It is all about perfect timing and strategizing skills at the same time. Stick a given number of pins in a revolving orb and make sure that the heads of the pins don't get in contact with the other pins’ heads. The orb has a ring whose distance varies constantly!. The distance of the ring around the Orb will determine how far your pins will stick out of the Orb. This means you can place several pins in the same place. Play BU and showcase your precision and focus in 75 fantastic levels.
