Well , to be honest , it's not very difficult to mod genius games , but the main reason that it updates security because , it gets the news that it's games are being modded :/
So , in order to protect their games , they ramp up security and made their games server sided . This had the following effect :
Games cannot be hacked with cheat engines like lucky patcher , the currencies like tickets , rubies or points cannot be made unlimited like 99999999 , and in-app purchases are nearly impossible to hack
So if a modder mods the game this time , make sure it remains a secret :)
