At least one substituting goldfish in winning combination becomes a X2 win multiplier. More than three mermaids offer 15 free spins, wherein all winning combinations are subject to X3 win multipliers. After each winning combination, the players have the freedom to claim their payout by clicking “TAKE WIN” icon, or go to the side game via “TAKE RISK” icon. Immediately the card game shows up, the leftmost playing card flips to reveal its face value that is then compared with the face value of one of the four face down playing cards that the player has guessed; guessing a relatively lowly face value nullifies the current win, while guessing a relatively highly face value can progressively double the current wins until the X10 capping is attained. Undine’s Deep has a non-progressive jackpot amounting to $90000.00.

The instrumental in the background is melodious. The animated 3D graphics include: glowing symbols, idly flapping marine animals, and, in the background, ocean ripples, and bubble-emitting sea horses that nip in and out of fluttering green sea weed.
