Jumbo Safari Slot by Pragmatic Play

Eight animals sit above the reels during the bonus round, each carrying a prize between 20x and 1,000x. The gorilla holds the crown - literally - with the top 1,000x value, while the frog sits at the bottom with 20x. Land five matching animal symbols on any spin to collect that animal's prize and move on to the next target.

The twist is in what happens when you don't win. Every spin that fails to complete a five-of-a-kind animal match pushes all eight prize values higher by 0.2x to 4x. So a long dry streak during free spins actually works in your favor - by the time you finally land a set, the payout might be significantly larger than its starting value.

Free spins begin with a chest selection screen. Pick one of eight chests to reveal an animal, and that animal becomes stacked across all reels for the entire bonus round. This stacking makes five-of-a-kind hits far more likely than in the base game. You get 15 spins for three scatters, 30 for four, and 50 for five.

And if luck completely abandons you during the bonus - no prize collected at all after all your free spins - the game runs one final bonus spin that guarantees a payout. The chosen animal lands, and you walk away with whatever its current (escalated) value is. It's a safety net that means the bonus round can't truly blank.
