How to Compare Casino Bonuses Like a Pro

With hundreds of online casinos competing for your attention, bonus offers are everywhere. "200% match!" "500 free spins!" "£1,000 welcome package!" The numbers look impressive, but the reality is often more nuanced. Not all bonuses are created equal, and the biggest number doesn't always mean the best deal.

This guide teaches you how to compare casino bonuses like a pro — looking beyond the headlines to find offers that genuinely give you the best value.

Step 1: Look Past the Headline Number

The first thing most people notice is the bonus amount — "up to £500" or "up to £1,000." But this number is often misleading for several reasons:

• It's the maximum, requiring the maximum deposit to claim in full
• It doesn't account for wagering requirements that determine whether you can actually withdraw winnings
• It might be spread across multiple deposits over weeks

A £100 bonus with 10x wagering is almost always better than a £500 bonus with 50x wagering. The first requires £1,000 in total bets; the second requires £25,000. Focus on realistic value, not maximum potential.

Step 2: Calculate the Real Wagering Cost

The most important comparison metric is the total wagering requirement. Here's how to calculate it:

Total wagering = (Bonus amount) × (Wagering multiplier)

Or, if the requirement applies to bonus + deposit:

Total wagering = (Bonus + Deposit) × (Wagering multiplier)

Then consider what percentage of that wagering you're statistically expected to lose, based on game RTP. On a slot with 96% RTP, you lose about 4% of total wagering. So £10,000 in wagering costs you roughly £400 in expected losses.

This concept — the "expected cost" of clearing a bonus — is what separates casual bonus users from informed ones. Read our wagering requirements guide for a deeper dive.

Step 3: Compare Game Contributions

If slots contribute 100% and table games contribute 10%, a bonus is effectively worth 10x less for table game players. Before comparing bonuses, check:

• Do your preferred games contribute fully?
• Are any games excluded entirely?
• Are there specific games required (as with free spins)?

Step 4: Check the Time Limit

A 30x wagering requirement with a 30-day expiry is manageable. The same requirement with a 7-day expiry is extremely aggressive — you'd need to wager heavily every single day. Make sure you can realistically clear the requirements within the given timeframe based on your typical playing habits.

Step 5: Evaluate Maximum Bet and Withdrawal Limits

Maximum bet: Most bonuses cap your bet at £5 per spin while wagering is active. This protects the casino but also slows your wagering progress. Check if the limit is reasonable for your playing style.

Maximum withdrawal: Particularly relevant for no deposit bonuses, which often cap withdrawals at £20–£100 regardless of how much you win. Always check this before playing.

Step 6: Consider the Casino Itself

The best bonus in the world isn't worth much at a poor casino. Factor in:

• Licensing: Is the casino licensed by a reputable authority (UKGC, MGA, state regulators)?
• Game selection: Does the casino offer games you enjoy?
• Withdrawal speed: How quickly does the casino process withdrawals?
• Customer support: Is live chat available? Are they responsive?
• Reputation: What do other players say about their experience?

Step 7: Compare Bonus Types

Different bonus types suit different players:

• Cautious beginners: No deposit bonuses or free spins let you try with zero risk
• Regular players: Cashback bonuses provide ongoing value
• High depositors: Deposit match bonuses with low wagering offer the most absolute value
• Competitive players: Tournament bonuses add excitement and the chance for big prizes

Common Traps to Avoid

1. "Sticky" bonuses. Some bonuses can't be withdrawn — only the winnings can. This means the bonus amount is always deducted from your balance when you cash out.
2. Minimum deposit traps. A bonus might require a £20 minimum deposit but the best terms only apply to deposits of £50+.
3. Auto-opt-in bonuses. Some casinos automatically add bonuses to your deposit. If you don't want the wagering restrictions, you may need to opt out before depositing.
4. Country restrictions. A great bonus might not be available in your region. Always check eligibility. Browse bonuses by region: UK, US, Canada.

A Simple Comparison Framework

When comparing two bonuses side by side, use this quick checklist:

1. What's the total wagering in pounds/dollars?
2. Is it bonus-only or bonus + deposit wagering?
3. How many days do I have to clear it?
4. Are my preferred games eligible at 100%?
5. Is the maximum withdrawal reasonable?
6. Is the casino reputable and licensed?

Run through this for each offer, and the better deal will usually be obvious.
