Arcane Woods Slot by Zillion Games

Golden butterflies drop onto the reels at random during base game spins, acting as wilds that substitute for everything except the unicorn scatter. Sometimes one lands, sometimes three or four appear at once - there's no fixed pattern. They don't carry multipliers in the base game, though. That changes in free spins, where each butterfly arrives color-coded: yellow ones hold x2, green ones x3, orange ones x4. When a multiplied wild sits inside a winning combination, the entire line payout scales by that multiplier. Two multiplied wilds in the same line add together rather than multiply, so a yellow x2 and an orange x4 on the same payline give x6 on that win.

Three unicorn scatters anywhere on the grid open the free spins round. The 162x buy option on the left side of the screen skips the wait and drops you straight in. Given that the max win sits at 473x, paying 162x for entry eats a third of the ceiling before the first spin even lands, which makes the natural trigger considerably more attractive if you're doing the math. Inside the feature, the base game's plain golden wilds are completely replaced by the multiplier variants - every butterfly that appears carries x2, x3, or x4.

A dense enchanted forest fills the background - gnarled oaks with twisted branches reaching over the grid, glowing blue mushrooms dotting the forest floor, purple wildflowers scattered along the grass. Two fairy characters stand on either side of the reels: pink wings and a crystal orb on the left, green wings and a glowing spark on the right. High-pay symbols are a crowned king, a queen with a golden tiara, and both fairies as reel icons. The lows are forest objects - a red lotus, a pink wildflower, a purple mushroom, and an acorn. Everything is painted in rich storybook illustration with heavy gold trim around the grid border and warm, saturated color on every symbol.
