Rainbow Cube

Rainbow Cubes are a form of currency in Cookie Run: OvenBreak. They are usually very rare and are hard to collect vast amounts of, but there is a recipe for 200 Rainbow Cubes in the Magic Laboratory, which takes 3 days to use again. They are used to buy Costumes, which give extra bonuses to the player.

Earning Rainbow Cubes
Rainbow Cubes are very rare, and the only quick way to collect them is by the Magic Laboratory. They are only used to buy Costumes.

During an event, however, there is usually a new item that you can create that will give the player more chances to obtain Rainbow Cubes.
