Mystic 7s Slot by RealTime Gaming

Only 7s and BARs on the reels. No card royals, no themed pictures, just three tiers of sevens - purple with gold trim at the top, red and gold in the middle, green and gold below - and single, double, and triple BAR symbols printed on little hanging scrolls. The stripped-down symbol set keeps the paytable short and the math direct: everything pays, and the gaps between symbol values are wide enough that you feel the difference when a purple 7 line connects instead of a green one.

The base game runs 27 ways across three reels, but those folded panels on either side of the grid aren't decorative. Land the Free Games symbol and the layout unfolds to 7 reels wide, bumping the ways count to 45 for 10 spins. The expansion changes how wins build - seven reels of nothing but 7s and BARs means longer combination chains become possible, and a Ways Booster kicks in after winning spins to push the way count even higher during the round. Separately, a Jackpot Re-Spin triggers for a shot at the Grand (500x) or Major (250x), which sit in green gem-shaped badges above the reels throughout play. No buy bonus option here, so both the free spins and the jackpot respin come through natural triggers only.

The whole thing is wrapped in a Chinese temple pagoda - teal-green tiled roof curving upward, red wooden pillars, glowing blue lanterns flanking the grid, and red tassels dangling from knotted cords. Cherry blossom branches drift across a deep violet night sky behind it. The currency displays in yen by default, and the neon-pink logo in the corner leans hard into the lucky sevens motif. For a game with five symbols total, the 36,000x ceiling is steeper than you'd expect.
