Hydra’s Lair slot game online

In Evan Carrington's GCCans review, Hydra’s Lair is described as another quality release from Mascot Gaming. Its base game offers entertainment, while the infinite free spins round can also trigger a highly lucrative Hydra feature.

Theme and storyline

Hydra’s Lair uses a fantasy setting centred on a beast called a Hydra. According to the story, anyone who slays the creature's head is brave and destined to find riches. Do you have the nerve to defeat this monstrous being and pursue big wins along the way?

Graphics, sound and animation

The graphics and animations in this release from Mascot Gaming meet a good standard. Although the environment is dark and atmospheric, the reels feature plenty of bright symbols. Animated firebugs on either side add some illumination to the beast's lair. The soundtrack is spooky but calming as you spin the reels.

How to play

The game uses a 5x4 reel layout with 20-fixed paylines. As in most online slots, you need 3, 4, or 5 matching symbols on one payline. The first symbol must appear on the first reel, followed by the others on successive reels along that payline.

There are 9 paying symbols, along with a wild and a scatter. The wild substitutes for every symbol except the wild itself, while the scatter helps activate the main bonus feature. Helmet is the highest-paying symbol, awarding 25x for a 5-symbol combination. The other theme-based symbols offer additional high payouts, whereas the playing card suits sit at the lower end.

Here are the payouts for 5-symbol winning combinations:

• 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: Landing a scatter symbol on each of the first and last reels activates infinite free spins. The unlimited spins continue until you land two scatter symbols, which ends the feature.
• The Hydra Feature: This feature is available only during the free spins round. When a Hydra wild symbol lands, it changes all adjacent symbols into wilds. A symbol beside multiple Hydra symbols receives a 1x multiplier for each one, while symbols changed to wild by Hydra also receive a 1x multiplier. Additionally, two adjacent Hydra symbols become wild symbols carrying a 5x multiplier.
• Risk & Buy Feature: This option is available on all spins, whether you lose or win. After a win, you can gamble the amount won to trigger the free spins feature. After a loss, you can use it to buy the free spins round at the offered cost.

Bet sizes, RTP and variance

Hydra’s Lair has a 95.19% RTP and high variance. Bets range from 0.02 to 4.00 per spin.

Conclusion

Hydra’s Lair does not offer the warmest slot presentation, yet its principal bonus round is the standout attraction. In theory, the free spins could continue indefinitely, though the feature must eventually conclude. During the round, the Hydra feature can also increase potential payouts. Overall, this is a good casino game for players seeking high-variance action, worthwhile bonus features, and entertaining gameplay.
