Customer Support
21Bit Casino provides customer support via email and live chat. However, live chat is not available in all countries. Despite this, players report satisfaction with the support team, noting quick response times and helpful assistance.
Every player, choosing an online casino, hopes for fair playing conditions. That's why I checked the RTP in 21bit Casino slots – to find out if it reduces players' chances of winning or plays by the rules. Let's break down the results in detail, provider by provider.
AvatarUX RTP
Let's start with AvatarUX. Here, all the verified slots showed a stable RTP of around 96%. This is a good indicator that meets the stated standards of the provider. You can play AvatarUX slots at this casino without fear - no decreases have been found.
-
Animals Strike – RTP 96%
-
Gods Gone Wild – RTP 96%
-
Imperial Coins – RTP 96%
-
Pixel Paws – RTP 96%
-
Tik Talkers – RTP 96%
-
Tikipop Spooky Temples – RTP 96%
Bgaming RTP
A pleasant surprise from BGaming - here the RTP is even higher than 96%! Some slots go up to 97% or higher, which is always pleasing. This means that the casino does not interfere with the return percentage and players get a fair chance of winning. Such a result inspires confidence.
-
Disco Party – RTP 97.01%
-
Forgotten – RTP 96.89%
-
Golden Pride – RTP 96%
-
Hot Chilli Bells – RTP 97%
-
Lucky Ducky – RTP 97.25%
-
Sakura Riches 60 – RTP 97.16%
ELK RTP
All tested slots turned out to have an RTP of 94%, which is noticeably lower than the usual level. However, this is not a deception of the casino, but a feature of the provider - ELK often releases slots with such an RTP. Therefore, despite the low percentage of return, there are no reductions from 21bit Casino.
-
Catemple – RTP 94%
-
Cygnus 5 – RTP 94%
-
Reindeer Royale – RTP 94%
-
Shadow Shifter – RTP 94%
-
Tinkerbot – RTP 94%
-
Tropicool 4 – RTP 94%
Evoplay RTP
With Evoplay, the situation is more balanced. Basically, the RTP stays within 96%
-
Big Catch – RTP 94%
-
Bull's Club – RTP 96.02%
-
Cursed Castle – RTP 96%
-
Dolce Dreams – RTP 96.03%
-
Mega Merry Gifts – RTP 96.27%
-
Sea Of Wealth – RTP 96.15%
Hacksaw RTP
Here we already see a decrease in RTP. Two slots were below the norm: Fire My Laser and Klowns. Under normal conditions, their RTP is 96.2% and 96.23%, but at 21bit Casino it is reduced to a little over 94%. This is already a reason to think. Although the rest of the slots are not affected, the presence of decreases makes you wary.
-
Fire My Laser – RTP 94.16% (normal 96.2)
-
Get The Cheese – RTP 96.31%
-
Klowns – RTP 94.31% (normal 96.23)
-
Le Viking – RTP 96.32%
-
Marlin Masters – RTP 96.24%
-
Phoenix Duelreels – RTP 96.27%
Mascot RTP
But with Mascot the situation is even worse. Here, almost all tested slots received a decrease in RTP. Instead of the standard 95-96%, their figures fell to 90-92%. This is a strong deterioration in conditions for players, and playing slots from this provider is clearly unprofitable here. When the RTP drops so low, it becomes almost impossible to count on stable wins.
-
Ice Number One – RTP 90.99% (normal 95)
-
Lucky Year 25 – RTP 91.71% (normal 95.1)
-
Metal Frontiers – RTP 92.36% (normal 95)
-
Reel Eldorado – RTP 97.71%
-
Riot Ultimate – RTP 92.46% (normal 96)
-
Yukon Fever – RTP 91.93% (normal 95.6)
Netent RTP
This provider also did not do without reductions. At 21bit Casino, the RTP of Mine Blown, Mummy Megaways, and Ticket To Wild is understated. Instead of the standard 96%, they dropped to 94%, which, of course, is noticeable. The rest of NetEnt slots are honest here, but the very fact of the reductions raises questions.
-
Dazzle Me Christmas – RTP 96.17%
-
Mine Blown – RTP 94.13% (normal 96.17)
-
Mummy Megaways – RTP 94.17% (normal 96.2)
-
Rabid Randy – RTP 96.06%
-
Starburst Galaxy – RTP 96%
-
Ticket To Wild – RTP 94.05% (normal 96.04)
Nolimit City RTP
Finally, one of the most popular providers shows stability. All Nolimit City slots at 21bit Casino have not been changed — the RTP is kept at the stated level. It's nice to see this after a few instances of RTP drops in other providers.
-
Blood & Shadow 2 – RTP 96.09%
-
Brute Force – RTP 96.08%
-
Duck Hunters – RTP 96.05%
-
Munchies – RTP 96%
-
Outsourced – RTP 96.08%
-
Xways Hoarder 2 – RTP 96.14%
Pragmatic Play RTP
Another honest result. Pragmatic Play has maintained its standard RTP rates at this casino – all slots run at 96.5%. This proves that the casino does not interfere with the provider's settings and gives players an equal chance of winning.
-
Ancient Island Megaways – RTP 96.55%
-
Greedy Fortune Pig – RTP 96.50%
-
Irish Crown – RTP 96.52%
-
Mining Rush – RTP 96.56%
-
Tiny Toads – RTP 96.51%
-
Wild Wildebeest Wins – RTP 96.51%
Quickspin RTP
Everything is clean here too. The RTP of the tested slots has not changed, everywhere the figures are above 96%. Players can expect fair gameplay without artificially reducing returns.
-
Book Of Yuletide – RTP 96.27%
-
Candy Glyph – RTP 96.19%
-
Pineapple Crush – RTP 96.01%
-
Reel Nightmare – RTP 96.23%
-
Shields Of Lambda – RTP 96.13%
-
Temple Of Paw – RTP 96.01%
Thunderkick RTP
Some of the slots here come with an RTP of 94%, and some with 96%. But a decrease in RTP was not found on the part of the casino, since the provider itself produces slots with such a percentage of return. These are standard values for Thunderkick, so there are no special complaints.
-
12 Bolts Of Thunder – RTP 96.15%
-
Archie O'loggins And The Enchanted Masks – RTP 94.16%
-
Bones & Bounty! – RTP 96.16%
-
Hot Turkey – RTP 94.13%
-
Split Happens – RTP 94.16%
-
Ways Of Athena – RTP 94.21%
Yggdrasil RTP
A situation similar to Thunderkick. Some slots come with a 94% RTP, but that's the basic settings from Yggdrasil, not the casino's fault. At the same time, there are also high indicators, for example, Tuts Twister with 97.1%. In general, no deviations from the norm were recorded.
-
Fatzs Diner Gigablox – RTP 96%
-
Merlin's Beard – RTP 94%
-
Rainbow Ryan 2 – RTP 94%
-
Trickstar Spins – RTP 94%
-
Tuts Twister – RTP 97.1%
-
Valkyries – RTP 96%
Is it possible to win at 21bit Casino?
After the analysis, it becomes clear that 21bit Casino reduces the RTP in some slots. This is especially true for the providers Mascot, Hacksaw and NetEnt, where a significant decrease in the percentage of return was revealed. In some cases, the decrease reached 5-6%, which is critical for players. However, there is good news. Many providers such as AvatarUX, BGaming, Nolimit City, Pragmatic Play, and Quickspin have not undergone any changes, and here the RTP has remained at the advertised level. What does it mean? Winning at 21bit Casino is real, but not in all slots. If you play proven slots without a reduced RTP, the odds remain fair. However, if you accidentally get into a low slot, it will be difficult to count on winning. Be careful about your game selection and avoid slots with a reduced RTP!
