How We Test the Chance of Winning

As described earlier, casinos can modify your chance of winning on popular slots — and OnlyWin has lowered your chances of winning for some games.

They can do this by changing what's known as the return-to-player or RTP. The lower the RTP, your odds of winning are lower — and the casino profits more.

Our testing checks this by checking the same 10 top games at each casino and checking their RTP settings against the best RTP versions of those same titles.

You can check out the full breakdown just below. Swipe to the right to discover how different casinos compare with eachother.

It's critical to know that the casino you're playing at has fast and reliable customer service in case you ever actually need it. However, it can be tough to measure the quality of customer service across 155 online casinos.

OnlyWin - Slots and Other Casino Games

4 out of 5 stars

Variety keeps online play interesting; the same slot again and again won’t. Checking all the game libraries across casinos to find the best is no small task.

We assessed OnlyWin on two fronts: how many games it offers and how many types—sports betting, live dealer, slots, blackjack, and roulette.

Keep going to learn how OnlyWin stacked up in our game library test.

OnlyWin - Website Speed and UX

3.5 out of 5 stars

A slow loading casino site can spoil your whole session. It’s difficult to measure how fast an online casino is compared to the field. We timed how long pages take to load at each casino and ranked the outcomes to flag the slowest.

How Fast is OnlyWin?

With an above-average result at 23rd place, OnlyWin nonetheless ranked about mid-pack for online casino page loads. Average loads of 3.0 seconds won’t hinder play much, even if the top casinos are speedier.

OnlyWin - All Test Results

Compilation of all casino tests and calculations for rankings.

Bonus and Promotions Test.

We evaluated bonuses and promos at every casino, counting both no-deposit deals and first-deposit offers. Since max eligible deposits differ by site, we measured first deposit bonuses using a $100 baseline.

We calculate TBV (Theoretical Bonus Value) and adjust the metrics and playthrough rules based on the bonus we’re reviewing. TBV100 evaluates bonus value with a $100 deposit; TBVMAX does the same using the maximum permitted deposit.

Here’s how OnlyWin performed in our bonus and promo tests.

You won’t get a No Deposit Bonus when joining OnlyWin.

  • First Deposit Bonus Type: Match + Freespins
  • Minimum Deposit Amount: 20
  • Theoretical Bonus Value for a $100 First Deposit: $94.18
  • TBV100 First Deposit Rank: 10th out of 155
