What is the house edge in crash games?

Most provably fair crash games have a house edge between 1% and 3%. This is built directly into the crash point formula as a constant (99 for 1% edge, 97 for 3% edge). The house edge manifests as a percentage of rounds that crash instantly at 1.00x before anyone can cash out. In a 3% edge game, approximately 3 out of every 100 rounds crash at 1.00x. The expected value is negative by exactly the house edge percentage regardless of which multiplier you target.
