Olympus Gold Rush Slot by Evoplay

Every symbol in the base game is a coin waiting to be counted, but nothing gets counted until the bonus. Land four Bonus symbols across the central line and the reels convert into a hold-and-win round: three respins, each fresh coin resetting the count back to three, running until the spins dry up or all twelve cells fill. Ordinary Bonus Coins carry x1 to x4 your bet. The Heavy Coins are heavier for a reason, holding x5 to x9, and they've usually been sitting sticky on the reels since the base game, glued in place until the bonus finally opens. Change your bet and they vanish, so leave the stake alone if one is waiting.

The Black Hole is the piece that ties the round together. It carries no value of its own. When it drops during the bonus it reaches out and swallows every coin value and every jackpot already on the board into a single pile, so the more you've banked before it lands, the harder it hits. The four jackpots feed that pile too: Mini, Minor and Major sit on their own labelled coins that pay when they land, while the Grand at 1000x only comes from filling all twelve positions with Bonus symbols of any kind. There's also a Mystic coin, a purple lightning-wrapped Zeus that stays blank until the round ends, then flips into any symbol but a Heavy Coin. A Mystic Jackpot version guarantees one of the three lower tiers.

On top of all that sits the Olympus Gold Rush itself. At random inside the bonus, fire comets rain down and stamp x2 onto individual cells, and any comet that lands on an already-multiplied cell bumps it up by one more. Those cell multipliers hold to the end of the round and each coin's value gets boosted by whatever sits under it. The Ultra Bonus Game leans into this hard: it starts with the multiplier feature already live and firing more often, and it can hit at random on any base spin or be bought outright at 100x. The plain bonus buy runs 32x, cheaper but without the guaranteed multiplier layer.

The whole thing plays out under a scowling Greek Zeus on his marble throne, hurling a lightning bolt down over a grid of glowing purple cells trimmed in gold, sun-lit temples and a stone bridge fading into cloud behind him. If you've played Lucky Hercules or any Olympus coin-collector, the throne and the four-tier ladder will look familiar, but the Black Hole sweep is what gives this one its own rhythm.
