The Best Penguin King Casinos and Slots in 2026

Break the Piggy Bank is Penguin King’s flagship slot and the most recognizable game by the developer. It’s a vibrant video slot with bold graphics, a money theme, and five different jackpots. There are only 5 ways to win, so it’s a simple game.

Golden Coin symbols can land in the base game to deliver instant coin prizes. It gets more rewarding in the Hold and Win bonus, since the game mascot appears as a Collector symbol to accumulate all the coin values and add them to your bonus win. Depending on the build, you can land multiple collectors with multipliers attached to them.

Golden Coin symbols landing during the round can break open piggy bank symbols and award any of 5 fixed jackpots. The number of piggy banks that break during the round determines which prize you get. The game has a 95.72% RTP and a 4,500x max win. Volatility is around medium level.

Serpent Gold is a snake-themed slot, but what the game really focuses on is Gold Coin symbol clusters. Anytime adjacent coin symbols land, they stick to the reels and trigger 3 respins that reset if new symbols join the cluster.

Serpent Gold is a 3 pot-style game, so you’ll find three snake symbols that can trigger different modifiers tied to Gold Coin clusters during the Hold and Win bonus: Collect snake collects all prizes in the cluster, Clone snake clones the cluster symbols, and Double snake doubles the coin prizes. The slot transforms to a 6×6 grid during the bonus game, and five jackpots can also be won.

The animation on this slot feels even more high-end than the rest of the catalog. As such, it’s one of their most stunning releases. It’s also one of the more volatile slots by the developer, but not so much that it’s intimidating. You can win up to 6,001x your entry, and the RTP is 95.78%.

Thunderline Express is a classic slot because of the 3×3 setup, 5 lines, and traditional slot symbols like bells, horseshoes, and lucky 7s. But the graphics and animations are the stuff of modern video slots. The Thunderline Express train crackles with electricity at the top of the grid while coin and jackpot symbols shoot up into the coin pile and jackpot vaults with flashy effects.

Lots of special symbols to help you grab instant prizes can land in this slot, including Coin Train Collector and Jackpot Train Collector. The game features go into turbo mode in the Hold & Win bonus, and there are four jackpot prizes to be won, with a modest max potential of 2,250x your entry.

Bold and vibrant graphics contrast with classic nostalgia in this 5×3 slot. If you like old-school fruit machines, this one gives the same vibe but with a few modern extras. Besides the great visuals, the slot features Wilds, Scatters, and up to 40 free spins in the bonus round. The highlight of the game is the symbol transformations, where single 7s can transform into 77s or 777s.

The paytable is displayed in a grid above the reels, so that the game looks like it has double reels. There are three jackpots too – Mini, Minor, and Major. The RTP of 95.74% is standard, and there’s a generous max win potential of 8,000x.

This is one of the many spin-offs that have been inspired by the Break the Piggy Bank slot. It’s a Halloween-inspired take on the game, but between the vibrant colors, quirky symbols, and the charming Count Pigula, the slot is far from scary. Instead, this 5-reeler is rich with playful excitement. Piggy banks have become pumpkin banks, gold coin scales now hold candy treats instead, and the Collector is now a Count Pigula.

Five pumpkin banks floating atop the reels correspond to five jackpots. Instant coin prizes and a Hold and Win game hold all the action. If you like Break the Piggy Bank, this one manages to be similar but also unique. The game has a 95.72% RTP with a 4,512x max win.
