Play Time Reward (CoS)  

City of Steam Wikibase™ Guides

Each day City of Steam rewards your time spent in game by tossing you a few health and steam potions, and some vehicle parts. These gifts may be claimed after the times listed below. However, there is a catch. The countdown clock to the next reward does not start until you claim the one you have already earned!
