Frogs Gift Slot by Playtech

The gem-disc is the symbol that matters. A golden Aztec sun-disc set with a red gem, it works as the game's cash-and-bonus symbol, and enough of them landing lock in place to set off respins in a hold-and-win round. While those discs sit locked, the reels can hand you a Mega Reel spin, and that one guarantees a fixed jackpot. Four sit in meters across the top: Mini at 20x, Minor at 100x, Major at 500x and the Grand at 2,000x, which is as high as the game pays. No buy button, so the discs are the only way in.

The free games open with a choice. Trigger them and you pick your own setup: a longer run of spins, or a shorter one where the passion-flower wild carries fatter multipliers. It's a straight trade, quantity against punch, and there's no wrong answer, just how you like your variance. That purple flower with the gold emblem centre substitutes for every paying symbol and already brings a multiplier in the base game, so the free games are simply where it hits hardest.

The setting is a bright teal-and-green rainforest pool, a waterfall spilling behind the reels, mossy stone ruins half-swallowed by leaves, the whole scene named for the little orange poison-dart frog that lives in the pond. The paying symbols are rainforest wildlife: a fluffy golden lion tamarin, a spotted leopard, a black-and-white tapir, a blue-and-gold macaw and a shimmering blue morpho butterfly, sitting above jewelled A, K, Q and J royals. It looks the part. Under the jungle art, though, this is a fairly standard Rarestone hold-and-win build, the kind where the respin and its jackpot reel do the heavy lifting while the base spins mostly feed them.
