The Big Catch is a fishing-themed video slot released in June 2021, and it keeps the familiar 5-reel, 3-row grid with 10 fixed paylines. The default RTP is 95.32%, which sits below the original's 96.12% headline, so it's worth checking the paytable before you commit real money. The max win is capped at 5,000x your stake, and volatility runs medium. The signature twist is a collect-and-upgrade mechanic: land four Fisherman Wilds inside the free spins and the lowest-value fish gets promoted a tier, while you're handed extra spins to keep the round going.
That single rule is what separates this game from the base slot. You're not just waiting for one wild to sweep the reels. You're stacking wilds toward a threshold that changes the paytable mid-feature.
It's a modest sequel in headline terms. However, the upgrade loop gives the free spins a sense of progression that the original doesn't have, and that's the reason players keep coming back to it.
