Smashsticks-on-Ice

Smashstick-on-ice is a winter game played by Vikings.

Game Info
(Taken from the book How to Cheat a dragon's curse)  It was a very rough and complicated game played with bats, balls and Ice Skates. Nobody was quite sure of the rules, which meant people tend to make them up as they go along. and then anybody who complained would start a fight.

The Young Heroes (Ex: Hiccp) were suppose to go first, followed later on by the Adult Warriors (Example Stoick.)

Note
With the pic depicting Camicazi and Fishlegs on pages 72 and 74, one could argue that Smashsticks-on-Ice is a preform version of Hockey.
