Picture a jewelry display case lit from behind, then split it into four windows that all spin at the same time. That's the trick Gems Gems Gems pulls off, and it's why this 2009 SG Digital title still gets pulled out of the Light & Wonder catalogue every now and then. The chunky “GEMS GEMS GEMS” lettering across the top hasn't aged a day, honestly. Below it sits a main 5×3 grid full of rubies, sapphires, emeralds, citrines, amethysts and clear diamonds, all glowing against deep navy. Three compact mini grids stack beneath, repeating the same gem icons in miniature.
Here's where the Super Multi-Pay mechanic earns its name. Each base spin runs four reel sets at once, 20 paylines each, 80 lines firing simultaneously. Any Wild or Feature symbol that lands on the main grid gets mirrored onto all three mini grids automatically. So a single stacked Wild up top? It replicates three more times and can paint payline hits across every set in one go. Bet range is $0.40 to $200, and there's a hard $250,000 cash ceiling sitting on top of everything.
The Free Spins trigger inherits the same multi-grid quirk. Three or more Feature scatters on one set buys you 10 spins. Hit Features on two sets in the same base spin and you double up to 20. Three sets together gets 30. Four sets at once? The dream draw at 40 spins. The multiplier scales right alongside the trigger count and stays locked for the entire round, climbing up to 4x when all four sets fire together. A multi-set trigger also pays 2x your total bet on entry, while a single-set trigger pays 1x. Retriggers add another 10 spins but won't reset that multiplier.
And here's the catch worth flagging. Once you're inside the bonus, only one reel set runs. The whole multi-grid spectacle that makes this game interesting disappears for the round you were hoping it'd matter most. Free spins use a denser alternate strip with heavier Wild and Feature concentration on a single 20-line grid. Is it still a decent feature? Sure, especially at 4x locked. But the visual personality flattens out completely.
One more thing: the 94% RTP is low. Even by 2009 standards, that's on the stingy end. Wild subs for everything except Feature, and the Feature scatter has its own tiny line pays (1x for four-of-a-kind, 2x for five). A genuine curio.
