Enable before you press Play — locked in for that run.
Pull down and away like a slingshot, release to fire. You gain +1 ball every round — chip every block to zero, and hit gold power stars for an instant ability, live in the middle of your shot. Find a Revive and you'll survive a topped-out board — it carries into your next run too.
Race a friend on identical boards. Whoever survives more turns wins.
