40 Sevens - Diamond Treasures

40 Sevens – Diamond Treasures puts its feature set front and center with the Diamond Treasures side game, where collected diamonds fill a chest that unlocks a 4x1 multiplier spin with random rewards up to x9999. As play unfolds across stacked reels, Diamond Wilds substitute on paylines while 3, 4, or 5 Stars trigger 10, 15, or 50 Free Games, turning the Seven into an additional Wild and giving the base setup much more punch. It reads like a classic sevens slot built around layered upgrades rather than nostalgia alone, with stacked symbols and the boosted Free Games doing most of the heavy lifting from spin to spin.
