not work on every device. But the second option is enough to complete the battles.
In my case, when "Instant win" is enabled, no tiles can be clicked and I have to exit the battle.
