This is a great game that is easy to learn, but hard to master! It is similar to a game of Jacks, with the addition of a ball to bounce between moves. Each set comes with 5 biji bekel and a bouncy ball.
It has long term playability, once you’ve mastered the bounce and collect aspect, you can then return the biji bekel to the table, turn them, collect two at a time…
