Box & Car Rally.
Affix christmas paper tubes or paper towel tubes into an empty cardboard box, add Rally cars and Viola! A Plinko-Style car game to keep the kids interested and out of your hair.
All you'll need is some masking tape, a hallway and your imagination. Create an obstacle course like the one pictured here and see who can get through to the other side to reach the "treasure". Easy to do, easy to clean up and the course can be changed again and again... so long as you don't run out of tape.
