The ‘House Edge’ refers the inherent advantage that the ‘House’ has over the player. The ‘House Edge’ is determined by the difference between the True Odds and the Actual Odds that the casino pays out. The RTP is the ‘Return to Player’. It is the percentage of every dollar wagered that is ‘theoretically’ returned to the player over the long-term. The higher the RTP, the lower the House Edge.
