Spellbinding Games

Keep the magic going with these witch-themed games!

  • Broomstick Racing: Kids race on broomsticks around a set course. Whoever zooms across first wins, but watch out for magical obstacles!
  • Musical Brooms: Pass a broomstick around the circle until the music stops — whoever holds it is out!
