Bonuses are sold as big numbers and hidden in small print. One formula beats all of them: real value = bonus value minus the cost of the turnover you must complete. The deltabet88 casino guide explains the terms; this article drills the calculation.
The four numbers to look for
- Bonus value — the advertised figure.
- Turnover / wagering requirement — how many times the bonus (or bonus + deposit) must be wagered.
- Time limit — the days allowed to complete the turnover; enough for your playing pattern or not.
- Game contribution — slots usually count 100%, live tables often 10% or zero. This figure multiplies the turnover effectively.
A short worked example
A 100-unit bonus with 20x turnover means two thousand units must be wagered before withdrawal. On a 96% RTP game, two thousand wagered is expected to lose 80 units on average — so the bonus's real value is roughly 20 units, not 100. Still positive on paper; nowhere near as exciting as advertised.
When declining is the smarter move
- Turnover exceeds 30x of bonus + deposit.
- The time limit is shorter than your realistic playing pattern.
- Winnings are held until the full turnover is completed — all of it.
- Terms change without clear notice.
A bonus is not the enemy — just a number to read before accepting. And the same principle applies to accounts: the deltabet88 registration guide stresses that a healthy account starts with limits, not bonuses.
