Features that tie the series together
| Feature | Description |
|---|---|
| Fight → sticky wild | In free spins, when a Viking symbol wins a fight against an enemy, it becomes a sticky wild until the free spins end. This has been the core of the series since the first game. |
| Rage meter | Each Viking has their own meter. Winning with that Viking in the base game fills the meter, and when it’s full, free spins start with that Viking in Berzerk state (from Berzerk onward). |
| Berzerk | A Viking in Berzerk state always wins the fight. |
| Ragnarok | A special free spins round where all four Vikings go Berzerk. |
| Treasure chest | Appears on the last reel and gives rewards such as free spins, coin wins, and extra wilds. |
What each game added
- To Hell (2018): Fights can also start in the base game with 2 scatters, and the free spins are split into two stages. Beating the final boss triples the wins from both rounds.
- Berzerk Reloaded (2021): A remake of the 2016 game. Wilds carry multipliers up to 8x, and it added bonus buy and a free spins gamble.
- To Valhalla (2022): Filling the rage meter grants up to 20 respins, during which one Viking always wins the fight against Jormungandr.
- Wild Fight games (2024~): The setting moves to Egypt, Olympus, Las Vegas, and Hollywood. Olympus and Hollywood add RushingWilds, where the wild multiplier rises each time a fight is won.
The 4 Fantastic Vikings games, which studio 4ThePlayer released through Yggdrasil, are a crossover of Vikings Go Berzerk and 4 Fantastic Fish and share the Viking characters.
