 The “X” was referred to by the Russians as "sakko", a name confirming that these Russians had indeed learnt the game from the Sámi, or alternately that they themselves were Russian Sámi.Sáhkku was considered a sinful game by Christian missionaries and Laestadian evangelists.As a result of this religious pressure - in addition to official Norwegianization policy’s pressure to abandon all aspects of Sámi culture and identity, and the destruction of Coast Sámi material culture during World War II - sáhkku began to fall out of use in Sámi communities after the 1950s.
