The Magic Cauldron - Enchanted Brew Slot by Pragmatic Play

Every winning cluster that explodes during a tumble feeds a counter. Hit 25 collected symbols and one random modifier fires. Hit 50, two fire. All the way up to 125 for the full set of five. The counter resets each new paid spin, so the entire collection happens within a single cluster pay tumble chain - long chains with big groups fill it fast, short ones might not reach the first threshold at all.

The modifiers do specific, sometimes odd things. Befuddlement converts all high-pay symbols into low-pay ones (yes, that sounds bad - it consolidates the board for bigger clusters). Invisibrew removes every low-pay symbol entirely. Enlarging Ale stamps a 3x3 or 4x4 block of matching symbols onto the grid. Balm of Transfiguration picks a random low symbol and converts every instance of it into a random high symbol. Each one fires after the current tumble finishes resolving.

Fifth slot in the modifier lineup is always premium. Potion of Darkness wipes all low-value symbols and refills exclusively with highs. Unicorn Dust places 3-4 Unicorn Wild symbols carrying starting multipliers of 1x or 2x. These Wilds stick around through wins, shift to random adjacent positions after each tumble, and grow by 1x every time they help form a cluster. They cap at 20x each. When multiple Unicorn Wilds land in the same winning group, their multipliers add together - three at 5x, 8x, and 12x means a 25x total on that cluster.

Two more mechanics sit underneath all of this. Elixir Wilds drop 4-8 Wilds onto the grid after any paid spin that produces zero wins, so dead spins aren't always dead. Moon Seed marks every instance of one random low symbol at the start of a spin, and if a group of 5+ marked symbols connects into a win, two Wilds appear in the spaces they leave behind. No bonus round, no free spins, no fantasy-game jackpot wheel. The 7x7 grid and its modifiers are the whole game, and 5,000x is the ceiling.
