100% up to $100 monster bonuses at Grande Vegas Casino

In the midst of its Halloween celebrations, Grande Vegas Casino has launched its new Monster Mayhem online slot machine and is giving players a bonus of up $100 just to try it out.

The new 50-line slot machine features a giant reptile making its way through a city, and an enormous pink rabbit and a hulking orange cat stomping and crunching their way through the urban jungle. The giant, animated city beasts “Smash” and “Crash” trigger the re-spin feature, with the reels spinning up to 10 times. During re-spins, prizes are multiplied by 1 in the first re-spin, by 2 in the second, by 3 in the third and so on.

To claim their 100% up to $100 bonus, players just enter the casino bonus code “MONSTERMAYHEM” when they make a deposit. This new casino bonus is available only until October 21.

Grande Vegas Casino offers more than 300 casino games to choose from, including slots, blackjack and roulette. Several slot machines with progressive jackpots over a million dollars are among the most popular. Someone playing Jackpot Pinatas could win nearly $1.7 million. On Aztec’s Millions the progressive jackpot is currently over $1.3 million. The Midlife Crisis/Shopping Spree jackpot is just over a million and Cleopatra’s Gold is over $275K for a total of over $5.2 million in the jackpot pool.
