My brilliant friends have, perhaps, invented the first, the second, and the only existential ball games in the entirety of this little island-nation Taiwan.
The games--as follows:

The first goes by the name of Insanity Ball.
The rule goes: "You must have a ball."
This ball, then, represents life.
With the ball, one can do absolutely anything, but when the ball is gone, the game is over.

The second, invented just yesterday, is Ball Ball.
Ball Ball is a variation of baseball, played on the school plaza with two teams of two.
Among the rules is this: "You can use anything but a ball." The absent meaning in any individual's life, then, is replaced by whatever they choose to be meaningful.
The players then continue the game as a baseball game would continue, but among the rules: "At the end of the game, the two teams of two players choose a separate side of the coin and flip it. The team who guessed correctly wins the game." The game, alas, shall end with the hand of chance choosing the winner and loser, and all previous efforts at meaning ultimately are reduced to naught. But the game itself, as you played, it had meaning.
