Undines Deep Slot

General Overview

Undine is a water nymph or, in other words, a mermaid. The Czech-headquartered games developer Endorphina decided to capitalise on the mythical theme by creating a 10-line video slot called simply Undine’s Deep. The majestic theme is pretty much the only element that separates the slot from its many counterparts. It’s played at a high variance and has plenty of rewarding features that give it a reason to try. You can do that for free or for real money at select online casinos, some of which accept Bitcoins.

Features and Bets

The action happens deep below the sea, with green seaweed and seahorse swimming next to the reels. In addition to the beautiful atmosphere designed by adept artists at the up-and-coming iGaming company, Undine’s Deep comes with the usual bet selectors.

The coin size ranges from 0.01 up to 5 credits, and together with the coins selector that ranges between 1 and 100, players can set a comfortable total stake easily. The only drawback is that the game displays it as coins, and not as credits. And those who prefer even higher leverage can deselect the default 10 lines as they wish.

Symbols and Bonuses

Starfish, jellyfish, seahorse and gold fish are all part of the Undine’s Deep symbols. Granted that you wager 1 coin per line, the most you can win for any 5 of them on a line is 750 coins.

The Gold Fish symbol is Wild, so it can replace any other icon to help form a winning combo. If you trigger 5 of such on a line, the reward will be at least 9,000 coins. What’s more, all wins with the Wild are doubled.

The Free Games bonus with 15 freebies is won with 3 or more of the Undine or Mermaid icons. On their own, they pay up to 5,000 coins (5-of-a-kind). What’s more, the spins have an x3 multiplier, so all wins are triple their original value. Whether this applies to wild combos too isn’t readily stated in the paytable.

Once you trigger the Free Spins bonus, the possibility that you will re-trigger it is fairly high. However, since it’s played at a high variance, don’t expect too many wins during the round.

Some other 10-line video slots from Endorphina include titles like Temple Cats, Chimney Sweep, and the Armenian ancient kingdom themed Urartu.


Undine’s Deep is a mermaid-themed online slot from Endorhpina. It has 10 pay-line, 5 reels and lots of exciting features. Enjoy doubling Wild icons that appear as gold fish, and trigger 15 Free Games with an x3 multiplier with 3 or more Undine symbols.
