Start a race against the Viking hordes with building a high and stable tower! You need to arrange the blocks in numerical progression from low on top to highest at the bottom.
Each turn you either take the numbered block that's presented to you and use it to replace one in your tower, or chance it by taking the mystery block. You can score bonus points by placing sequentially numbered blocks adjacent to one another and when finishing the level extra points based on how high the number is at the top of your tower. Finish your tower before the others do and avoid that the mighty Viking Axe destroys your own tower.
Besides fighting the Vikings, be double challenged by getting that #1 position in the high score list!
