How to play

The snakes rise from the holes, one at a time. Watch the order and tap the holes in the same sequence (on the keyboard: 1 to 4). Each round the sequence grows. Reach round seven. One mistake and the snake bites.

The story behind it

In the sagas, Ragnar Lodbrok dies in the snake pit of King Ælla of Northumbria, singing. It is a legend, not a confirmed historical record. The memory game is made up. Read the story in Ragnar Lodbrok and the snake pit: the hero of the sagas and what the chronicles kept of him.
