In conclusion the house edge in roobet is between 5% and 6%. Closer 5% if you are targeting low multipliers and closer to 6% if you are targeting high multipliers. It's not clear if this is intentional or an artifact of the bustabit v1 code that was copied to generate the game outcomes. Incidentally bustabit currently offers a flat 1% house edge, making it a strictly more economically better place to gamble. And the new moneypot.com offers crash in a very bustabit v1 style odds, with a house edge starting at only 0.1% (but based on a much more complex formula involving the casinos bankroll).
