The Wild Depths slot has five reels, four rows, and forty paylines. All symbols pay left to right on active paylines, beginning with the first reel. Every spin, wagers vary from 0.20 to 100. Use the + and - buttons on either side of the spin button below the reels to modify your wager. Wild Depths has a return to player percentage of 96.48%, which is significantly above average for this type of online slot. The maximum win is 5,000 times your entire bet, which is less than some other Pragmatic Play offers but more than many slots from other developers.
The less valuable symbols are the 10, J, Q, K, and A. Five of the same symbol type returns between 1x and 1.5x the wager. Red starfish, purple seashell, and green seashell are the medium-paying symbols. Five of the same symbol type returns between 2.5x and 5x the wager. The icons with the highest payouts are a blue fish, a yellow fish, and an orange fish. Five identical symbols pay between 7.50x and 20x the wager. The game's wild sign is the bubble, while the clam with a big pearl is the scatter symbol.
The pearl in an oyster scatter symbol appears on all reels. Landing 3, 4, or 5 of them awards 2, 15, or 100 times the total wager and initiates 6, 9, or 12 free games. Whenever a wild symbol appears during free spins, the same wandering wild/respins cycle as described previously is triggered. Moreover, each time a respin occurs, the win multiplier increases by +1. This multiplier applies to all re-spin wins and resets at the conclusion of the re-spin sequence, when all wilds have left the grid. During the bonus round, scatter symbols remain on the reels, and landing three of them awards five more free spins with no cap.
