Although these games are the "best we know", it has 46 new and unpublished activites.
The book contains 10 Warmups, 17 Openers, 18 Socializers, 14 Fillers, 13 Energizers, and 27 Closures. It makes a perfect complement to the book called "101 of the best Corporate Team-Building Activities we know!" since there are no overlapping activites and the "101" book is focused on problem-solving activites.
