How many patterns can you complete? Players must use the top row of shapes to complete the pattern below it. To select the correct gem, simply navigate with the arrow keys. Press the down arrow to shoot the appropriate shape into position. Take too long, or get one wrong, and white squares will stack up along the sides. If the white squares stack up to the top the game is over. Compete to have the highest score on the "Easy," "Medium," or "Pro" leaderboard.
