How Does the Sic Bo House Edge Work? Casinos use the sic bo house edge to help them make money. But how does this process work? In sic bo, like many pg slot games, the house edge is so subtle that most players do not notice it. That is because it comes from offering slightly worse payouts than the true odds would imply. the most common way casinos manufacture a house edge is by offering lower payouts. True odds is a term that means the odds are implied by the action at hand. For instance, your odds of rolling a triple are 35-1. However, the casino might only pay you 30-1 for landing a triple. The further away the payout is from the true odds, the higher the house edge.
