Winz.io Casino – Review

Winz.io - Bonus, Promos, and Free Spins

3.5 out of 5 stars

We tested first deposit deals everywhere to figure out which site stretches your deposit the most.

We use a formula called Theoretical Bonus Value (TBV) to calculate the average return players receive on their first deposit after meeting all the wagering requirements from minimum to maximum allowable deposit amounts.

These are the results for Winz.io.

By our numbers, Winz.io’s first deposit bonus totals $2.33. Within our $100 baseline review, it stood at 51st out of 166.

While the value tops the average, it misses the mark set by Blindluck Casino by -$102.33. With a $100 deposit, TBV of $2.33 is around $215.78 better than average — solid, but not #1.

4.5 out of 5 stars

Customer service is a key consideration for online casino players, and it shouldn’t be ignored. Count on a site that won’t leave you waiting when you ask for support. Measuring customer service across 166 casinos is tricky.

We rate customer support across casinos so you know what to expect before you start.

Winz.io - All Test Results

Compilation of all casino tests and calculations for rankings.

Bonus and Promotions Test.

Our tests covered both no-deposit bonuses and initial deposit offers across all online casinos. Because casinos cap bonuses at different amounts, we standardized on a $100 first deposit for testing.

We call our calculation the Theoretical Bonus Value (TBV) and it includes different metrics and playthrough requirements depending on the bonus we're evaluating. TBV100 reflects a $100-deposit scenario, while TBVMAX reflects the max-deposit scenario for that offer.

Here’s our read on Winz.io’s bonus and promotion performance.

Winz.io does not include a No Deposit Bonus in its new-player offers.

You won’t receive a First Deposit Bonus when you make your first deposit at Winz.io.

• Number of Bonus Spins: 25
• Max RTP of Bonus Spins: 96.16 %
