How to use LuckyGameTools for Denuvo startup verification(Video guide)

1
After installed the game, a pop-up message will appear when starting the game indicating that the Denuvo game needs to be activated
2
Exit the running Steam
3
Copy the complete mystery code(The mystery code is a string of characters starting with the letter lgt, valid for 30 minutes;How to get the mystery code, please refer to the contribution method in the following text for details )
4
When the mouse hovers over the corresponding game on the left side of this software, a triangular start button will be displayed. Clicking on it will start Steam (if it doesn't appear, it may be a system clipboard issue, try pasting it in an empty space)
5
Log in to your account (make sure to start Steam from step 4 for it to be valid)
6
Launch the game,After waiting for verification to complete (there will be a pop-up window in English indicating successful verification and automatically exiting Steam)
7
Then everyone can start Steam normally and play the game smoothly(No need to use the mystery code again after the process completes; do not update the system after verification)

Tip：

1.Denuvo is an official game verification mechanism (this software only assists with the startup verification workflow). The general principle is that encrypted game files are bound to the system, so verification is usually only needed again when the system or game files change. If the verification status expires, please complete the flow again with a new mystery code.

2.For games that jump from Steam to a third-party platform, you currently need to log in to a third-party platform account that owns the Steam version of the game before the game can finally launch. After the game launches successfully, use the Toolbox in this software for the supported third-party platform helper flow, for example: Assassin's Creed Shadow on the Ubisoft platform.

How to play that require network authorization verification single player games？

Warn：

Refer to the Denuvo startup verification steps; the difference is that the mystery code starts with lot (each time the game is played, it needs to be started through the code)
