Wins Of Nautilus Megaways has 6 reels and offers up to 117649 ways to win. This is a typical reel set for a Megaways slot. This game’s payout table has ten standard symbols: four playing card icons, an old diving helmet, an anchor, a squid, a fish character, a mechanic, and the captain (a white-haired woman). Wins are achieved when players have three to six of the same icons on adjacent reels. Wins lead to avalanches. In other words, winning icons are replaced with new ones.
Symbols from winning combinations payout and disappear to let new symbols take their place. The avalanches can continue infinitely.
Countdown Bomb symbols land on the upper reel above reels 2 to 5. They enter with an Avalanche Counter, which is activated once the avalanche occurs in this round. The starting value stands at 1–4x and it decreases by 1x with each continuously triggered Avalanche. When it reaches 0, the symbol explodes and activates the Full Reel Wild option that features a multiplier of 2x the starting Avalanche Counter value. If there are 2 Countdown Bombs on the same column, their values will be added to each other.
Full Reel Wild is generated by the Countdown Bomb feature and can appear on reels 2 to 5. When there are 2 Wild Reels and they participate in a single combination, their multipliers are multiplied by each other.
The game has Scatter symbols titled “Bonus” that can appear on any reel and in any mode. They are collected in the Bonus Metre and when 3+ of them are collected, this activates 12 Deep Sea free spins. For 3 additional bonus symbols, players get 5 FSs. The option is followed by a 1x initial multiplier, which is increased by 1 each time an Avalanche happens.
