This is a new breed of APK modding on Android. Xmodgames essentially is a launcher that allows you to install mods enabling cheating options onto your games, then launch those games and even allows you to access advanced option in the game itself. Xmodgames even allows for the running of Lua Scripts (Bots) that can automatically perform actions such as raiding, collecting rewards, doing social reward collection ect. Xmod Games is arguably a very good alternative to straight up downloading modded APKs from random websites with added benefits.
However, the downside to using this launcher is that online games are starting to ban people that have xmodgames files on their phone no matter if they used it on that game or not. So do be very careful and please don’t use this on your online games before testing it on a separate device on a dummy account.
