We stack sports balls and as soon as two identical balls touch each other

The golf ball becomes a ping pong ball, the ping pong ball becomes a billiard ball etc., the ultimate ball being the fitness ball.

If you ever manage to merge two fitness balls, they disappear and give you a nice jackpot of points!

Yes, the game doesn't stop there, the goal is to get the best possible score. The bigger the balls you merge, the more points you earn. But watch out for game over. Indeed, if a ball ever goes beyond the edge of the playing field, the game is over!

Where the game stands out is in its physics. The balls of each sport are not fixed. They can roll or bounce and each ball has a different weight. It is this element that gives the game its charm and also makes it addictive.
