Play Hydra’s Lair online

In Evan Carrington’s Casino Ideal review, Hydra’s Lair is presented as another strong release from Mascot Gaming. The base game offers entertainment, while the infinite free spins round can also trigger a potentially lucrative Hydra feature.

Theme and Storyline

Hydra’s Lair is set in a fantasy world centred on a beast known as a Hydra. The story says that anyone brave enough to slay one of its heads is destined to find riches. Do you have the courage to face this monstrous creature and seek big wins along the way?

Graphics, sound and animation

Mascot Gaming’s graphics and animation are well executed in this release. The setting is dark and atmospheric, but bright symbols stand out on the reels. Animated firebugs on either side bring a little light to the beast’s lair, while the spooky yet soothing soundtrack accompanies each spin.

How to Play

The game has a 5x4 reel layout and 20 fixed paylines. As with many online slots, a payline win requires 3, 4 or 5 matching symbols. The first symbol must land on reel one, with the remaining symbols following on consecutive reels along that payline.

The game has 9 paying symbols, plus a wild and a scatter. The wild substitutes for any symbol other than itself, while the scatter can trigger the main bonus feature. The helmet is the top-paying symbol, awarding 25x for a 5-symbol combination. Other themed symbols also offer high payouts, while the card suits pay less.

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 on both the first and last reels activates unlimited free spins. The round continues until two scatter symbols land, bringing the feature to an end.
• The Hydra Feature: This feature is available only during free spins. When a Hydra wild lands, it turns all adjacent symbols into wilds. A symbol next to multiple Hydra symbols gets a 1x multiplier for each one; symbols Hydra converts to wilds also receive a 1x multiplier. Two adjacent Hydra symbols also become wilds carrying a 5x multiplier.
• Risk & Buy Feature: This option can be used after either a win or a loss. After a win, you can gamble the amount won for a chance to trigger free spins. After a loss, you can pay the offered cost to buy the free spins round.

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 may not have the friendliest presentation, but its main bonus round is the game’s highlight. The free spins could, in theory, continue indefinitely, although the feature must eventually end. The Hydra feature can also boost potential payouts during the round. Overall, it is a solid casino game for players looking for high-variance action, worthwhile bonus features and entertaining gameplay.
