Wagering Requirements Explained: the Bonus Maths Worked Out
A casino bonus is money with a turnover condition attached, and the condition decides what it is worth. This page shows how to work that out for any offer, using the figures quoted for SmartPari as the running example. Every number that is an assumption rather than a published term is labelled as one.
SmartPari offer status: the welcome offer quoted on third-party sites is 100% up to €500 plus 200 free spins. The operator's own promotions page and bonus terms are behind a password prompt (HTTP 401) and could not be read on 21 August or 4 October 2026, so the wagering terms below are unknown, not missing by oversight.
Last checked: 4 October 2026.

Earlier versions of this site repeated the same headline figure, so two pages agreeing is not two sources. Until the operator's terms are public, every line below the headline is an unknown, and the arithmetic in the rest of this page is the way to judge the offer once they are.
Restricted countries: SmartPari's list of excluded countries is in the same unreadable terms. If you live in a country the operator excludes, a bonus can be cancelled and the account closed. Check that clause before depositing.
Step 1: Turnover = Multiplier × Base
The wagering requirement is a multiplier, and it is applied to a base: either the bonus alone, or the deposit plus the bonus. The same "35x" can mean amounts that differ by a factor of two.
Example assumptions: €500 deposit, 100% match, so €500 bonus.
| Multiplier | Base = bonus (€500) | Base = deposit + bonus (€1,000) |
|---|---|---|
| 20x | €10,000 | €20,000 |
| 30x | €15,000 | €30,000 |
| 35x | €17,500 | €35,000 |
| 40x | €20,000 | €40,000 |
Step 2: Expected Cost = Turnover × House Edge
Every euro wagered costs, on average, the game's house edge. A slot with 96% RTP has a 4% edge, so €17,500 of turnover costs about €700 on average. Subtract that from the bonus and you have a rough expected value:
Expected value ≈ bonus − (turnover × house edge)
Example assumptions: €500 bonus, slots at 96% RTP (4% edge), weighted 100%.
| Requirement | Turnover | Expected cost | Expected value of the bonus |
|---|---|---|---|
| 20x bonus | €10,000 | €400 | +€100 |
| 25x bonus | €12,500 | €500 | €0 |
| 35x bonus | €17,500 | €700 | −€200 |
| 35x deposit + bonus | €35,000 | €1,400 | −€900 |
Two limits of this simple model, stated so it is not over-read. It slightly overstates the cost, because a player who loses the balance stops wagering early. And it ignores a maximum cashout cap, which can only lower the value. The direction of the answer is reliable even where the exact euro figure is not.
The Break-Even Multiplier
Set expected value to zero and the formula gives a useful shortcut: a bonus breaks even when the multiplier on the bonus equals 1 ÷ house edge.
- At a 4% edge (96% RTP): 1 ÷ 0.04 = 25x on the bonus.
- At a 3% edge (97% RTP): 1 ÷ 0.03 ≈ 33x.
- If the base is deposit plus bonus on a 100% match, halve those figures: about 12.5x at a 4% edge.
Anything above break-even means the bonus is, on average, a cost — which can still be acceptable if you value the extra playing time, as long as you know that is what you are buying.
Step 3: Game Weighting Changes the Edge You Pay
Games often count only partly towards wagering. That multiplies the real cost of each counted euro.
Example assumptions: blackjack with basic strategy, 0.5% edge, counting 10% towards wagering.
To clear €1 of wagering you must stake €10, which costs 10 × 0.5% = 5 cents. The effective edge is therefore 5% per counted euro — worse than a 96% RTP slot counting 100%. A low-edge game with low weighting is not a shortcut, and live dealer games are frequently weighted at 0%, which means they do not count at all.
Step 4: The Maximum Bet and the Time Limit
A maximum bet rule (commonly around €5 per spin while a bonus is active) and a time limit decide whether the turnover is achievable.
Example assumptions: €17,500 turnover, €2 spins, about 500 spins an hour.
That is 8,750 spins, or roughly 17–18 hours of play. With a seven-day limit it is possible; with 48 hours it is a full-time job. Breaking the maximum bet rule, even once, usually voids the bonus and the winnings from it, and it is the most common reason bonus disputes end badly.
Valuing Free Spins
Free spins are worth number of spins × spin value × RTP, before any wagering on the winnings.
Example assumptions: 200 spins at €0.10 on a 96% RTP slot; winnings credited as bonus funds with 35x wagering.
- Expected winnings: 200 × €0.10 × 0.96 = €19.20.
- Wagering on those winnings: 35 × €19.20 = €672 of turnover.
- Expected cost of that turnover: €672 × 4% ≈ €26.90.
On these assumptions the spins are worth slightly less than nothing on average. If the winnings are paid as cash, the same spins are worth €19.20. That single line in the terms — cash or bonus funds — matters more than the number of spins. For SmartPari's 200 spins, neither the spin value nor the treatment of winnings is published.
A Checklist Before Accepting Any Bonus
- Multiplier and base: bonus only, or deposit plus bonus?
- Is the multiplier below 1 ÷ house edge of the games you will play?
- Weighting: does your preferred game count, and at what percentage?
- Maximum bet while the bonus is active, and how the casino enforces it.
- Time limit, converted into hours of play at your normal stake.
- Maximum cashout from bonus winnings, if any.
- Free spins: game, spin value, cash or bonus funds.
- Whether you can decline the bonus and play with your deposit alone.
An offer that does not answer these questions in writing cannot be valued. That is where the SmartPari offer stands on 4 October 2026.
Questions About Casino Bonuses
What does the SmartPari welcome bonus require?
Nobody outside the operator can say at the moment. Third-party sites quote 100% up to €500 plus 200 free spins, but the wagering multiplier, its base, the maximum bet and the time limit are not published anywhere we could reach, and the operator's site has been behind a password prompt since at least 21 August 2026.
How do I calculate a wagering requirement?
Multiply the multiplier by its base. A €500 bonus at 35x on the bonus means €17,500 of bets; at 35x on deposit plus bonus it means €35,000. Multiply the turnover by the house edge of the game you play to get the expected cost, and compare that with the bonus.
Is a bigger bonus better?
Not by itself. A €500 bonus at 40x on deposit plus bonus requires €40,000 of turnover; a €100 bonus at 20x on the bonus alone requires €2,000. At a 4% edge the first costs about €1,600 to clear for €500, and the second about €80 for €100.
Why do table games count less towards wagering?
Because their house edge is lower. Weighting restores the operator's margin: blackjack at a 0.5% edge counting 10% costs 5% per counted euro, more than a typical slot. The weighting table tells you more about a bonus than the headline.
