Wolf Hiding Bonus Buy Slot by Evoplay

A moonlit cliff setting with wolves and enchanted forest backdrops frames the 5x4 grid. Mystery symbols appear in full stacks of four, covering an entire reel when they land. These stacks trigger the Hidden Feature: each Mystery symbol reveals either a regular symbol, a Wild, or a Full Moon symbol. After the reveal, any winning paylines are paid, and the next spin nudges the Mystery reel down by one position while all other reels spin normally. This continues until the Mystery stack slides completely off the grid.

The nudge mechanic means a single Mystery stack generates up to four consecutive semi-controlled spins. Since only the non-Mystery reels randomize, the revealed symbols stay locked in place and shift downward, creating evolving payline patterns across multiple rounds. Multiple Mystery stacks on different reels compound this effect.

Full Moon symbols within the Mystery reveal open a coin feature. Each Mystery position spins independently and lands on either a Coin symbol (carrying a bet multiplier between x1 and x2,500) or a Free Spins symbol. All Coin values are totaled and paid immediately. Free Spins symbols earned during Full Moon count toward the three needed to trigger the bonus round.

Free Spins start unlimited - reels two and four fill with Mystery symbols, and the round continues as long as Mystery symbols remain on the grid. A win multiplier begins at 1x and increases every time a Hidden Feature triggers. Since the nudge mechanic generates multiple Hidden Features per Mystery stack, the multiplier climbs steadily. Additional Free Spins symbols cause Mystery reels to nudge upward, extending the round further. The Bonus Buy option costs 32x total bet for direct entry. Changing your bet during base game resets any active Mystery symbols on the reels.
