Mega Don

For an online slot that has real bite, check out Mega Don by Play'n GO. With a nod to the now-extinct Megalodon, this game takes players into the deep to fish for potential cash prizes. There are lots of sharp teeth and some terrifying predators waiting on the reels, but there's also the chance to win up to x10,000. 

Slots which are based in the water are pretty standard, but this game is a very long way from the benign waters of Fishin' Frenzy and co. An array of fierce-looking fish appear on the board, so these aren't waters that anyone will want to paddle in! 

The gameplay is set on a transparent 5x4 grid which includes 1024 ways to win. As more experienced players will know, this means no traditional paylines, with symbols just matched on adjacent reels from left to right. The betting range is comprehensive, stretching from 0.10 to 100.00. The RTP is above average at 96%, and the volatility is high, which means you should get fewer wins, but higher values when they do land. 

The design of this online slot is simple yet effective, with the reels appearing to float directly in the water. Looking down from above, players will be able to see lots of shadowy shark figures swimming around below, providing a terrifying chill! 

All of the symbols on the board are fish and shark-themed; there are no playing cards in this slot. The low pays are made up of a variety of small fish while the premiums are just sharks.  

There is also a wild symbol, and this can land to replace any of the regular symbols, enabling more matches to be made. 

Mega Don has a couple of handy bonus features, mainly based on transforming symbols.  

The first of these is Snack Time, a feature which is triggered randomly. Up to three different fish can be elected; these are replaced by high-value symbols when they land, giving the potential for bigger wins.  

The second is Shark Feast, where landing three scatters will unlock the free spins bonus. The number of scatters you land determines how many free spins you receive and how many symbols are upgraded.  

The free spins bonus can be retriggered by landing more scatters. At this point further symbols are upgraded again, making it theoretically possible to change all six symbols into a single shark symbol. This is the way to get a huge win and make a real splash!

Mega Don is an online slot from Play'n GO which is visually very attractive, taking players into deep water for the action. There are a few extra features to make play more interesting but compared to other slots, it's pretty simplistic. This means it will suit casual players, but the x10,000 potential top payout with the high volatility will appeal to those hunting the bigger prizes too.
