About us
BigBadBonus.com compares online casino offers. Every card shows the terms that decide what a bonus is worth: the wagering, the minimum deposit, the cap on the package and, when you open it, the rest of the small print.
The reason is simple. A big match or a few hundred spins says little on its own; the playthrough, the maximum bet and the expiry decide how much of it you are ever likely to withdraw. So those terms sit on the card right beside the headline, and the guides turn them into the amount you would have to bet before a bonus becomes money you can take out.
What we cover
An international section in euro, and country sections for Canada, Finland, Austria and Ireland. Each section lists only offers its players are allowed, with amounts in their currency exactly as the casino publishes them. We never convert currencies.
On the international pages an offer card switches to your local currency only when the casino publishes every amount on that card in it; otherwise the card stays in euro rather than mixing two currencies on one card. The Canada section is for players aged 19 and over outside Ontario and Alberta, which run their own regulated markets. Visitors from those two provinces can still read every guide and fact sheet, but the offers and their links are not shown to them.
What you will find here
- Bonus lists by type, from welcome packages and free spins to no-deposit, cashback and wager-free offers.
- Casino reviews and fact sheets, with every casino scored out of 10.
- Payment method pages in the country sections, showing which casinos take a method.
- Guides to bonus terms, games and licences, and in the Canada section to sports betting too.
- Calculators for wagering, odds and parlays on the tools page, free and without sign-up.
How we work
We read each casino's published bonus terms, cashier and licence details, and cross-check them against other sources. Each offer shows the date we last read its terms. We do not claim to have played, deposited or cashed out at the casinos we list. How we rate casinos explains the scores.
Every offer is stored once, as a record holding its terms and the day they were read, and the cards, tables and charts across the site are built from that one record. When an offer passes its end date, or a casino is paused, the next build of the site drops it from every list instead of leaving a dead offer on the page.
How the site is paid for
Some casinos pay us a commission when a player joins through our links. That never changes a score or a ranking rule. Details are in the affiliate disclosure.
Who writes it
Everything on the site is written and checked by the BigBadBonus team. There are no named authors and no invented experts behind the byline; the team page sets out who signs the work and how the terms are checked.
