Reef run online slot

Plunge into the ocean’s depths with “Reef Run,” an underwater-themed slot by Yggdrasil that promises an escapade amongst the most whimsical sea creatures. This slot takes you on a bubbly journey through the coral reefs, where fun and fortunes await.

The beauty under the sea is just one of the many attractive aspects of this amazing game from Yggdrasil Gaming. You can win big with different combinations and in many other ways; the choice is yours. With this game you will always win!

Reef Run Overview

Dive into the colorful underwater world of tropical reefs with Reef Run by Yggdrasil, one of the many exciting free Yggdrasil Gaming slots we’ve played.

The home screen immediately impresses with its animated sea characters and music, and it offers jackpots of up to 20,000 coins per line and a multiplier of up to x20 in its free spins feature.

This enchanting 5-reel, 20-payline slot is set against the backdrop of an underwater theme park, with a playful soundtrack and bubbly sound effects.

Although the number of paylines is fixed at 20, you can set your coin value between 0.01 and 5 coins and even customize your currency.

With Reef Run you can also adjust the volume of ambient sounds, the speed of the reels and the autoplay settings.

Level up

There are no wilds in this slot, but winning combinations occur frequently enough that you won’t miss them. The symbol to look out for is the free spins scatter symbol. Three of them will give you 10 free spins, four will give you 20 and five of one will give you an insane 60 free spins!

Now things get really interesting. Every time a symbol wins, it rises, i.e. H. if it wins a second time during the free spins, its payout will be multiplied by a factor of 5. The third time the multiplier increases to 10x, and if you land a fourth win with this symbol your win will be multiplied by 20x. If the symbol wins on two lines in the same game, the same multiplier applies to both wins.

During a run of 60 free spins, it is not impossible to increase all six symbols on the reels to 20x their payout value. If two, three, four or five scatter symbols appear you will even receive a few extra free spins during the feature.


Apart from the scatter symbol, there are only six symbols on these reels.

The puffer fish is the biggest payer, giving you 1,000, 200 or 30 coins for five, four or three matching symbols.

The crab pays 500, 100 or 20 coins, while the shrimp pays 400, 75 or 15 coins.

The octopus pays 200, 50 or 10 coins for five, four or three appearances.

The sea snail pays you 100, 40 and 5 coins, while the cheeky looking seahorse pays out 75, 30 or 5 coins.

All in all, this slot is very entertaining and offers some unexpected little surprises. If you let the reels stand still for about 15 seconds, you might see the flirtatious octopus waving its fan or the snail secretly winking at you. Reef Run is not just limited to laptops or desktops.

With its frequent wins, charming characters and a theoretical return of 96.4 percent, you can be sure of a lot of fun with this free slot machine!
