Games and activities for a ninja birthday party

Need some inspiration for ninja-themed birthday party games for your little one’s big day? Take a look at these ninja party games to wow your guests.

  • Blind Ninja (adaptation of Blind Man’s Buff): In this game, one guest is chosen to be the ‘Blind Ninja’. This person is blindfolded and spun around a couple of times. The other guests all choose a place to hide, while the Blind Ninja counts to ten. The Blind Ninja has to find and ‘tag’ all of the hidden players to win the game.
  • Balloon Ninjas: Tie some balloons on different lengths of string, and place them in the middle of the room (or outside!). Each guest can take their turn kicking the balloons, with each height of the balloon scoring a different number of points. The guest with the highest number of points at the end of the game wins!
