Alchemy Gold Slot by PG Soft

Every cascade in Alchemy Gold runs a two-part cleanup. First, winning symbols stay locked in place. Then the remaining non-winning symbols dissolve off the grid, and the win multiplier ticks up by one. New symbols drop into the empty spaces, and if they connect with the sticky winners to form another cluster, the process repeats - lock, dissolve, increment, refill. That multiplier doesn't reset between cascades within the same spin. A chain that runs five or six deep applies x5 or x6 to the final payout, which changes the math on what looks like a modest cluster hit.

Gold frames add a second layer to all of this. Random symbols get outlined in gold at the start of any spin - no trigger required, no cost attached. If a gold-framed symbol is part of a winning cluster, it converts into a Wild after that cluster resolves. So a low-value symbol that happened to catch a gold border and sit adjacent to a matching cluster suddenly becomes a Wild for the next cascade, bridging gaps between symbols that wouldn't have connected otherwise. The frames appear on different positions every spin, and the number of framed symbols varies, so some spins hand you three or four potential Wild conversions while others give you one in a dead corner. It's the kind of mechanic that makes you watch the frame placement before you even look at what symbols landed.

Three scatters award 10 free spins, each extra scatter adds 2 more. The multiplier carries over between spins during the bonus - it starts at x1 on the first free spin and climbs with every cascade across the entire round, not just within a single spin. A cascade on spin 3 that pushes the multiplier to x4 means spin 4 opens at x4 before anything drops. Retriggering extends the run further. Between the sticky winning symbols, the gold-to-Wild conversions, and a multiplier that never resets until the bonus ends, the free spins compress most of the 5,000x ceiling into those 10-plus spins.
