Starting with the BGaming provider. I have carefully examined the RTP figures for this developer's slots on the Prime Slots platform. I can confidently say that the casino does not reduce RTP for this provider. All the checked slots show standard RTP figures characteristic of BGaming games.

• Aloha King Elvis – RTP 94.98%

• Aztec Magic Megaways – RTP 96.11%

• Bonanza Billion – RTP 95.97%

• Dig Dig Digger – RTP 94.82%

• Dragon's Gold 100 – RTP 96.07%

• Elvis Frog In Vegas – RTP 95.30%

Moving on to Blueprint slots, the situation changes dramatically. I was unpleasantly surprised to find that Prime Slots significantly reduced RTP in several games from this provider.

• 5 Pots O' Riches – RTP 95.44%

• 6 In The Chamber – RTP 94.50% (normal 96.05)

• Anubis Rising – RTP 93% (normal 95.8)

• Big Hits Blazinator – RTP 96.08%

• Eye Of Horus The Golden Tablet – RTP 93.03% (normal 96)

• Fishin' Frenzy Big Catch – RTP 95.32%

Although most of the checked games have RTPs below 96%, this is not due to Prime Slots reducing them. These figures are the maximum possible for Elk Studios's slots.

• Ashoka Eternal – RTP 94%

• Avalon Gold – RTP 94%

• Birthday – RTP 96.3%

• Cygnus 3 – RTP 94%

• Katmandu X – RTP 95%

• Pirots – RTP 94%

In almost all checked games from this provider, Prime Slots has significantly reduced RTP.

• 10000 Wishes – RTP 92.10% (normal 96.27)

• 11 Champions – RTP 95.93% (normal 95.93)

• 25000 Talons – RTP 92.09% (normal 96.38)

• All About Christmas – RTP 96.15%

• Book Of Mrs Claus – RTP 92.49% (normal 96.5)

• Fionas Christmas Fortune – RTP 92% (normal 96)

In examining slots from Iron Dog, I found that Prime Slots reduced RTP in half of the checked games. These are significant reductions that cannot be ignored. On the other hand, games like "Arctic Fruits" and "Christmas Megaways" have kept RTP at the standard level.

• Arctic Fruits – RTP 94.6%

• Arriba Heat – RTP 91.07% (normal 94.07)

• Aztec Wilds – RTP 96%

• Christmas Megaways – RTP 96.20%

• Megaways Jack Frost – RTP 94.45% (normal 96.14)

• Santa's Big Bash Megaways – RTP 94.07% (normal 96.04)

Analyzing slots from Kalamba, I was shocked by the extent of RTP reduction in some games. In "Age Of The Dragons Mini Max", the figure dropped from 96% to 91.38%, and in "Big Bounty Bill" – from 96.2% to 91.24%. This is a massive reduction that almost eliminates players' chances of winning. However, there are games with normal RTP, such as "Bangkok Dreams" with an impressive 97.69%. This contrast raises even more questions about the casino's policy.

• Age Of The Dragons Mini Max – RTP 91.38% (normal 96)

• Bangkok Dreams – RTP 97.69%

• Big Bounty Bill – RTP 91.24% (normal 96.2)

• Diamond Bounty Xmas Hold And Win – RTP 91.46% (normal 96.5)

• Griffin's Quest Xmas – RTP 96.50%

• Joker Times Xmass – RTP 96.19%

Checking Netent slots revealed an unflattering picture. Prime Slots has reduced RTP in most of the checked games from this popular provider.

• 101 Candies – RTP 94.07% (normal 96.08)

• Aloha Cluster Pays – RTP 92.02% (normal 96.42)

• Bee Hive Bonanza – RTP 96.09%

• Gem Crush – RTP 93.11% (normal 96.13)

• Secrets Of Christmas – RTP 96.72%

• Starburst – RTP 92.05% (normal 96.1)

The situation with Nolimit City slots at Prime Slots is also very concerning. In all the games I checked from this provider, the casino significantly reduced RTP.

• Barbarian Fury – RTP 94.19% (normal 96.32)

• Beheaded – RTP 92.04% (normal 96.2)

• Benji Killed In Vegas – RTP 92.09% (normal 96.04)

• Book Of Shadows – RTP 94.09% (normal 96.01)

• Coins Of Fortune – RTP 94.13% (normal 96.48)

Moving on to PG Soft slots, I was relieved to find that Prime Slots does not reduce RTP here. All the checked games show high return figures exceeding 96%.

• Bakery Bonanza – RTP 96.74%

• Battleground Royale – RTP 96.75%

• Butterfly Blossom – RTP 96.74%

• Cocktail Nights – RTP 96.75%

• Lucky Neko – RTP 96.73%

• Mahjong Ways – RTP 96.92%

In examining Pragmatic Play slots, I found that Prime Slots reduced RTP in almost all popular games from this provider. Only a few slots, such as "Wolf Gold", have maintained the standard RTP level.

• Big Bass Christmas Bash – RTP 94.60% (normal 96.5)

• Big Bass Christmas Bonanza – RTP 94.62% (normal 96.51)

• Sweet Bonanza – RTP 95.5% (normal 96.48)

• Wolf Gold – RTP 96%

Analyzing Push Gaming slots, I found that Prime Slots reduced RTP in most of the checked games from this provider. For example, in "Big Bite", the RTP dropped from 96.13% to 94.28%, and in "Bison Battle" – from 96.34% to 94.18%. This is a significant reduction that cannot be ignored. However, there are exceptions: slots like "10 Swords" and "Fat Santa" have maintained their original high RTP.

• 10 Swords – RTP 96.46%

• Big Bite – RTP 94.28% (normal 96.13)

• Bison Battle – RTP 94.18% (normal 96.34)

• Dj Fox – RTP 94.31% (normal 96.39)

• Fat Santa – RTP 96.45%

In checking Quickspin slots, I was pleasantly surprised. In most of this provider's games, Prime Slots does not reduce RTP. Moreover, some slots show very high return figures. However, there is one exception – in "Cash Truck Xmas Delivery", RTP is reduced from 96% to 94.05%. Despite this, the overall picture for Quickspin is much better than for many other providers at this casino.

• Artemis Vs Medusa – RTP 96.17%

• Big Bad Wolf Christmas Special – RTP 97.34%

• Big Bot Crew – RTP 96.51%

• Blue Fortune – RTP 96.57%

• Cash Truck Xmas Delivery – RTP 94.05% (normal 96)

• Polar Paws – RTP 96.84%

Wrapping up our review, I noticed the slots from Play'n Go. Unfortunately, the situation here is extremely disappointing. Prime Slots has significantly reduced RTP in all checked games from this popular provider. The most shocking is the situation with the legendary "Book of Dead", where RTP is reduced from 96.21% to 91.25%. Such large-scale reductions were found in all checked Play'n Go slots.

• Book Of Dead – RTP 91.25% (normal 96.21)

• Helloween – RTP 91.20% (normal 96.20)

• Holiday Spirits – RTP 91.21% (normal 96.29)

• Rise Of Olympus 100 – RTP 91.20% (normal 96.20)

• Sabaton – RTP 91.50% (normal 96.5)

• Viking Runecraft 100 – RTP 91.2% (normal 96.2)
