Fun games for 9-year-olds include card games, puzzles, freeze tag, scavenger hunts and indoor bowling, according to Today's Parent. For a scavenger hunt, create clues to help the children find the objects. Hide enough objects for each child to collect an item and earn a reward at the end.
Set up an indoor bowling game with water bottles, duct tape and a medium-sized rubber ball. Line the water bottles up in proper formation and create a start line with the duct tape. Make it extra fun by keeping score and handing out trophies at the end of the game.
Turn the living room into an entertainment center by setting up a variety of stations with different games at each table. Set up a card table for games such as Uno, go fish, rummy or blackjack. Add Monopoly, Life or Scrabble to a table. At another table, create a touch-and-feel box that children reach in and guess what objects are inside. Offer raffle tickets that the kids can trade in for small prizes.
Put a twist on freeze tag by tuning the game to music. Turn on the radio and have the kids dance until the music stops. Children who are still moving when the music stops are out of the game.
