After you complete a brief tutorial you can begin constructing various item producing structures to power your base. These buildings then need to be leveled up by completing tasks which will involve waiting for timers to complete. Boosts, which are either won during the game or purchased using real money can be used to reduce the time you need to wait for the timers to complete. Boosts come with different reduction times, the shortest being five minutes. Note: Build times become longer as you increase your levels so try to avoid the temptation of using boosts straight away and save them for when you really need them.
