All you have to do is toss the ball (orb) off your edge using less than 50 pieces, no attaching stuff to the orb, your contraptions must touch the orb. Edit: new rule, if the opponent uses too many pieces then you get too delete whatever pieces you want from their contraption to make it follow the limit, Example: It has 58 pieces, you get to delete 8.

ahhh... right side wins
Keep it going now and have fun!
