Owner Functions

FUNCTION INITIALIZED: This function allows you to “pause the contract” since all functions depend on its value, which can be positive or false. The developers have told us that being a WebGL game made with Unity, there is a possibility that the game will be hacked or any type of bug will be found in the game and they can stop any action in the contract in time for the good of the investors. Even if the function is changed to false, no one can continue to perform actions on the contract, not even the owner. Therefore better for the useful life of the project.

The contract does not have any visible or hidden functions that allow you to take money out of the contract


There are no back doors in this contract that anyone (including the owner) can use to their advantage.

Code Complexity

Well developed and structured contract with a lot of code and many well used random number functions such as lucky roulette or having been stolen.

The ‘randomSecurity’ and ‘roulette’ functions emit an event that will be visible in the contract transaction when these functions are called in the Logs tab on
