Does Rock ‘n’ Lock Pay Real Money?
BetMGM offers some of the best online slots for real money, with thousands of options, including the Rock ‘n’ Lock slot. If you play slots online from New Jersey, West Virginia, Michigan, or Pennsylvania, you can enjoy the thrill of winning real money.
How To Play Rock ‘n’ Lock
Rock ‘n’ Lock offers an intuitive gaming layout. The main controls are in a row on the bottom of the screen, and the 5×4 reel grid is front and center. An info strip just below the main controls offers access to the “Help” menu and the paytable.
Betting options range from $0.10 to $40, so there isn’t too much risk involved. Once you’ve set your bets, you can hit the “Spin” button or lock in your bet for up to 100 autospins.
Rock ‘n’ Lock Game Features
The game features a slick James Dean lookalike as the main character, representing the wild symbol. These symbols will substitute other symbols to help create winning combinations, but there’s a special bonus that comes with this handsome devil. Any winning line that includes one or more wilds will get an automatic 3x multiplier applied to the prize.
The Rock ‘n’ Lock slot runs a medium volatility model with a decent 95.69% return to player (RTP). Winning spins will come more regularly than most higher volatility online slots, and the prizes should feel slightly more consistent in range. The lower risk doesn’t necessarily mean lower rewards.
Rock ‘n’ Lock Bonuses and Jackpots
The main feature of this rock ‘n roll slot is its epic free spins round. Gold and platinum records appear on the reels and represent the scatter symbol. These also hold multiplier values that apply in the slot’s bonus round. The gold records have multipliers ranging from 1x to 5x, and platinum records could land with 7x, 10x, 12x,15x, 20x, and 25x multipliers.
Landing three or more scatters on the reels activates the Lock the Records bonus round, awarding respins equal to the number of scatters you landed to trigger the feature. This will generally be between three and five. Even if the scatters don’t trigger the bonus round, they could lock in for up to five spins to help you get to the bonus.
All the scatters you land, along with their multipliers, will lock on the reels. New scatters will also lock in and reset your respins count. The aim here would be to fill your reels with as many scatters as possible, with a special bonus added if you fill all 20 spaces. All multipliers will be combined and applied to your original bet when the round ends. And if you end the round with a full house, your win total will be doubled.
How To Win Rock ‘n’ Lock
With consistent gameplay mechanics throughout the base game, you shouldn’t have any trouble landing wins. But to maximize the game’s win potential, your best bet is to get into the free spins round and capitalize on all the multipliers.
Rock ‘n’ Lock Graphics and Design
The backdrop features a scene that could come straight out of the movie “Grease.” You’ll find big American muscle cars lined up outside of the neighborhood diner, with a solid gold reel grid lit up by fluorescent symbols and various elements from rockabilly culture.
The Evolution casino game production team didn’t skimp on the sound design, either. It features a subtle rockabilly jingle in the background and perfectly produced sound effects from slot machines and jukeboxes commonly found in diners at the time.
Rock ‘n’ Lock Symbols
The game has a unique take on the classic playing card symbols, offering them up in fluorescent lighting with an Art Deco style. The character symbols feature prominent elements from the subculture, including muscle cars, jukeboxes, microphones, and guitars. Check out the full paytable below:
