Calculating Your Bonus
When you claim a 21bit bonus, you need to understand the wagering requirements. Let’s calculate the real value of a typical welcome offer.
Important: All bonus calculations are estimates; always check the specific terms of your offer.
Example offer: 100% deposit bonus up to $500 + 50 free spins. Wagering requirement: 35x (bonus + deposit).
Suppose you deposit $200. You receive a $200 bonus. Your total balance is $400 (deposit $200 + bonus $200). The wagering requirement is 35 × ($200 deposit + $200 bonus) = 35 × $400 = $14,000. You must place bets totaling $14,000 before you can withdraw any winnings from the bonus.
If the game contribution is 100% for slots, 10% for table games, then playing only slots counts fully. So you need to wager $14,000 on slots. Average slot RTP is 96%, meaning expected loss per $1 wagered is $0.04. Over $14,000, your expected loss is $14,000 × 0.04 = $560. Since your bonus + deposit total is $400, you are expected to lose more than your bonus. Always choose low‑wagering bonuses or high RTP games to improve your odds.
Formula: Expected value = (bonus amount) – (wagering requirement × house edge). Here: $200 – ($14,000 × 0.04) = $200 – $560 = –$360. Negative means the casino has the edge.
Tip: Some bonuses have “max bet” limits (e.g., $5 per spin). Exceeding voids the bonus.
