How to play Mega Don mobile slot

These deep dark water hide three hungry sharks who will pop out of nowhere in this Mega Don slot, eat the symbols on the reels and upgrade you to win big in the most surprising way.

The Mega Don is a 5-reel video slot machine with up to 1024 ways to win and three high-paying symbols: the Leopard Shark, the Hammerhead Shark, and, of course, the Great White Shark. The three of them swim under the true blue reels, ready to jump up and eat the little fish on the reels.

Don’t underestimate the teeth of this Mega Don online slot, from the wild to the symbol upgrade; this is a very volatile game with a huge top win of 10,000x your bet thanks to the symbol upgrade feature in both the base game and the free spins.

The RTP can vary widely on this Play’n GO slot game, depending on which casino you play. Make sure you find the Mega Don slot at 96.20% rather than 84.24%, as the lower rate makes this almost unplayable.

The hunters of the sea become the hunted

The main feature of this Mega Don mobile slot is the symbol upgrade feature. Randomly the game will pick one of the lower-paying symbols to transform into one of the three sharks.

Visually this is always fun to watch, as the Leopard, Hammerhead, or Great White will jump out of the ocean and eat the trembling fish on the reels. Small details like that elevate this casino game studio from the others.

The Barracuda and the Marlin are the next high paying, but you really want the far more low-paying prey to transform: there is (naturally) more of them on the reel. The low-paying symbols are The Box Fish, Puffer Fish, Minnow, and Shrimp, all wonderfully animated.

Mega Don has a top win of 10,000x your stake

To win this Mega Don slot’s top win, you must get the Great White Shark symbol on all 5×4 reels and 1024 ways to win. You do that in the free spin bonus.

During the bonus games, you’ll play 6 to 12 free spins where 1 to 3 symbols will always be upgraded to one of the shark symbols. When you retrigger the bonus, more low-paying symbols can be transformed, leaving you with very few prey and just big bad predators on the reels.

What we like about this Mega Don online slot is that while it is quite volatile, the symbol upgrade features come often both in the base and free spins, allowing fast energy that we loved. We were at the edge of our seats the whole time.

If you enjoyed the Moon Princess 100 slot or the Raging Rex 2 review, you must take a few spins on this Mega Don. Is it dangerous? Absolutely. But with danger comes lots of fun and excitement.

Symbol Upgrade: Up to 3 small fish symbols may be randomly selected to upgrade into any one of the three high-paying sharks - the leopard, hammerhead, or great white shark.

Mega Don Review Conclusion

We were surprised by how much we enjoyed this 1024 ways to win Mega Don slot, but the quirky graphics, fun, animations, and top wins made us grin like sharks.

It's not a perfect video slot on mobile - getting more than one symbol upgrade in the free spins can feel difficult, though we've done it enough times to know it's not impossible.

You have a low minimum bet of 0.10 a spin, allowing you to start small and grow your budget as you hunt down those Mega Dons and max win of 10,000x your bet.

And unlike the Derby Wheel slot, it has lower volatility but a much higher top win. That's a powerful but dangerous combination for powerful and danger-seeking gamblers at all good online casinos.
