Bonus Math
Understanding the mathematics behind casino bonuses helps you make informed decisions. Consider a typical welcome bonus: deposit €100, receive a 100% bonus up to €200, with a wagering requirement of 40x (deposit + bonus). First, calculate the total wagering required: (€100 deposit + €100 bonus) × 40 = €8,000. Assume the slot you play has an RTP of 96%. The expected loss from wagering €8,000 is €8,000 × (1 – 0.96) = €320. Therefore, the net expected value of this bonus offer is the bonus amount (€100) minus the expected loss (€320) = -€220. This means in the long run, you are likely to lose money. However, if you find a slot with a higher RTP, say 98%, the expected loss drops to €8,000 × 0.02 = €160, and the net expected value becomes €100 – €160 = -€60. Note: if the wagering requirement applies only to the bonus amount (e.g., 40x bonus), then wagering = €100 × 40 = €4,000, and expected loss at 96% RTP = €4,000 × 0.04 = €160, net EV = €100 – €160 = -€60. Always check the terms.

Good to Know
For the best RTP, focus on video slots with published RTPs of 96% or higher. Classic slots often have lower RTPs. Table games like blackjack (with optimal strategy) can offer RTPs over 99%. Avoid keno and some scratch cards as they tend to have lower RTPs. Always check the game info before playing.
