I've kept some of the older Flash versions of games for playing on PC desktops (still my favorite electronic device :) ).
Design and "Cut" a snowflake: Draw the cuts on the folded "paper" and see the snowflake design.
Bell Playing Polar Bears: Make music by moving your mouse over the polar bears.
Ice Cubes Game: Help the penguin catch the ice cubes.
Snowball Fight!: Aim at the boys and throw the snowballs.
Winter Maze: Online maze with a winter theme
