Lords, ladies, and gentlemen, along with the yet-to-win-an-award site, Casinos.com, I present you the 13th Trial Hercules Abyssways slot by Play’n GO. This is a Greek Mythology slot game, which can only mean one thing. Yes, for this special slot review, we are joined by the egotistical megalomanic who just happens to know everything there is to know about Greek Mythology slots, the Mighty Hercureels.
Along with his appearance as a guest speaker and game reviewer, we also present the free-to-play online casino game in its demo format. Practice and play the free game before you head into the online casinos in the hopes of winning real money.
Now, without further ado, given that this is one of the worst intros ever, please give it up for your star player, all the way from the newly sponsored Red Bull Mount Olympus, here’s the Mmmmighty Hurcureels.


The 13th Trial Hercules Abyssways slot has a high volatility setting with an RTP of 96.20%. The maximum payout you can win is 60,000 times your betting price. Now, bets can start as low as $0.10 per spin but rise to a max cost of $100. Betting at this higher end can result in a $6,000,000 winning jackpot.
To win, you must land three or more symbols upon adjacent reels, two or more if it’s the Hercules symbol. The layout of the online slot comes with 4,096 ways to win, but because of a special feature, the expansion of reels can offer up to 46,656 ways. Many other in-play features can benefit you should they land on the rows and reels.

First, our contractual thanks to Mighty Hercureels for being our guest reviewer for 13th Trial Hercules Abyssways. He didn’t fare well, but he enjoyed the game enough to want to play it again. The slot isn’t as grand or epic as the look and title would suggest. There’s very little to this game that is new and fresh. It’s a ‘been there, done that’ kind of slot, and Play’n GO has been making more of these lately.
