Free Spins Comparison Tool - Spin Wizard - No Deposit Casino Offers

Choosing the best free spins offer isn’t always as simple as picking the biggest number.

Two casinos might both offer 100 free spins, but once you factor in wagering requirements, win caps and qualifying deposits, the real value can be very different.

Our Bonus Comparison Tool helps you see the true expected value (EV) of each offer we list on SpinWizard so you can decide which offer to claim based on real value as the player.

What Is the Free Spins Comparison Tool?

The Free Spins Comparison Tool is designed to bring clarity to casino bonus offers that often look similar on the surface but differ significantly in real value.

A headline like “100 Free Spins” tells you very little on its own. The true worth of any free spins bonus depends on how the spin value, wagering requirements, win caps and qualifying terms interact. When those factors combine, two identical-looking offers can produce very different outcomes.

This tool standardises those variables and evaluates each bonus using the same logic. Instead of relying on marketing claims, you can compare free spins side by side using consistent value calculations based on expected return.

BInstead of manually calculating:

Free spin value
Wagering losses
Win caps
Qualifying costs
Overall bonus expected value

The tool does the maths for you instantly.

What You Can Compare

You can compare virtually any type of free spins offer, including:

No deposit free spins vs deposit-based spins
High-value spins with strict wagering vs lower-value spins with softer terms
Capped vs uncapped bonuses

The tool puts every offer into the same format, so you can compare them fairly based on real value instead of promotional wording.

What the Free Spin Tool Calculates

Our comparison engine breaks each offer down into real monetary value using consistent logic.

For every offer, it calculates:

Free Spins Face Value

Number of spins × spin value.

Expected Return of Free Spins

The return you can expect from using the free spins based on the spin value and RTP (Return to Player) of the slot they’re used on.

Wagering Impact

How much expected value is lost when wagering is applied to winnings.

Qualifying Cost

Expected loss from any deposit or qualifying wager required to unlock the spins.

Total Expected Value (EV)

The realistic estimated value of the offer after qualifying and wagering is taken into account.

The highest EV offer represents the mathematically strongest bonus, not just the biggest headline number.

Understanding the Key Bonus Terms

Before comparing free spins bonuses, it helps to understand what each term really means.

🎰 Free Spins

This is simply the number of spins awarded.

Casinos often promote large free spin offers, but the number alone does not determine value.

100 spins at £0.10 are very different from 100 spins at £0.50.

💰 Spin Value

Each spin has a fixed stake set by the casino (e.g., £0.10, £0.20, £0.50).

Total Face Value = Number of Spins × Spin Value

🚫 Win Cap

Some bonuses limit how much you can withdraw from free spins winnings.

For example:

Max win £50
Max win £100

Even if you win £300, a £50 cap means you can only keep £50.

Uncapped bonuses generally provide stronger long-term value.

🔁 Wagering Requirements

Wagering requirements determine how many times you must bet your winnings before withdrawing.

Common examples:

1x wagering
5x wagering
10x wagering

Higher wagering reduces the realistic value of a bonus because your balance must survive extended play before becoming withdrawable.

All UK-licenced casinos are not allowed to set the wagering requirements of bonuses to more than 10x. Every casino offer you’ll find on SpinWizard is from a fully UKGC licenced casino.

💳 Qualifying Wager or Deposit

Some offers require:

A minimum deposit
A qualifying bet

The tool factors in the expected loss from this requirement when calculating total EV.

Why Expected Value (EV) Matters

We are not trying to predict whether you’ll get lucky.

Instead, we measure which offer gives you:

More value
Fewer restrictions
A better mathematical chance of withdrawing winnings

Expected Value provides a consistent framework for comparing offers objectively.

When Should You Use This Free Spins Tool?

You should use the comparison tool when:

Two casinos are offering similar spin amounts
You’re unsure whether lower wagering beats higher face value
An offer includes a win cap
A deposit is required to unlock spins

It’s particularly useful when multiple bonuses look attractive on the surface but differ heavily in terms.

Tips for Comparing Free Spins Bonuses

Always Check the Win Cap

A low cap can severely limit otherwise strong bonuses.

Lower Wagering Is Often Better

A smaller bonus with 2x wagering may outperform a larger bonus with 10x wagering.

RTP and Volatility Matter

Using high RTP slots improves expected return.

Lower volatility games typically help balances survive wagering requirements.
