In every purchase you make in the game, your account is automatically converted to an "Exclusive no-ads" one, hence, you will no longer see the ads between levels as well as the banners at the bottom of each level.
However, this does not influence our suggestions to our new in-house games we think you may like (which can be dismissed upon opening by hitting the "X" mark), nor the reward videos we offer, to gain additional coins and/or extra moves.
Should you require additional information regarding the matter, please let us know by writing to us.
