Major Millions is a typical old-school-style jackpot slot that was released by Microgaming back in the year 2000. This makes it one of the oldest jackpot slots still in existence, however, this war-themed jackpot slot has stood the test of time and continues to greet repeat customers. The 5 reels, 15 paylines online slot has been modelled on the original land-based version.
The Major Millions video slot game focuses purely on the progressive jackpot which seeds at $250,000. Although not feature-rich and only managing an 89.37% RTP, the jackpot game does offer wilds, win multipliers (3x), high paying scatters, a wild ‘fixed’ jackpot of 8,000x stake and a low volatility rating.
In collaboration with Triple Edge Studios, Microgaming released the Sisters of Oz WowPot slot game in 2020.
