What is the Bau Cua house edge?: About 7.9 percent — higher than other games because 4x payout for 3 matches is rare (about 1/216 odds).
Are there bet limits?: Minimum bet is 5 USDT. This page caps the input at 500 USDT; the REAL ceiling is the bankroll's Kelly fraction, which moves with liquidity — whichever is lower applies.
