- A SpinOn slot with 10 paylines that pay both ways

- A Bonus Wheel round with picks worth up to 100x and a max win of 4,966.4x
Aurora Storm is a SpinOn slot released through Yggdrasil on 8 October 2026. It sends the reels into space, where the Northern Lights, also called the aurora, unlock the mysteries of the sky. Yggdrasil’s tagline for it is “Brace yourself for the cosmic chaos!”
SpinOn gives the max win as 4,966.4x the bet. The game is built on two features: expanding Wilds that set off Sticky Respins with multipliers, and a Bonus Wheel round that Yggdrasil calls the eye of the storm.
Paylines That Pay Both Ways
Aurora Storm has 10 paylines, and they pay both ways. A win can be made from left to right, as in most slots, or from right to left. With only 10 lines, paying both ways means each line can win in two directions.
Expanding Wilds
The Wild is the symbol to watch in the base game. When a Wild lands, it expands by a random number of positions. It can grow sideways, up and down, or both. A single Wild can therefore stretch along its row, up and down its reel, or both, depending on how far it spreads.
Once a Wild has expanded, you get a respin. The expanded Wilds are locked in place as sticky symbols while the rest of the reels spin again. With the expanded Wilds held still, the respin gets a head start, and the lines can still win in both directions.
Sticky Respins and Global Multipliers
SpinOn calls these Sticky Respins, and they come with a further boost. According to SpinOn, the respins bring Global Multipliers of up to x50.
Put together, this is the main way the base game can pay well. The Wild expands, the expanded Wilds stick for the respin, and a Global multiplier can then lift the result. SpinOn describes them as fresh Global Multipliers.
RECOMMENDED CASINOS TO PLAY Aurora Storm
Bonus Wheel
The bonus round is triggered by landing Scatter symbols on all three middle reels. That takes you into the Aurora Storm Bonus, built around a Bonus Wheel.
SpinOn says the wheel lets you level up and stack multipliers as you go, with rewards of up to 100x per pick. In its words, the wheel only stops when the storm says so.
Stakes, RTP and Max Win
Yggdrasil lists a minimum bet of €0.10 and a maximum bet of €100, with a default bet of €1. It gives the max win as €496,600, which matches SpinOn’s 4,966.4x figure on the top bet.
The game comes in four RTP versions: 96%, 94%, 92% and 90.5%. Which one you get depends on the casino, so check the game’s information screen before you play. RTP is worked out over a very large number of spins and does not tell you what will happen in a short session.

Overall
Aurora Storm is an easy slot to pick up. There are only 10 lines, but they pay both ways, and the base game is built around one clear event: a Wild landing, spreading out and sticking in place for a respin.
What lifts it above a simple expanding Wild game is the Global Multiplier of up to x50 on those Sticky Respins, and a Bonus Wheel round where you can level up and stack multipliers, with picks worth up to 100x.
With a 4,966.4x max win and a choice of RTP versions, Aurora Storm suits players who like simple, readable features in a space setting.
