Photo Memory Game 
Required:
close-up photos of items or scenes around the meeting place.
Preparation:
Take photos of objects around the location where your troop meets - the front door, a lightpost, the clock, the rug, a mailbox, a big rock, ...
Make a slideshow of these photos, OR if you use a digital camera, and have a laptop and projector, you can project on a wall.
Instructions:
Dim the lights and show the first photo. If a scout believes he can identify the object, he raises his hand or stands up. The leader calls on him to identify it.
If correct, his patrol gets 2 points.
If incorrect, his patrol loses 1 point.
If a scout shouts out the answer before being called on, no penalty but no points awarded and the scout that is called on just gets a free clue thanks to the out-of-turn scout.
Patrol with the most points accumulated wins.
You could use photos from a recent event, or at the end of the year use photos from throughout the year. That can be a fun recap of the year.
