A brand new update arrived in the SimCity Social online Facebook game in the form of Delivery Trucks which has caused much confusion in the SimCity Social Universe. Here is going to try and explain everything that there is to know regarding Delivery Trucks and how you can make the most of them.

There are four different varieties of Delivery Trucks including Bronze, Silver, Gold and Platinum, each of which offer different rewards that increase as the value of truck increases from Bronze to Platinum.

These Delivery Trucks will drive around your SimCity throughout the day, but once one of them is unlocked you will not receive another one until the following day. Gambling on which Delivery Truck to unlock is an exciting element to the update.

In order to unlock a Delivery Truck you will require keys that match the colour of the Truck. So Bronze keys will unlock Bronze Trucks, Silver Keys for Silver Trucks etc.

You can obtain Bronze and Silver Keys by requesting them from friends and Neighbours. This option is available by clicking on that particular Delivery Truck and clicking on the 'Ask' button or alternatively if you have some of those coloured Keys in your Inventory then simply ask your friends for more. Gold and Platinum Keys require Diamonds in order to purchase them and cannot be requested.

You can hold a maximum of 9999 Keys in your Inventory of each colour so simply keep requesting them to create a stockpile in your Inventory.
