'Tis the season ... to play webgames!
Grow Ornament—I love Grow games and I love tree decorating, making Grow Ornament a double-awesome webgame. It's Grow, so you know what to do.
Snowman Salvage—Build snowmen and keep them safe from harm. (Watch out for aliens, they really like snowmen.)
Winter Tales—This is a classic construct-a-path type game featuring a snowman on a sled. Yea! Snow!
