At some family reunions, really competitive games sometimes create big laughs. A jigsaw puzzle race may seem like a low-key game, but it doesn't take long to bring out the spirit of competition at large family events -- so much so that you may want to avoid this one if you know there are sore losers in attendance.
Divide everyone into teams with equal numbers of players, and give each team a jigsaw puzzle. The puzzles can be identical, or they can be similar, with about the same number of pieces and level of difficulty. Of course, if your teams are made of different age groups, be sure to give children easier puzzles.
Start a timer, and give everyone a set amount of time to complete the puzzle. The team that finishes their puzzle first wins. If no one finishes in the predetermined time, the team with the most complete puzzle wins. Prepare a prize table with inexpensive gifts and let the winners choose their rewards.
Don't forget the timer, especially if you selected devilishly difficult puzzles for the game. Otherwise, your reunion might last hours longer than you anticipated.
