All of them have samba as their setting … yes, Brazilian music. So the appearance of the new levels is striking and fun, something that is already common in these games. By the way, to be able to play them is necessary to have several finishes of the previous levels, at least, with two-star ratings, so if you deleted this title at the time … bad luck, you must start from scratch.
Therefore, the novelties are considered as “bonuses”, and there is an internal subdivision in them: the first 18 are those that have to be played and get the necessary stars to be able to access the remaining six. That is, you have to have a minimum of skill at the time of finishing each of the new challenges … of course, with the new levels some new aids are included that are really useful (such as a slingshot that goes much further).
A matter of foresight …
By the way, an optimization of the store within the app itself in this new installment of the game … since the purchase of the improvements, if they are spent, is done with great simplicity and in a much more optimal way. A nice touch from Rovio, who insists on this way of generating income.
