All Casinos Tested - 4 RTP Reviews, 56 Slots Checked

Why We Test Casino RTP - and What We Actually Found

Most casino review sites pull RTP figures from provider press releases or aggregator databases. We do not. We open each slot in a real money session and record the figure shown in the in-game paytable. That is the only number that tells you what house edge you are actually playing against at that casino, right now.

Here is the thing: providers like Pragmatic Play, BGaming, and Hacksaw Gaming publish multiple RTP variants for most of their slots. A casino licenses the one they want to run. A game marketed at 96% might run at 92% at a specific operator - and you would never know unless you checked the paytable yourself. We check it for you.

So far we have tested 4 casinos and checked 56 slots in total. Wild Tokyo showed a figure on all 15 and GreatSlots on all 14. Pistolo hid 4 of 15, and Wintino hid 3 of 12. On readable slots the averages run 94.97% at GreatSlots, 94.93% at Wintino, 94.87% at Wild Tokyo and 94.05% at Pistolo. The spread between best and worst is worth roughly €88 per €10,000 wagered. Not huge, but it adds up if you play regularly.

Worth noting: a lower-than-published RTP is not necessarily the casino cheating. They are legally running a licensed variant. But you deserve to know which variant. That is what this page is for.

What Our RTP Testing Found - the Short Version

GreatSlots, added in September 2026, now holds the best average in the database: 94.97% across 14 slots, with nothing hidden. Three ran at the full provider maximum, and Coin Flynn Deluxe at 97.00% is the second-best reading we have recorded anywhere. The trade-offs sit elsewhere: real play is locked until you deposit, 11 of 14 slots run reduced variants, and the lobby tiles advertise the maximum while the game serves less.

Wintino sits just behind at 94.93% across the 9 slots that showed a figure. Three ran at the full provider maximum, and Merge Up at 97.25% is the single best reading we have recorded anywhere. The catch is everything around the numbers - no licence, no named operator, 3 hidden RTPs, and a Canadian lobby that quietly drops Pragmatic Play and Hacksaw Gaming. Best settings, worst disclosure.

Wild Tokyo remains the only casino that showed us the paytable figure on all 15 slots - zero hidden RTPs. The average came to 94.87%. Eight of those 15 slots ran below the provider's published maximum - the biggest drop was Merge Up, where BGaming publishes 97.25% and Wild Tokyo runs it at 94.25%. The same slot Wintino runs at full. If you want a strong average AND a licence you can point to, Wild Tokyo is still the pick of the four.

Pistolo is a more mixed picture. The wagering terms are actually better - x35 vs Wild Tokyo's x50, which matters if you take bonuses. The crypto welcome bonus is also genuinely good. But 4 of the 15 slots we tested showed no RTP at all in-game, despite both Amusnet and Novomatic publishing those figures publicly. That is a choice the casino is making. And 3 of the Hacksaw Gaming slots ran nearly 4pp below Hacksaw's maximum variant - that is the steepest cluster we have found at any casino so far.

We will keep adding casinos as we test them. Each one gets every tracked slot its lobby carries, checked on a real logged-in account. No previews, no press access. Read the full methodology →
