How We Test the Chance of Winning

As discussed above, casinos can lower your odds on most slots — but Winz.io decided to not lower your odds.

They could cut your chances of winning by tweaking a setting called the “Return to Player” (RTP). The lower the RTP, your odds of winning get worse — and the casino's profit grows.

We verify this by looking at the same 10 popular games at each casino and checking their RTP settings to the maximum RTP possible.

Take a look at the detailed results just below. Swipe to the right to check out how other online casinos did.

Visit Winz.io Slide to compare

By swiping, it becomes obvious that Winz.io ranks among the top casinos that we scored. You've got a couple of other great casinos, even so we would feel confident suggesting you play at Winz.io if you want a great chance of winning.

when you play online slots the return-to-player setting is the key element that can have the biggest impact on your odds of winning real money.

If you’re looking for ways to increase your odds while playing online playing at a casino with high RTP makes a difference. Winz.io is among the best we’ve tested, plus there are other strong options in our list of the best online casinos.

How Much Higher is Your Chance of Winning?

A lot of popular slots are launched with multiple versions with varying RTPs. Here's a good example — the Gates of Olympus slot is set to 96.50% RTP but one that runs at 94.50% RTP.

The 2 game versions have identical gameplay even though they give different returns over time.

Each casino can decide whether to select a higher-RTP version versus a version that pays less.

Some of the online casinos use the higher RTP versions because they know players like to win to motivate them to play more.

On the other hand, many other casinos go with the lower RTP versions because they want you to lose as much as possible.

If you want to be a winner while playing slots be sure you're playing on one of the casinos we've labeled as "High Chance of Winning." The difference between choosing a good or bad casino for playing slots can play a major part on how often and much you win.

Winz.io - Bonus, Promos, and Free Spins

1 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 55th out of 141.

While the value tops the average, it misses the mark set by Art Casino by $100.93. With a $100 deposit, TBV of $2.33 is around $51.07 better than average — solid, but not #1.
