Lucky Run is an offer in which you unlock the rewards while playing the field. Some stages are special bundles that you can buy. These bundles include in-game items and Kredits, so you get double the benefit.
Wait for the offer to start and for the information about in to appear in the "News" section of the website.
Go to the offer page and make sure that it is active.
Open the game fields. There are three types: free, special offers and locked. The first two are available from the start and do not require additional actions. Special offers are activated by purchasing a bundle from the field. Locked fields become available after you purchase the bundle that precedes those stages.
