Nostradamus the Prophet Slot by Amigo Gaming

Deep purple mountains under a swirling cosmic sky, gold-framed reels, and a bearded prophet in dark robes staring out from the highest-paying position - the whole game leans hard into its 16th-century astrologer theme. Antique objects fill the premium tier: a wax-sealed scroll, a brass globe, a feathered ink quill, and a compass rose that doubles as the scatter. Three of those compasses anywhere on the grid award 8 free spins, and during those rounds only the premium symbols appear. No card ranks, no filler. That alone changes the math significantly, because the base game still runs standard 30-payline left-to-right wins with 10s through Aces filling most positions. Retriggering is possible inside the free rounds too, so the premium-only reels get extended play when scatters cooperate.

The Pin Win bonus is the other path. Six or more crystal ball symbols scattered across the grid lock in place and start a respin sequence - 3 initial respins, reset to 3 every time a new ball lands. Each crystal ball carries a bet multiplier value, and the colors matter: blue balls sit at the low end, purple in the middle, red at the top. The red ones carry values like 450x and even 9,000x at default bet levels. Fill all 20 positions and every bonus payout doubles with an x2 multiplier applied to the entire collection. Three jackpot tiers (Grand, Major, Minor) are tied to special crystal ball values inside the bonus. Pin Win triggers during free spins too, so the premium-only reel set feeds directly into higher crystal ball density. Wild crystal balls stack on reels 2 through 5 in the base game, substituting for everything except scatters and bonus balls, and those stacks are tall enough to fill full columns on the magic-themed grid's four rows.
