Online slots can mess with your head. The “same” title on two sites can feel totally different. Read on to see how I confirm which return version I’m on.
If you want to run RTP checks in one spot, VegasNow Casino AU fits. It has a welcome offer, a pokies-first lobby with 7,000+ games, and AUD plus crypto play. Deposits take Visa/MasterCard, Skrill, Neteller, and Neosurf. There’s a VIP cashback setup, an installable web app, and 24/7 chat/email support.
Why One Slot Can Behave Like Two Different Games
Many providers ship one title with more than one RTP setting (96%, 94%, 92% and so on). The casino picks which one to run. So “this slot used to pay better” is often just “you changed casinos.”
I’m not trying to prove a percentage with a short session. I just want the best evidence I can get fast.
Step One: Find The Return Rate Inside The Game
I open the game menu and search for the line that should exist. I click on the Info, Help, or Rules icon. Alternatively, I check the paytable or the rules PDF (often linked from the help screen).
If I see the number, I screenshot it with the casino name visible. I also jot the date in my notes, so I can compare later.
Note that the casino lobby text can be generic. I’ve seen a lobby claim one value while the loaded game showed nothing. I trust what the game itself shows first.
Step Two: Confirm The Same Build
Before I compare sites, I remove easy mistakes. I once tested “the same slot” and later noticed the provider name was different. That’s on me.
- Same provider and title.
- Keep one bet size for the whole check (I often use €0.20).
- Use plain mode first. Turn off extra toggles (ante, add-ons, bonus buy).
If the info screen shows a build/version line, I note it. If two builds differ, I don’t compare results.

Paytable Checks That Catch Different Versions Fast
When the return number is hidden, the paytable is my next stop. I compare it at the casinos. I look at:
- Top symbol pays
- Scatter payouts
- Wild rules
- Bonus trigger rules
- Max win line (if listed)
If any of these differ, I stop.
My Mini-Test
If the paytable matches and I still can’t confirm the setting, I run a short test to spot real differences. I’ll do it on one site (say, wicked jackpots) and then repeat it on the next casino with the same setup. I write the results in Notes. My method:
- Pick one flat bet (example: €0.20)
- Do 3 blocks of 200 spins
- Track four stats:
- Total in / total out
- Bonus triggers
- Biggest single win
- Dead spins (0 return or almost 0)
Then I repeat the same plan at the other casino.
| Check | Casino A | Casino B |
| 600 Spins Return | % | % |
| Bonus Triggers | # | # |
| Biggest Win | x bet | x bet |
| Dead Spins | # | # |
How I Read The Results
When interpreting the outcomes, I look for big differences. Bonus frequency, for example, matters more than where I ended the session. A much higher dead-spin count can also be a real clue. And one big spike means nothing. Big wins can land on any version.
An example from my notes: same slot, same bet, same 600-spin plan. One casino gave me 2 bonuses and long blank runs. The other gave me 8 bonuses and fewer dead patches. That’s enough for me to treat them as different (even if I can’t name the exact setting).
If both casinos look close on triggers and dead spins, I assume the version is the same, or the gap is too small to spot in a short test.
How I Get A Straight Answer From Support
A good idea is to clarify the RTP with the helpdesk team. When doing so, I keep the message short: “What return setting is enabled for [Slot Name] by [Provider] on your site? Please confirm the exact %.”
If they won’t confirm it or link to matching rules, I move on. I don’t play blind.

Stop Guessing — Make The Slot Prove It
As you can see, my routine is simple: check the RTP in-game, confirm the build, compare paytables, then run a clean mini-test if you need extra confidence. It won’t give you perfect math, but it helps you avoid the wrong version.
