Coins of Oinks Slot by Betsoft

A crowned golden pig sits above a compact three-reel grid, surrounded by purple velvet and stacks of coins. Warm golds, deep purples, and cartoonish luxury - think cigar-smoking swine in a vault full of treasure. Betsoft built this one around their "Coins of" series formula, same family as Coins of Dragon and Coins of Halloween, but squeezed onto a smaller grid with only five paylines. For 50x your bet, the buy option drops you straight into the Hold and Win round with three respins.

The collect mechanic is where things get specific. Bonus coin symbols land on reels 1 and 3 only, carrying prize values from 1x up to 3,000x. But those coins don't pay by themselves. You need a Collect symbol (the piggy bank) to appear on reel 2 to scoop up whatever coin values are sitting on the outer reels. If two Collect symbols show up at once, the values get collected twice. During Hold and Win, every new Collect symbol resets your respins back to three, so the round keeps going as long as collectors keep landing. Mini, Minor, Major, and Grand jackpot coins can also drop in during respins - Grand sitting at 3,000x.

There's also a Piggy Bank trigger in the base game where a single Bonus coin plus a single Collect symbol can randomly upgrade into a full Hold and Win activation, with extra symbols added to the grid. It's a nice safety net for triggering the feature naturally. The downside of the 3x3 format is obvious though - five paylines means the base game is thin. Regular wins top out at 10x for three Wilds, and the card symbols barely register. Almost everything rides on getting into Hold and Win and landing high-value coins alongside enough collectors to keep the respins alive.
