40 Sevens Diamond Treasures

40 Sevens Diamond Treasures from Apparat Gaming revisits the studio's established 40 Sevens formula with a shiny new side game bolted on. Played across a 5x4 grid with 40 fixed paylines, the slot keeps the classic fruit machine symbol set of grapes, melons and lucky sevens, all presented with a clean, reduced aesthetic that favours clarity over clutter. Stacked symbols fill the reels, and landing 3, 4 or 5 star symbols triggers 10, 15 or 50 free games respectively, during which the seven becomes an additional wild on top of the existing Diamond wild. This boosts win potential significantly thanks to the stacked reels already in play. The new Diamond Treasures side game runs alongside the main action, collecting glittering diamonds as they land on the reels into a treasure chest above the grid. Once the chest fills, it bursts open to reveal a special 4x1 multiplier reel, offering a spin for a random multiplier that can reach as high as 9,999x the stake. An optional side bet can be used to boost the odds of filling the chest faster. It is a straightforward, classic leaning slot with one genuinely exciting burst mechanic layered on top.
