Atlantean Treasures Mega Moolah

Neon Valley Studios sets Atlantean Treasures Mega Moolah on the ocean floor, among broken columns and the murky ruins of a drowned city, with four ticking jackpot meters framing the reels from the moment the game loads. The base grid runs 5 reels by 3 rows across 10 paylines, and those lines pay in both directions - a combination reading left to right or right to left both count, which effectively doubles the ways a line can land.

The paytable leans on ocean life rather than cards: an orange starfish, a seahorse and a strand of fluffy seaweed cover the lower spots, a purple koi sits above them, and a pink fish fills the remaining mid-tier slot, while the '7' and BAR symbols top the table, worth 12x and 25x apiece for five matching symbols. A pink-haired mermaid works as the wild, standing in for every symbol except the jackpot trigger.

That mermaid wild does more than substitute. Landing on reel 2, 3 or 4, it expands to cover the whole reel and sets off a respin, with the expanded reel locked in place while the rest of the grid spins again. A second or third wild landing on the middle reels during those respins keeps the chain going, for up to three respins in total.

Running alongside the base game is the route to a four-tier jackpot. Pearl symbols - the Progressive Trigger Symbols - land at random on reels 2 through 4 and are banked in a clam beside the grid; collect enough of them and the reels hand over a spin of the Progressive Wheel, which guarantees one of the Mini, Minor, Major or Mega prizes, seeded at 10, 100, 10,000 and 1,000,000 respectively before each starts climbing toward its next win.

Away from the jackpot pool, the game plays out at 92.08% RTP with medium volatility and a 21.69% hit frequency - low even by jackpot-slot standards, but typical of how these Mega Moolah builds are priced. Stakes run from 0.10 up to 200 per spin, and the fixed-prize ceiling outside the progressive pool is 500x the stake.
