A “100 % up to 1 BTC” headline says nothing about what the offer is worth. The conditions do. This guide explains the terms that matter, the clauses we flag, and shows the conditions of every public offer we recorded. Offers are never part of the Smarter Score.
Wagering requirements
“40× the bonus” means you must place bets totalling forty times the bonus amount before you can withdraw bonus-related winnings. Check what the multiplier applies to (bonus only, or deposit + bonus), which games count (slots often 100 %, table games far less or nothing) and the time limit. A 35× requirement on deposit + bonus can be harder than 40× on the bonus alone.
Time limits and maximum bets
Most offers expire in 7–30 days; some in 24 hours. While a bonus is active, many terms cap the stake per bet or spin – exceeding it can void the bonus and winnings. Some terms also define “irregular play” (for example single bets of a large share of the balance) and treat it the same way.
Clauses that change the value of any offer
From the full-text review of the binding terms of the 15 casinos we profile, these clauses appear most often:
- only the English terms are binding – found in 13 of 15 profiled casinos (caution)
- dormant-account fee – found in 10 of 15 profiled casinos (caution)
- withdrawals go back to the deposit method – found in 8 of 15 profiled casinos (caution)
- terms can change without notice – found in 6 of 15 profiled casinos (serious)
- “bonus abuse” defined so broadly it can cover normal play – found in 6 of 15 profiled casinos (serious)
- inactive accounts closed in under 12 months – found in 1 of 15 profiled casinos (caution)
“Serious” flags lower the Terms & Fairness category of the Smarter Score; “caution” flags are documented and shown on the profile. See how we review terms. Every flagged clause of every profiled casino – clause reference, wording as recorded, document and date – is published as a reusable dataset with CSV/JSON download: casino terms and conditions red flags (CC BY 4.0). One caution flag that has nothing to do with bonuses but quietly eats balances is the dormant-account fee – see casino dormant account fees explained.

Some casinos offer rakeback instead of, or next to, a deposit bonus – a share of your wagers paid back. How that works, with worked examples, is in our guide to rakeback explained.
Is a bonus worth taking?
- Multiply: bonus × wagering = the turnover you must generate. Compare it with what you would normally stake in the time limit.
- Check the maximum bet and the eligible games – restrictions on your favourite game make the bonus nearly unusable.
- Read the withdrawal rule: some terms cancel pending withdrawals while a bonus is active.
- If in doubt, decline the bonus. Most casinos let you deposit without it.
A different kind of fairness question concerns game results rather than bonus clauses; how a player can recompute certain results is covered in provably fair, step by step.
A bonus is not money in your pocket
Bonuses are designed to increase play, not to pay out. Treat them as entertainment with conditions, set a limit first, and never chase a wagering requirement with money you need. Responsible gambling. 18+ · T&Cs of the casino apply.
