If mythical slots are your thing, you've come to the right place. Get ready for an epic adventure, complete with Wild symbols, Multipliers, and the chance to increase your winnings with the Gamble feature.
While a lot of other games themed around mythical creatures go heavy on the background graphics (think lightning-struck temples and overflowing pots of gold), this Merkur Gaming title keeps things simple. The background shows a stormy scene over the sea, and the symbols are designed to fit in with the theme. Expect a few celebratory drum beats if you land a winning combination, but there aren't too many other sound effects.
The Zentaurus game grid is made up of five reels and three rows. The game has 20 fixed paylines – a little more than some other Merkur Gaming slots, which have just five or 10.
There are a few high-paying symbols to look out for, including the mountain, harp, and urn, while the A, K, Q, J, and 10 symbols award smaller payouts.
The Zentaurus symbol is the Wild, and it substitutes for all regular symbols, to help create winning combinations. Depending on how many Zentaurus substitutions are part of a win, you'll get a Multiplier of up to 16x.
Keep an eye out for the special coin symbols, which act as the Scatter. If at least three of them land anywhere on the grid, you'll get 10 Free Spins, with the Superspin feature. Winning symbols lock in place and other symbols respin, while wins increase.
Zentaurus has a Card Gamble and Ladder Gamble feature, both of which give you the opportunity to increase your winnings after each spin. The Gamble features are entirely based on luck, and if you don't feel comfortable risking all of your winnings, you can choose to cash some out along the way.
When you're ready to play, you can click on the coin icon at the side of the screen to select your bet amount. Choose from preset bets ranging from $/€/£0.05 to $/€/£10 per go. You can stand a chance to win up to 5,000x your stake.
The Return to Player (RTP) percentage of the game is 95.96%, which is very slightly lower than the average that we expect to see (96%). The game is highly volatile, which is great news, because it means that while you might wait a while to land a win, they tend to be quite generous.
We've played enough Merkur Gaming slots to know that the Gamble feature is pretty common, but Free Spins less so, so we were excited to see this bonus round. The theme isn't strong enough for us to really consider it a selling point, but the graphics are decent, and although the RTP is a little low for our liking, we were impressed with the high volatility. Overall, we think Zentaurus is a good game, although it's not exceptional.
