The kids are allowed to look through the deck and choose whatever cards they want. I go over the rules using the slides above, but I offer no suggestion on strategy because I want to see what they do. The groups that put some forethought into it and use a strategy are inevitably more successful. Kids that go one card at a time will usually end up with one empty spot where no card will fit. This will then send them backwards to try to adjust.
