Let's start with the BGaming provider. After a thorough analysis of over 30 slots from this developer in Slingo, I am pleased to report that the casino does not lower RTP in BGaming games.

• Aloha King Elvis – RTP 94.98%

• Aztec Magic Megaways – RTP 96.72%

• Bob's Coffee Shop – RTP 97.1%

• Bonanza Billion – RTP 95.97%

• Candy Monsta – RTP 94.03%

• Clover Bonanza – RTP 95.97%

Unfortunately, the situation with Hacksaw Gaming games in Slingo is seriously concerning. The check revealed that the casino has significantly reduced the RTP in all slots from this provider.

• Alpha Eagle – RTP 92.25% (normal 96.26)

• Beast Below – RTP 92.25% (normal 96.2)

• Benny The Beer – RTP 92.28% (normal 96.18)

• Dork Unit – RTP 94.28% (normal 96.28)

• Rip City – RTP 92.21% (normal 96.22)

The analysis of Netent slots in Slingo revealed a troubling trend. The casino has lowered the RTP in almost all of the checked games from this well-known provider.

• 101 Candies – RTP 94.07% (normal 96.11)

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

• Beach Invaders – RTP 93.09% (normal 96.06)

• Dead Or Alive – RTP 92.06% (normal 96.82)

• The Wish Master Megaways – RTP 93.05% (normal 96.07)

The check of Nolimit City slots in Slingo revealed a highly unpleasant picture. The casino has significantly reduced the RTP in all checked games from this provider. Such a total decrease in RTP for Nolimit City games indicates an unfair approach by Slingo towards this provider and greatly worsens players' prospects.

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

• Blood & Shadow – RTP 92.04% (normal 96.13)

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

• Bounty Hunters – RTP 92.18% (normal 96.07)

• Buffalo Hunter – RTP 94.11% (normal 96.01)

• Das Xboot – RTP 94.04% (normal 96.03)

The analysis of Pragmatic Play slots in Slingo leaves a mixed impression. On one hand, the casino has reduced RTP in most of the checked games. For example, in "Buffalo King Megaways" and "Gates Of Olympus," the RTP dropped from 96.52% and 96.50% to 94.51% and 94.5%, respectively. On the other hand, there are exceptions – "Joker's Jewels" retained the original RTP of 96.5%. Nevertheless, the general trend of reduced RTP in Pragmatic Play games is cause for concern.

• Buffalo King Megaways – RTP 94.51% (normal 96.52)

• Gates Of Olympus – RTP 94.5% (normal 96.50)

• Joker's Jewels – RTP 96.5%

• Madame Destiny Megaways – RTP 94.5% (normal 96.67)

• Mustang Gold – RTP 95.54% (normal 96.53)

• Sugar Rush – RTP 94.5% (normal 96.52)

The situation with Push Gaming games in Slingo is highly alarming. The check revealed that the casino has significantly reduced the RTP in all slots from this provider. Such widespread RTP reduction in Push Gaming games greatly diminishes players' chances of winning and raises doubts about Slingo's fairness.

• Bison Battle – RTP 94.18% (normal 96.4)

• Blaze Of Ra – RTP 94.18% (normal 96.37)

• Boss Bear – RTP 94.34% (normal 96.38)

• Crystal Catcher – RTP 94.30% (normal 96.3)

• Deadly 5 – RTP 94.35% (normal 95.27 - 96.39)

• Fat Banker – RTP 94.45% (normal 96.43)

In examining Quickspin slots in Slingo, I again found an ambiguous picture. On one hand, some games retained their original high RTP. However, several other slots show noticeable reductions.

• Arcane Gems – RTP 96.05%

• Ark Of Mystery – RTP 96.53%

• Artemis Vs Medusa – RTP 96.17%

• Azticons Chaos Cluster – RTP 94.19% (normal 96.15)

• Big Bad Wolf Megaways – RTP 94.11% (normal 96.05)

The casino has significantly reduced the RTP in all checked games from this provider. Such a large-scale decrease in RTP for Red Tiger games seriously undermines trust in Slingo and greatly reduces players' chances of winning.

• Bass Boss – RTP 92.06% (normal 95.7)

• Dragon's Luck Power Reels – RTP 92.07% (normal 96.1)

• Dragon's Mirror – RTP 92.14% (normal 95.7)

• Rainbow Jackpots – RTP 92.1% (normal 96.15)

• Reel King Mega – RTP 92.19% (normal 96.17)

In most of the checked slots, there is a significant decrease, but the slot "3 Secret Cities" retained a high RTP of 96.5%. Once again, we see inconsistent treatment of games from another provider, which undermines players' trust in this casino.

• 3 Secret Cities – RTP 96.5%

• 9k Kong In Vegas – RTP 94% (normal 96)

• Book Of Armadillo – RTP 94.09% (normal 96.4)

• Money Train 4 – RTP 94% (normal 96.1)

• Temple Tumble 2 Dream Drop – RTP 94.8% (normal 94.80)

• Temple Tumble – RTP 94% (normal 96.25)

The analysis of Stakelogic games in Slingo revealed another ambiguous picture. Some slots retained their original RTP. However, most of the checked games show noticeable reductions. Such selective RTP reduction raises doubts about Slingo's fairness towards Stakelogic games.

• 9 Pyramids Of Fortune – RTP 93.87% (normal 96)

• Apes Of Doom – RTP 93.99% (normal 96)

• Arizona Diamonds – RTP 96%

• Bank Or Prank – RTP 95.78%

• Bison Blocks – RTP 93.82% (normal 95.9)

I am pleased to note that after checking more than 30 Thunderkick slots in Slingo, the casino demonstrated a fair approach to the RTP of this provider. All analyzed games retained their original high return rates.

• 1429 Uncharted Seas – RTP 98.6%

• Arcader – RTP 96.1%

• Babushkas – RTP 95.8%

• Barber Shop Uncut – RTP 97%

• Beat The Beast Griffin's Gold – RTP 96.14%

• Esqueleto Explosivo 2 – RTP 96.13%

The analysis of Wazdan slots in Slingo showed an overall positive picture. Most of the checked games retained their original high RTP. This indicates a fair approach by the casino to this provider's games. However, there are exceptions – some slots had their RTP reduced from 96.08% and 96.13% to 94.17% and 94.1%, respectively. Despite these isolated cases, the overall trend regarding Wazdan games in Slingo looks quite positive.

• 12 Coins Xmas – RTP 96.13%

• 16 Coins – RTP 96.18%

• Beach Party Hot – RTP 96.24%

• Black Horse Cash Out – RTP 94.17% (normal 96.08)

• Book Of Faith – RTP 94.1% (normal 96.13)

• Magic Spins Hold The Jackpot – RTP 96.17%

The situation with Yggdrasil games in Slingo raises serious concerns. The check revealed that the casino significantly reduced the RTP in almost all of the provider's slots.

• 10 Hot Hotfire – RTP 90.5% (normal 96)

• 10000 Bc Doublemax – RTP 90.5% (normal 96.5)

• 12 Trojan Mysteries – RTP 90.5% (normal 96)

• 3 Lucky Leprechauns – RTP 90.5% (normal 96)

• 3 Lucky Witches – RTP 90.5% (normal 96)

• Pumpkin Smash – RTP 96.2%

The analysis of Play'n GO slots in Slingo revealed a highly troubling picture. The casino has significantly reduced the RTP in all checked games from this provider to 91%. Such a total and substantial decrease in RTP for Play'n GO games indicates an unfair approach by Slingo towards this provider and greatly worsens players' chances of winning.

• Baker's Treat – RTP 91% (normal 96.03)

• Boat Bonanza – RTP 91% (normal 96.21)

• Captain Xeno's Earth Adventure – RTP 91% (normal 96.20)

• Sabaton – RTP 91% (normal 96.5)

• Testament – RTP 91% (normal 96.20)

• Viking Runecraft 100 – RTP 91% (normal 96.2)

After a thorough analysis of RTP in slots from various providers at Slingo, I must draw an unflattering conclusion: winning at this casino is nearly impossible. The overwhelming majority of the checked games have reduced RTP, which significantly lowers players' chances of winning. Only a small number of games, mainly from providers like BGaming and Thunderkick, retained their original RTP metrics. However, this is not enough to counteract the overall negative trend.
