Core Part: Spin
Spin originally appeared in Core Random Booster Vol. 1 as the "Rare" Core. It features a body like that of Break core, and two Hold Parts, with spear-like tips of differing design and size. It also features a Trigger like that of certain other Cores. Horizontally mounted on the Hold Part with the larger tip is a rubber strip, similar to Accele. The Core's gimmick, which leads to its name, is that when a B-Dama is fired from it, the rubber strip gives it a sideways spin. When the marble hits a wall while it spins, it rebounds at an angle. The direction of the spin can be changed by taking apart the Core, flipping the Hold Parts, and then putting it back together in that form
