What 18 Licensed Operators Actually Charge You to Clear Their Welcome Bonus
Every licensed operator must, under specific regulatory provisions, disclose the wagering requirement, game contribution, and maximum bet applicable to their welcome offer. The marketing banner says "100% match." The T&Cs carry the rest of the story. This tool runs your chosen scenario against the current published terms of 18 operators so the comparison is on the record instead of in the banner copy.

The Math of Your Scenario
The four numbers every welcome bonus reduces to in expectation.
Your Scenario vs 18 Currently-Licensed Operators
Each row is pulled from the operator's current published T&Cs page. The "Your scenario on this operator's offer" column applies your selected game type and deposit to that operator's actual wagering structure, not a generic average.
| Operator | License | Welcome offer | WR / Base | Max bet | Your EV | Verdict |

Operator T&C source references
Each operator row links to the specific T&Cs page that published these terms. Verification pulled Q1 2026. Material changes since then will be flagged in an update log. When an operator shows different terms in different jurisdictions, the dataset defaults to the published version for the licensed market this site covers.
Why the Math Is Different from What the Banner Shows
When an operator advertises a 100% match up to €100 with 35x wagering, the plain-language reading is "put in €100, get €100 bonus, play through €3,500, withdraw." That reading is arithmetically correct. It is also the version the marketing banner is designed to leave you with.
The piece that never makes the banner is the expected cost of cycling €3,500 through the games. Every game has a house edge — the percentage of every bet that statistically ends up with the operator over a large sample. High-RTP slots cluster around 3-4%. Blackjack played to basic strategy sits at 0.5%. European roulette is 2.7%. American roulette is 5.26%. When you cycle €3,500 through a 4% house edge game, the expectation is €140 in losses — not "that might happen", that statistically will happen over enough bets.
At 35x on €100 with 96% RTP slots:
You started with a €100 bonus. You statistically lose €140 clearing it. The bonus is worth minus €40 in expectation. That is the piece the bonus disclosure rules require operators to make available, but allow to be placed in T&Cs rather than the banner. Legally compliant. Mathematically hidden.
The calculator above is not an opinion. It applies the same formula every licensed operator is already running internally to price their promotional budget. We are running it in the other direction — from the player's side — using the operator's own published terms.
Game Contribution — Why Blackjack Is a Trap Under Bonus
Operators publish one wagering requirement number (e.g. "35x") and a separate rule almost nobody reads: game contribution percentages. Slots contribute 100% toward clearing. Live dealer blackjack typically contributes 10%. European roulette typically contributes 20% or is excluded entirely. Baccarat at 10%. Craps often excluded.
The math of why this matters is brutal. If blackjack (0.5% house edge) counts at 10% contribution, the effective wagering requirement becomes 350x instead of 35x. At that multiplier:
The "low house edge game" becomes worse than high-RTP slots once contribution rates are factored in. This is deliberate operator design — the contribution rate is set such that no legal path through the bonus produces positive expected value for the player at the standard terms. The calculator accounts for contribution automatically.
The Max Bet Rule — Why It Looks Like a Bug but Is a Variance Control
While a bonus is active, most operators cap your bet size at €5 or €10. This cap does not change your expected loss — the expectation is linear in total wagering, not per-bet. It changes your variance. At €5 max bet, cycling €3,500 through the games takes 700 individual bets. At €10 max bet it is 350 bets. Fewer bets means a wider distribution around the expectation.
Higher variance is the only reason any individual player ends up ahead on a negative-EV bonus. The operator's risk-management desk wants to narrow your variance because narrower variance means fewer outlier winners and more players ending closer to the expectation. The max bet rule is a variance compression tool, not a fraud prevention tool, whatever the terms page says about it.
When Is a Welcome Bonus Actually Worth Taking?
Run your specific operator's terms through the calculator above. The industry rules of thumb that emerge from the dataset:
- Wagering below 25x on bonus only with high-RTP slots is usually net positive in expectation. This is rare in the current market — most of the 18 operators audited above charge 35x or higher.
- 35x on bonus only sits at roughly break-even for high-RTP slots. Your edge is variance, not expectation. Make peace with that before taking the offer.
- 50x+ wagering or deposit + bonus base is designed to produce a clear negative EV for the player. Skip unless the match percentage is unusually generous (200%+).
- Low-RTP slots (below 94%) flip even lenient bonuses into negative territory. The operator knows which slot RTPs you are playing on. Pick your game before you pick your bonus.
Methodology and Data Freshness
Operator terms are pulled from each operator's current public T&Cs page — not from third-party affiliate summaries, which sometimes lag the published terms by weeks. The dataset reflects Q1 2026 pulls. When an operator changes their welcome offer materially, we update within 30 days and note the change in the update log. Game house edge data is sourced from published audit reports by eCOGRA, iTech Labs, and Gaming Laboratories International, cross-checked against operator-declared RTP ranges in their compliance filings.
The calculator computes expected value over an infinite sample — the math assumes you play enough bets for variance to average out. Individual outcomes on any specific bonus will deviate from this expectation. The purpose of the tool is to make the long-run expectation visible, not to predict your personal result.
This tool does not use affiliate trackers on any operator link in the dataset. The links point directly to the operator's public T&Cs page so the disclosure is verifiable without commercial intermediation.
