Major Millions is a Microgaming progressive slot machine which has 2 different versions. The new Major Millions 5-Reel version has 15 paylines and 15 coins. Its theme is America as a military super power. Players are offered a fixed coin size of $0.20, and the maximum bet per spin is $3. The Major Millions symbol is wild and can replace any of the 9 regular symbols to yield the 33 possible winning combinations. The Scatter Explosion symbol is a scatter and 3, 4 or 5 Scatter Explosion symbols on the reels multiply the total credits bet by 3, 10 or 50 respectively.

The global Progressive Jackpot is only activated when playing 15 coins at $3 per spin. It starts at $250,000 and is won when lining up 5 Major Millions symbols on the 15th enabled payline. The average Progressive Jackpot usually hits at $630,000 and very often goes over $1,500.000. The second highest payout is 8,000 coins for 5 Major Millions symbols on paylines 1 to 14. The 9 regular symbol combinations award lower payouts ranging from 2 coins for 3 Binoculars symbols up to 1,000 coins for 5 of the Major symbols on any payline.
