Inferno Riches Slot by HeronByte

Five reels of circular demon coins spinning over a volcanic hellscape - reds and blacks everywhere, lava pools below, jagged mountain silhouettes against a burning sky. Each symbol is a stylized creature face: purple, pink, gold, green, blue, and teal, all rendered as ornate medallions. The higher-paying creatures have more detailed designs with glowing eyes and sharper features.

The expanding wild is the centerpiece. When it lands on any reel, it stretches to fill all four rows. On a 40-payline layout, one fully expanded wild reel connects to paying combinations across a significant chunk of those lines simultaneously. Two expanding wilds on separate reels during the same spin is where the real damage happens, though that combination doesn't show up often at 12% hit frequency.

Double Chance doubles your bet size to increase the odds of triggering the free spins bonus. Payouts still calculate from the original stake, not the doubled amount - so you're paying extra purely for access to the feature, not for bigger line wins. The buy bonus option skips the wait entirely and drops you straight into free spins for a fixed price.

There's also a gamble feature after any win, capped at four consecutive rounds. It's a coin-flip style risk where you can double up or lose everything, with a maximum wager limit of 125,000 credits. Simple, but it gives the game a bit of extra dark-themed tension when you're sitting on a decent expanding wild payout and deciding whether to push it.
