Supply Drops are points of interest that are visible on the map.
They will drop a small amount of Items for players when spun by either tapping or swiping them on the screen. The items given can vary but will usually consist of a small amount of darts, a small amount of coins or, rarely, a small amount of cash.
There is usually a cooldown time of 15 minutes after spinning a Supply Drop, however, there will sometimes be a watchable advert that will allow for a second immediate spin.
During events, special green Supply Drops will appear. So far, it appears that during events, specific event creatures will continuously spawn at these Supply Drops for a limited amount of time.
