    How to Play

    • Within the game, choose any two windows.
    • If the images under the selected windows are equivalent, a match is made.
    • In one-player mode, the game ends when all six matches are made. In two-player mode, points are earned for matches, and the player with the most points wins.
    • Wins will translate into socks, which will hang in between the buildings.
