Some good tween games.... Would-you-rather is always a good one for your younger tweens. (8-10) though it will not occupy for long. Truth-or-Dare has always been a classic (11-13). I suggest this game for girls. If your worried about inappropriate questions you can order/make a deck of cards that has pre-made truth-or-dare ideas on them. If your looking for a longer lasting game your going to want to have some type of sport. Or, possibly for girls, a 'spa'.
Game: Would-you-rather Ages suggested: (7-10) Lasts: Short period of time, 10-30 minutes.
Game: Truth-or-Dare Ages suggested: 11-13 Lasts: Medium period of time, 25-60 minutes.
Game: Sport/Spa Ages suggested: Any age Lasts: Long period of time, 45-180 minutes.
