How to play

A marker moves back and forth over the bar. Tap (or press the space bar) when it passes through the golden zone for a clean stroke; the rhythm speeds up little by little. Strokes outside the zone count as errors, and five errors sink the crossing. Make twenty strokes in 45 seconds.

The story behind it

On 8 June 793, Vikings attacked the monastery of Lindisfarne, in Northumbria, and the date became the marker of the start of the Viking Age. The details of the crossing and the rowing rhythm are made up for the game. Read the story in Lindisfarne, 793: the attack on the monastery that Europe remembers as the start of the Viking Age.
