it truly depends on how the game is set up. if the devs spent tons of money into anticheat and secruity and (server-side purchases) then your chances are slim to none...but such as dmg hacks and slight chance of maby god mode u can still get away with it on some apps
but anyways newer games like asphalt 9 & undead rivals from gameloft...lol good luck getting gem hacks or gold hacks anymore . devs are becoming more wise to the good old (apk mods)
