Legend of Perseus Slot by PG Soft

Winning symbols collapse off the grid after each payout, and new ones drop in from above. Standard tumble loop. What makes it less standard is what happens when a big symbol - either 2x2 or 3x3 - lands and participates in a win. Each big symbol carries a multiplier printed right on its face: x3 to x5 for 2x2, x5 to x10 for 3x3. When that symbol connects with a winning combination, it gets destroyed like everything else in the cascade, but its multiplier gets collected into a running total displayed above the reels. Every win that follows in the same cascade chain pays at whatever the accumulated multiplier reads. Two big symbols winning in the same chain stack their multipliers together, so a 2x2 at x4 followed by a 3x3 at x8 means everything after that second collapse pays at x12. The multiplier resets when the cascade chain ends and a fresh spin starts.

Wilds substitute for everything except scatters and only show up on reels 2 through 6 - reel 1 never gets one. The six-reel layout runs 15,625 ways with five rows, so there's enough surface area for those oversized symbols to land without cramming the grid. Four scatters trigger 10 free spins, and each scatter beyond four adds 2 more. Free spins use the same big symbol multiplier collection, same cascade rules, same accumulation. No upgraded multiplier tiers, no persistent counter between spins. Each free spin resets the multiplier to x1 just like the base game does, so the 50,000x theoretical cap depends on stacking multiple big symbols within a single cascade chain during the bonus rather than building across several spins.

The simulated ceiling in a billion spins landed at 7,524x, which is modest for a game advertising 50,000x, but the multiplier math at least makes the path to bigger numbers visible. You need a long cascade with multiple big symbols winning in sequence, each one feeding its multiplier into the total before the next round of wins resolves. There's no buy bonus. Retriggering free spins is possible if four more scatters drop during the round, and that extended playtime with Greek mythology symbols - Perseus, Medusa, Zeus - gives the accumulation loop more chances to produce a chain worth remembering.
