If the Millionare event is temporary, whats the point of shoving diamonds into it? Diamonds are already required for a lot of things and you need a LOT for them.
It will be for around 1,5-2months. Em..these diamonds can be returned well if u invest into event :) But ye, u will lose all spent diamonds after event, but like i said rewards are great.
This game becomes really easy when you figure out that farming any of the 10th level stages gets you a LOT of money and is really easy to farm as well.
