Hydra’s Lair online slot game

Hydra’s Lair is another quality release from Mascot Gaming. While the base game delivers plenty of entertainment, it is the infinite free spins round that also lets you trigger a highly lucrative Hydra feature!

Theme and Story Line

The Hydra’s Lair video slot has a fantasy theme that is focused on a beast called a Hydra. The story says that whoever slays this beast's head is both brave and due to come into riches. The question is, do you have the guts to take down this monstrous being and land yourself some big wins in the process?

Graphics, Sounds, and Animations

The graphics and animations on this exciting release from Mascot Gaming are of a good standard. While the setting is dark and moody, you will see plenty of colourful symbols on the reels. To each side of those reels, animated firebugs help to bring a bit of light to the beast's lair. As for the audio, there is a spooky yet relaxing soundtrack that plays as you spin the reels.

The action takes place on a 5x4 reel format that consists of 20-fixed paylines. As with most online slots, you must land 3, 4, or 5 matching symbols on one of those paylines. The first symbol must land on the first reel with others landing on subsequent reels along that payline.

As for the symbols, there are 9 that payout, a wild symbol, and a scatter. The wild will substitute for all symbols apart from the wild while the scatter helps you to trigger the main bonus feature. The top-paying symbol is the Helmet which awards you 25x for a 5-symbol combination. You will find other high payouts from the remaining theme-related symbols. Playing card suits deliver payouts from the lower end of the spectrum.

The payouts for 5-symbol winning combinations are as follows:

  • Helmet - 25x
  • Skull - 12.5x
  • Goblet - 7.5x
  • Dagger - 5x
  • Sword - 3.75x
  • Heart - 2.50x
  • Spade - 2x
  • Club - 1.50x
  • Diamond - 1.25x

Bonuses and Free Spins

  • Infinite Free Spins: When you land a scatter symbol on each of the first and last reels, you trigger infinite free spins. You enjoy unlimited free spins until you land two scatter symbols to end the feature.
  • The Hydra Feature: You can only trigger this feature during the free spins round. When the Hydra wild symbol lands, it will turn all adjacent symbols wild. If one symbol is adjacent to multiple Hydra symbols, it receives a 1x multiplier for each of those symbols. The symbols that the Hydra turned wild also have a 1x multiplier applied. Plus, if there are two Hydra symbols adjacent to each other, they turn into wild symbols with a 5x multiplier.
  • Risk & Buy Feature: This feature is active on all spins whether you lose or win. If you win, you can gamble what you have won to trigger the free spins feature. If you lose, you can use the feature to purchase the free spins round at the cost offered.

Bet sizes, RTP and Variance

The Hydra’s Lair video slot has a 95.19% RTP and high variance. You can place bets of between 0.02 and 4.00 per spin.


Hydra’s Lair may not have the friendliest of slot themes but it does have a very appealing main bonus round. Theoretically, you could enjoy infinite free spins although they will have to end at some point. The Hydra feature also helps to up your payouts during that feature. All in all, this is a good casino game for those of you who like high-variance action, good bonus features, and enjoyable gameplay.
