ChessboardCards is one of the multitude of Patience (or Solitaire) type card games.
You have to convert the initial pattern into a chess board arrangement of alternating red and black cards.
A move consists of moving a card to the bottom or right of the grid by touching the card.
This will cause the other cards to move left or up to fill the empty space.
You can play so that only columns are considered (i.e. the card is always moved to the bottom of the column when selected) or with both columns and rows. Use the Settings Menu item to select the mode you want.
When playing in columns and rows mode the cards are moved on alternate moves to the bottom or to the right. This is the more difficult version.
