Bonus Math
Let’s calculate the true value of a typical king billy casino bonus. Suppose the welcome bonus offers a 100% match up to NZ$500 with a 35x wagering requirement on the bonus amount alone. You deposit NZ$100 and receive a NZ$100 bonus. Wagering requirement = bonus × 35 = 100 × 35 = NZ$3,500. You must wager NZ$3,500 before you can withdraw any winnings from the bonus.
Now consider the house edge. Slots typically have an RTP of 96%, meaning a 4% house edge. Expected loss from wagering = total wager × house edge = 3,500 × 0.04 = NZ$140. Since your total deposit + bonus is NZ$200, the expected value of the bonus is 200 – 140 – 100 (your deposit) = -NZ$40. However, if you pick high-RTP games (e.g., 98% RTP), expected loss = 3,500 × 0.02 = NZ$70, making expected value = 200 – 70 – 100 = NZ$30. So choose games with the highest RTP to maximize value.
Another example: a reload bonus of 50% up to NZ$200 with 40x wagering. Deposit NZ$400, get NZ$200 bonus. Wagering = 200 × 40 = NZ$8,000. At 96% RTP, expected loss = 8,000 × 0.04 = NZ$320. Expected value = (400+200) – 320 – 400 = -NZ$120. This bonus is negative unless you have very high RTP games. Always calculate before opting in.

Formula: Important: Expected Value = (Deposit + Bonus) – (Wagering Requirement × (1 – RTP)) – Deposit. Simplify to Bonus – (Wagering × House Edge). If the result is positive, the bonus is theoretically profitable.

Pro Tips
To improve your chances, focus on slots with the highest RTP. Games like Blood Suckers (98%), Jackpot 6000 (98.9%), and Mega Joker (99%) offer excellent theoretical returns. Avoid games with low RTP, such as many progressive jackpot slots (often 90–93%) and keno (typically 95% or lower). For table games, European roulette (97.3%) is better than American roulette (94.74%). Always check the game info for RTP before playing.
