Sounds even more secure, but how does it work?

The main idea of the process is highly similar to the verification steps. The only difference is the type of hashed RNG (Random Number Generator). “Mersenne Twister Pseudorandom Number Generator” is used for cutting and reshuffling of the decks. As the seed number is only available for the player, there is not a single possibility for the casino operators to manipulate the shuffling process.
