Even assuming that it is possible to hack an app downloaded to a smartphone, reverse-engineer, inject your code (to do what?) the architecture of the service is arranged in such a way that it will not bring any benefit in a dubious event of trying to cheat the game, the system to get the winnings. The creators have thought through the protection systems so that all your attempts will be meaningless. In some cases, such attempts can be evaluated from a legal point of view with the further decision on the actions of individuals or groups of persons up to criminal proceedings.
Do not try to find loopholes to circumvent, hack the game and so on. Do not be fooled by advertising on the sale of information or supposedly hacked applications to bypass the game’s protection against hacking – you will lose money.
Just play and enjoy a great game!
