Winter sports or winter activities are competitive sports or non-competitive recreational activities which are played on snow or ice. Most are variations of skiing, ice skating and sledding. Traditionally, such games were only played in cold areas during winter, but artificial snow and artificial ice allow more flexibility. Artificial ice can be used to provide ice rinks for ice skating, ice hockey, and bandy in a milder climate.
Common individual sports include cross-country skiing, alpine skiing, snowboarding, ski jumping, speed skating, figure skating, luge, skeleton, bobsleigh, ski orienteering and snowmobiling. Common team sports include ice hockey, curling, and bandy. Based on the number of participants, ice hockey is by far the world's most popular winter sport, followed by bandy. Winter sports have their own multi-sport events, such as the Winter Olympic Games and the Winter Universiade.
