For the challenge, we need to gain enough money (self.dollars >= 130), we should obtain the flag. Observing the PRNG, we can see that the PRNG is a Linear Congruential Generator, with properly randomized parameters. Let’s first discuss how to break the LCG. Denote the multiplier mul as $M$, increment inc as $I$, modulo as $N$. We can easily retrieve $M, I$ after obtaining three numbers from the LCG, denoted by $A, B, C$....
