If your house is anything like mine, your kids have accumulated a ridiculous number of boxed games - lotto games, memory games, card games, you name it. And if you have a destructo-baby like my younger daughter was (who am I kidding, is), then some of those big bulky boxes might not be in exactly pristine condition.
My tip is ziploc bags. Put each game in its own bag and throw out those bulky boxes. The games will take up a fraction of the space, the kids can easily see what's inside, and cleanup is a snap.
Works for me :).
