How to play

See which letter has the seal, follow it while the three change places and tap it (or use keys 1, 2 and 3). Get six right; the third mistake ends the game.

The story behind it

In Saxo, Amleth changes the message that would have killed him, and the bearers die instead. The letter swapping in the game is made up. Read the story in Amleth: the Danish prince who feigned madness and whom Shakespeare turned into Hamlet.
