Bonus bets are “credits” or “cash” only redeemable with bookmakers. Bonus bets are not real cash but can be used as if they were real cash to create risk-free opportunities for guaranteed tax-free profit. Bonus bets are provided by bookmakers as an incentive for depositing or as compensation for losing bets. The Sports Maximiser identifies the best opportunities for converting bonuses directly to cash using a number of calculations to determine the conversion percentage. These are then presented to the user from best to worst and for whatever bookmakers/sports/leagues/markets that the user desires.
