These items provide the player with the ability to reduce the remaining coins / supplies production times of all buildings. The bonus does not apply to special productions or Great Buildings, but if you have a supply production active in your Special Buildings, it will work on it.
Each of these items exists in three sizes (small, medium and large). This is represented with a bronze, silver and golden clock rims, as well as with the brightness of the glow around them. The Bronze and Silver rush reduce all buildings in the town by a specific amount; the Gold Supply rush will instantly finish the supply production of a single building that is not a Special Building nor a Great Building.
