To sell items, create items, research recipes, improve your store or use your thug in the game you need to have at least one gameday point.

You gain 1 point every 15 minutes, up to the amount of 5. In addition you can buy extra days with Edgebee tokens.

When you are out of day points a screen will show up telling you how long you have to wait before you will have regenerated a gameday point.
