Hellboy online slot game
The Hellboy online slot combines free spins and extra wilds with wilds that double wins, a bonus game, scatter multipliers and high-paying symbol combinations. The original review describes bets of up to 200 coins per spin, or penny-style play using 1 line at 0.01 per spin.
Theme and Storyline
The story follows the half-demon Hellboy and characters from the animated cartoon adaptation of a film franchise that became an epic movie earning millions of dollars. In the game, Hell Boy sets out to recover the Hidden Relic of Power.
Graphics, sound and animations
Released in 2010, the game shows its age in the bulky reels and relatively simple symbol designs. Even so, Hellboy continued to appear at online casinos offering Microgaming video slots. The original review also called Hellboy one of the most popular slots among players; this is an editorial description, not a current popularity ranking.
Animations are built into the symbols, while the bonus game features more advanced graphics. On that basis, the original review still considers Hellboy a modern slot.
The review also commends the sound effects, observing that the developers created audio suited to the theme.
Top Casinos to Play Hellboy:
Gameplay
The Hellboy online slot has a 5x3 reel grid with 20 paylines. The original review suggests that landing one of the higher-paying symbols could be rewarding, given the large multipliers. A wild doubles any win it contributes to, while a scatter pays 500x, 25x, 4x, or 2x the ‘Bet Max’ value.
The Hell Boy wild logo pays 10,000 coins when 5 land on a payline. Hellboy, The Blood Queen, Ben Daimio, Lobster Johnson, and Professor Boom pay 5,000, 2,000, 1,000, 750, and 500 coins respectively for 5 on a payline. These prizes are denominated in coins, so with 10 coins in play, landing the Hell Boy logo could award 100,000 coins.
Bonuses and free spins
The Underworld Bonus starts when 3 ‘red fist’ scatter symbols land anywhere on the reels at the same time. The goal is to pass through 4 levels and find and secure the ‘Hidden Relic of Power’ in a hidden chamber. You get 1 pick per level, but beasts guard the route and must be battled for bonus rewards. Finding a team member along the way awards all prizes for that level. Choosing a blocked tunnel ends the mission.
Supermode is another feature that can trigger at random, awarding 10 free spins. Up to 3 random reel positions turn wild for the bonus. As no symbols trigger this random free-spins feature, it cannot be retriggered.
You can gamble every win by selecting ‘gamble’. Guess the next card’s colour to double the win, or its suit to quadruple it.
Bet sizes, RTP and variance
Set the ‘Bet Max’ value using the ‘coins’ box. At 1 coin per line, the total is 20 coins; the maximum is 10 coins per spin, or 200 coins per spin. The ‘coin’ -/ option sets each coin’s value from 0.01 to 0.25, and you can select 1 to 20 lines. With all 20 paylines active, a coin value of 0.25 and 10 coins per line, the total is 200 coins multiplied by 0.25, for a maximum cash bet of 50.00 per spin. At 1 line, 1 coin and 0.01 per coin, the minimum cash bet is 0.01 per spin.
The stated RTP is 96.49%, a theoretical long-run measure, not a guarantee of a particular result. The review describes regular base-game payouts and frequent bonus and free-spins rounds with the highest wins; these are observations, not assured outcomes. It therefore classifies Hellboy as a medium-variance game.
Conclusion
In Evan Carrington’s review for Casino Ideal, Hellboy is presented as a title that could suit both beginner and experienced slot players. The conclusion draws attention to its bonus feature, scatter multipliers, randomly triggered free spins and wilds that double wins in both the base game and free-spins round. It also notes the possibility of winning 100,000 coins at max bet, without suggesting that result is guaranteed.
