Pompeii Megareels Megaways Slot by Pragmatic Play

Tumble wins play out normally at first - matching symbols vanish, remaining symbols drop, new ones fill in from above. The twist is Megareels: any reel that contained at least one winning symbol can randomly grow taller after a tumble, adding extra rows and inflating the total Megaways count mid-cascade. A chain that starts at a few hundred ways can balloon past 100,000 as reels stretch to their maximum height of seven.

Free spins award 15, 20, or 25 rounds for landing 4, 5, or 6 scatters. The multiplier system ties directly to cascade size - each win is multiplied by the total number of symbols that exploded in that specific tumble. A cascade clearing 30 symbols pays 30x the normal win value. Special reel sets during the bonus favor longer cascade chains, and the Megareels expansion keeps pushing ways higher with each tumble.

Two buy bonus tiers split the bonus into distinct experiences. The standard 100x option triggers free spins with a random 4-6 scatters. The 300x Double Multiplier option runs the same free spins round but doubles the dynamic multiplier - those 30 exploded symbols now count as 60x instead. Free spins cannot retrigger, so every round has a fixed length determined entirely by the initial scatter count.

Wild symbols land on reels 2 through 6 only, leaving the first reel without substitution. The scatter is base-game exclusive and does not appear during free spins.
