Endorphina’s Undine’s Deep takes us beneath the waves in search of mythical creatures and sunken treasures. Uncover the secrets of the mermaids and you’ll unlock a high-potential free spins bonus where all of your wins are multiplied.
That’s not all this slot has to offer either. VIP players will love the double-your-money gamble feature that can lead to massive payouts! We managed five correct picks in a row and eventually swam away with a €2,000 win. The question is: can you hold your nerve and go all the way?
Minimum / Maximum Bet:
Scatters, Wilds, Free Spins, Multipliers, Gamble Feature, Feature Buy
Wilds: The Goldfish Wild substitutes for all regular paytable symbols. Also, it doubles any payout when it’s part of a winning combination.
Gamble Feature: Undine’s Deep comes with a gamble feature that gives you a chance to double your winnings up to ten times. Simply choose one of the four face-down cards and if you beat the Dealer’s card, you win.
Scatters: Land three or more Mermaid Scatters on the same spin to trigger 15 free spins on Undine’s Deep. This symbol also awards a fixed payout worth 2x, 5x, 20x or 500x your bet whenever two, three, four or five appear, respectively.
Free Spins & Multipliers: Upon triggering the bonus, you’ll receive 15 free spins and all wins benefit from a 3x multiplier. It’s also possible to retrigger the feature by landing three more Scatters. This adds another 15 free spins to your remaining total. Aside from that though, the gameplay remains unchanged from the base game. There are no additional features like extra Wilds. Nevertheless, the 3x multiplier can lead to some immense payouts.
We hit several bonuses but one in particular had us on the edge of our seats. We retriggered this feature four times and ended up with 75 free spins. Our total winnings? €2,903.50! An amazing win for a €5 bet, right?
Bonus Pop Feature Buy: You can purchase entry to the free spins bonus for the cost of 102x your current bet.
Undine’s Deep is an entertaining adventure on the high seas, where mystical creatures can lead to some great payouts. The problem, however, is that the game is very basic on the whole. Its limited set of features may entertain for a while, but we don’t think the game packs enough of a punch to keep you coming back for more.
Still, if you’re the type of player who wants a stripped-back slot game, Undine’s Deep could be the game for you.
Fishin’ Frenzy Megaways by BluePrint: If you’re looking for a similar take on the ocean theme, Fishin’ Frenzy Megaways (95.02% RTP) has a lot to offer. There’s a 10,000x maximum win up for grabs, the Megaways mechanic makes each spin unique and you can reel in high-value fish during the free spins bonus – we won over ₹38,000 on just one spin thanks to the fisherman’s hard work!
Pearls of India by Play’n GO: Packed full of bonus games, free spins and a gamble feature, Pearls of India (94.87%) is a great fit for high-rolling bonus hunters.
