Fun office holiday party games include funny employee awards, Secret Santa, work bingo and a trivia competition. Any office game should begin with an icebreaker, so that even reluctant coworkers are encouraged to play along.
For funny employee awards, present certificates at a mini ceremony that recognize employees for silly things like who makes the coffee every morning or who always uses up all the printer paper. For work bingo, make bingo cards with each square containing statements such as "I have lived in a foreign country" or "I speak a second language." Each player has to find a co-worker who matches each statement until the player has checked off an entire row of squares.
