Low results are common in Crash because of how the multiplier is priced, not because of a hidden setting. With a 1% edge, the chance that a round reaches any multiplier is roughly 99% divided by that multiplier. That means about 49.5% of rounds reach 2x, 9.9% reach 10x and only 0.99% reach 100x, so half the rounds stop before 2x by design.
Crash at Stake proves each result with a chain of hashes generated before the first round and salted with a value fixed in advance. Every round’s hash is revealed when it ends, and running it through SHA-256 gives the hash of the round before, so nobody could have swapped a result. The other Originals use your own seeds instead: a server seed shown to you only as a hash, a client seed you can change at any time and a nonce that counts your bets. Because you set the client seed yourself, the casino cannot pick a result for you in advance, and the modal also counts how many bets you have placed with the current pair.
