Swap

Can you solve the puzzle which dates back to the Victorian era? Your goal in this game is to exchange the positions of the two sets of arrow tiles with as few moves as possible. You will be given two rhombi with an empty space between them, and 8 red arrow tiles are placed inside the rhombus on the left, while 8 blue tiles are located on the right. You can move the tiles by clicking them. A tile can be moved to the empty space if the tile is adjacent to the space, or when another tile is located between the moving tile and the empty space. The number of moves you have made will be counted at the top of the screen. Try your best to limit the number of steps or you may receive no points even the task is completed!
