I'm not really sure, I don't really understand what he means. With knowledge of the server seed, it probably only takes a few hundred CPU cycles to figure out the required client seed to win. (let x be a random number in the winning range. Then use a client seed of:  (x -serverseed) % 2^32.  Or if you're lazy and want to brute force a client seed -- there's only 4 billion possibilities, and it's a simple range check, so you can scan the entire range in under a second. But you don't even need to scan the entire range, as there's probably at least 50 possible client seeds (if you're randomly searching) so it's an extremely fast operation.


Or let's forget all that, and let's assume that it takes 6 minutes to find a client seed and the player was betting every 3 seconds ...  that means the player has a ~1.6% of finding the seed in between their normal bet. But if they win, they get like a million times their money. Auto-betting with a 1.6% chance of making a million times my bet .... in a few minutes of betting, you're almost guaranteed to hit the jackpot
