Does Diamond Boost Pay Real Money?

The Diamond Boost slot game can pay out winnings in cash to players at BetMGM, the best online casino for slot gaming in the U.S., if they’re playing from one of the four states where BetMGM is licensed to operate, namely New Jersey, Pennsylvania, Michigan, and West Virginia.

How To Play Diamond Boost

  1. Click on the striped button on the left-hand side of the console to access rules, symbols, features, payouts, and volume control.
  2. Click the “Bet” button to choose your betting amount and the number of lines you’d like to play. The entry-level bet for this top online casino slot is a mere $0.05 per spin, and the maximum, $45 per spin.
  3. Click on the large “Play” button to get things rolling.

Diamond Boost Game Features

This online slot machine provides players with two interesting base game features. First, there’s the Wild feature. The 2X symbol acts as a wild for 7 and BAR symbols, except when three 2X symbols or a mix of 2X and diamond boost wild symbols align on a payline. A single 2X wild in a non-jackpot winning combination doubles the payout, while two 2X wilds multiply the win 4x. Similarly, the diamond boost symbol is wild for 7 and BAR symbols, unless any three diamond boost symbols or a combination of three diamond boost and 2X wilds land on a payline.

The second is the Diamond Boost feature. Landing a diamond boost symbol anywhere on the reels triggers the Diamond Boost Bonus, incrementally enhancing non-jackpot payouts. Each diamond boost symbol boosts paytable values once and awards an additional spin. 

During the bonus, diamond boost symbols behave as they do in the base game, stacking boosts up to 8x for substantial rewards. Players must balance the thrill of smaller immediate wins against the potential for significantly enhanced payouts as boosts accumulate. The bonus ends when no diamond boost symbols appear, with all wins calculated based on the paytable values at the start of each spin.

Diamond Boost Bonuses and Jackpots

While there’s no Free Spins feature, this online slots game offers one of three possible jackpot rewards through its Jackpot feature. The Jackpot feature in Diamond Boost offers three distinct tiers of rewards. The highest-tier jackpot is awarded by landing three diamond boost symbols on an active payline (10,000x), while the second tier is triggered by three 2X symbols (2,000x). 

A combination of any three mixed diamond boost and 2X symbols activates the third-tier jackpot (300x). This system provides multiple ways to win significant payouts, with each jackpot tier tied to specific symbol combinations on active paylines. For serious gamers, this makes it one of the best slot machines to play online.

How To Win Diamond Boost

The Diamond Boost slot game takes things back to a classic 3×3 grid layout, providing wins from left to right across a total of nine paylines. Players are aided in their quest for big wins by a Wild feature that can lead to quadrupled payouts, the Diamond Boost which can provide sizable payouts of 8x the bet staked, and the Jackpot feature that offers a total of three tiered jackpots, with the highest an impressive 10,000x the bet staked.

Diamond Boost Graphics and Design

The graphics and sounds of Diamond Boost combine to create a dazzling and exhilarating slot experience. The visual design is vibrant and luxurious, with the shimmering diamonds taking center stage, ensuring players are captivated by the potential for big wins. Subtle animations, like the sparkling trails of light following winning combinations, add satisfying visual stimulation. On the audio front, the game features an upbeat and glamorous soundtrack with catchy melodies that evoke the thrill of a high-stakes casino. Together, the visuals and sounds deliver a captivating and rewarding gaming atmosphere.
