Sapphire Supreme 7s

Kalamba Games leans on classic fruit-machine design for Sapphire Supreme 7s, dressing a 3-reel, 3-row cabinet in a gemstone theme of shimmering blue backdrops and metallic BAR and 7 symbols. The compact format keeps the pace quick while layering in several bonus mechanics rather than relying on the reels alone.

Five fixed paylines run left to right across the grid, so a win needs matching symbols to land on an active line from the leftmost reel onward. Multiplier symbols can appear on top of BAR and 7 wins, boosting those payouts by up to 10x, and a set of Sapphire collect symbols feeds two separate systems: landing three or more of them anywhere pays out the combined value shown on the symbols themselves as an Instant Win, while the total number collected over time unlocks tiered Cashpot prizes.

Bonus symbols handle entry to the free spins round, land three anywhere on the reels and the feature begins, awarding either 8 or 12 spins depending on which version is triggered. Multiplier symbols show up more often once the round starts, and hitting another three Bonus symbols during the spins retriggers the feature for more. Players who would rather buy in directly can do so for 40x the stake for the 8-spin version or 64x for the 12-spin version.

Sapphire Supreme 7s carries a 94.23% RTP and an above-average, high volatility rating, with a maximum win of 10,500x the stake. Stakes run from 0.10 to 100 per spin. The compact 3x3 grid and fixed-payline structure keep the base game simple, with the collect symbols and multiplier mechanic doing most of the work to lift a classic-style format into a game with modern bonus depth.
