Hula Hoop Pass

A game where all participants stand in a single line holding hands and pass a hula hoop from one end to the other.
Because you must keep holding hands and move the hula hoop over your body, the smaller the hoop and the more participants there are, the more difficult it becomes.
You can also enjoy a different kind of challenge by using items like sashes or ropes instead of a hula hoop, so trying variations can be fun.
It’s a guaranteed crowd-pleaser indoors or outdoors, and a great sports day event that people of all ages can enjoy.
flysheet relay
The “fly sheet relay” is where four people carry a square sheet with a ball on top, working together to transport it.
It sounds easy, but it’s actually quite tricky: if you don’t keep the four corners of the sheet at the same height while running, the ball will fall off.
When kids are participating, try using a larger sheet; if it’s only adults, use a smaller one—adjust the difficulty based on the participants.
If you want to make it even more fun, set up obstacles on the course to ramp up the excitement—highly recommended!
Bubble Ball Sumo

Bubble Ball Sumo adapts the rules of traditional sumo while players wear bubble balls on their upper bodies and body-check each other.
Beyond its funny appearance, it becomes a deceptively deep contest thanks to the strategy of how far to push and when to dodge.
It can be run safely even in limited indoor spaces, and laying down mats on the floor makes it even safer and more enjoyable.
Momentum and timing often decide the outcome, leading to surprising upsets that are a major highlight.
Organizing head-to-head matches in a tournament format amps up the cheering and can strengthen class unity.
Win or lose, everyone ends up smiling—this is a hard-hitting performance that can be the centerpiece of any event.
Ball pool treasure hunt

Ball pits are hugely popular with children, especially little ones.
Even adults watching from the sidelines might feel tempted to jump in because it looks so fun! Let’s try an indoor game using a ball pit: a treasure hunt in the ball pit! There are surely places like preschools where kids regularly play in ball pits, or facilities that have a ball pit but aren’t making the most of it.
Try mixing in items that are a similar size or color to the colorful balls—things that are a bit harder to spot.
Even children who get a little nervous at events like sports days might enjoy this as a playful, low-pressure activity.
Fruits Basket

Fruit Basket is a game that almost everyone likely experienced as a recreational activity in childhood.
You prepare a number of chairs that is one fewer than the number of participants, and the “it” stands in the middle.
The basic rules are: participants are divided into groups by fruit in advance, and when the “it” calls out a fruit, the people assigned to that fruit must get up and find a different chair from the one they were sitting in.
At the same time, the “it” also searches for a chair, so the person left without a seat becomes the next “it.” There are also local rules, such as everyone having to stand when the “it” calls “Fruit Basket,” or not being allowed to sit in the chair immediately next to you.
Thanks to these, the role of “it” doesn’t get too lopsided, making it a fun game for everyone.
