Younger children will learn to add, interleave and remove objects while adults will exercise their mental ability trying to solve the puzzle. To start the goal you must choose what type of board you want to play, because each has a different complexity depending on the number of blocked records at the beginning of the play and they'll unlock with the release you get done. You should know that a box will be blocked if it has another on the left, right or above, but don't panic if there is a below or above. To eliminate the pieces you have to do it always in pairs, that is to say, select two identical looking that are not immobilized and pop them. You can rule out different types of formats: from flowers and plants to seasons, numbers and many more.
Don't be afraid because you will have no limit time to solve the board, so concentrate and meditate about the movements that you want to make. There are countless of levels at your disposal, once you overcome one the difficulty of the level will increase, Luck!
