Cashable Bonuses
Cashable bonuses often restrict play on certain games. Wagers made on roulette, baccarat, craps, and sic bo usually do not count towards the wagering requirement because these bets give the player the opportunity to simultaneously bet on winning and losing outcomes, greatly reducing variance. For example, betting on both red and black in roulette. Wagers on games with a low house edge, like blackjack and video poker, are also often excluded. Some casinos increase the wagering requirement above the default for low-house-edge games.
On games without raises or doubles, the expected loss while completing a wagering requirement is wagering requirement * house edge. This makes the expected gain of a cashable bonus equal to bonus - wagering requirement * house edge. House edge is defined in terms of initial bet, so the above equation does not apply to games with raises and doubles where the final bet size may be larger than the initial bet. The equation becomes bonus - wagering requirement * average loss per wager. WizardofOdds.com has proposed calling the latter average loss per wager variable "element of risk".[1] For a more precise estimate, one must also consider the benefit from being able to bet the bonus prior to completing the wagering requirement. This effect becomes noticeable when making large bets, such as betting the full balance (deposit and bonus) in a single bet. After considering this benefit and "element of risk", the formula for return becomes bonus - average wagering * element of risk.[2] If games without raises or doubles are played and the bonus is not given until completing wagering, then the formula can be simplified as bonus - wagering requirement * house edge.
