As you play Rush & Cash, at the start of some hands, selected at random, chips will drop on to the table. That is called Cash Drops.
Cash Drop amounts will vary (from 10 BBs to 600 BBs); smaller amounts will go into the pot inducing more action, while larger amounts will be divided equally and added to every player's stack right away as a straight-up reward.
