How to play

The wall grows on its own every second. Tap the hearts that appear on the screen to distract the horse Svaðilfari: each heart stops the work for a few seconds. Hold out for 60 days, the game’s seconds, until summer arrives with the wall unfinished. If it reaches 100%, the gods lose Freyja, the Sun and the Moon.

The story behind it

In Snorri Sturluson’s Prose Edda, the builder had one winter to finish the fortress, and Loki, disguised as a mare, lured his horse away. The game simplifies the account. Read the story in How Loki tricked the builder of Asgard’s wall and gave birth to the horse Sleipnir.
