At the start of the game 25 cards will be dealt into 5 x 5 grid. Each time you need to pick up a pair of cards to remove them. A card can be paired with another card of the same number which is adjacent horizontally, vertically or diagonally. When you have done removing pairs, click the stock pile and the cards will move to fill in the gaps. The rule of moving of the cards is basically that the card on the right of a gap will move to fill in the gap, if the gap is on the last card in a row, then the first card on the next row will move to fill the gap. After the move cards will be dealt from the stock cards to fill in the remaining gaps, and then you can match the cards again. You need to plan and calculate how the cards will move when making your matches in order to make as many matches as possible. The game ends when no more matches can be made. The more cards matched, the higher your score.
