Legend of Hydra Power Zones Slots

Legend of Hydra

Legend of Hydra Power Zones slot is based around the many-headed serpent that is a feature of Greek and Roman mythology. The theme is brought to life with some amazing graphics and behind the reels, you can see an Ancient Greek temple on the shores of a stormy ocean. The theme extends to the high value symbols, which include the king and queen, and four more characters, each a warrior of some kind. The lower value symbols are different coloured gemstones.

How to Play 

The slot has 6 reels with 5 rows and 15,625 ways to win. Before you spin the reels, you need to set your bet using the ‘Total Bet’ control underneath the reels. When you are happy with your bet just click on the spin button to start the reels. There is also auto play functionality and a turbo mode to speed things up. 

You win payouts by landing enough matching symbols from left to right across consecutive reels starting from the leftmost reel. To help players form more wins, the crown is a wild symbol and it will substitute for all of the other symbols, except for the scatter symbol, to help and form winning combinations. The scatter symbol is a gold coin featuring the Hydra.  

Bonus Games and Features  

Many of the game’s features are centred upon the Power Zones. On any spin, each of the symbols, except the wild and scatter, can appear in a charged version denoted by a yellow ring of fire. They then turn the position they land on into a Power Zone. The Power Zones can connect with each other vertically and horizontally and landing a charged symbol next to an existing Power Zone will expand that zone. When a charged symbol lands inside a Power Zone, all symbols in that zone then transform to match the charged symbol.  

The slot has four Hydra features that can trigger at random on any base game spin. At first, just one of the features is unlocked and the other three are unlocked by filling the meter above the reels. The meter is filled by landing charged symbols in Power Zones. When a feature is unlocked, you receive a free respin with that feature active. The features are as follows: 

  • First – Up to 11 wilds are added to reels two to six 
  • Second – Up to 9 extra Power Zones are created 
  • Third – Up to 4 multiplier Power Zones with a x2 multiplier are created 
  • Fourth – Up to 3 Power Zones are added to the reels and all Power Zones are transformed into a mystery symbol 

The Mighty Hydra Free Games are triggered when enough scatter symbols land on the reels. Landing 3, 4, 5 or 6 scatters awards 12, 18, 25 or 50 free spins respectively. During the free spins, landing 2, 3, 4, 5 or 6 more scatters awards an additional 3, 12, 18, 25 or 50 free spins respectively, and this way more spins can be won indefinitely. When the free spins begin, the triggering scatter symbols will create Power Zones that remain in place for the duration of the round. At the end of the round, you receive a Mega Spin and all symbols in the Power Zones transform into a random matching symbol.  


All wins are multiplied by the coin value, which is equal to the total bet divided by 40. The slot offers a top payout of 28x for landing six of the king or queen symbols across the reels and all the other character symbols can payout up to 24x. All of the gem symbols can payout up to 20x.
