One player selects a shot by clicking one or more of the buttons that describe the different types of shots possible, such as regular shot, off the wall, swish, off the back board, etc.
To attempt a shot: (1) move the ball with the mouse to position it, (2) click-drag the ball to select the direction and power of the shot, (3) release the mouse button.
If the shot is successful precisely as selected, a challenge is made to the other player to duplicate the exact same shot. To help with this, the ball is automatically positioned in the exact same spot for you. If the challenge shot is made correctly, no points are scored. If the challenge shot fails, a point is scored to the challenger (the one that successfully made the shot).
Play continues until one person scores 3 points and wins the game.
Analysis: This game is a lot of fun and I found myself wanting to play over and over again. The physics are realistic enough for a game of this type and there are enough different shot combinations to keep the game play interesting. The mechanic is a simple one and won't take long to become familiar with how to do it. Perfecting shots, however, is another matter entirely and that's what makes this game so much fun. Kudos to the folks at Gamesheep for coming up with another great one-on-one Web game.
One word of advice: If you are the one being challenged, be sure to look in the upper right portion of the game window to see the type of shot you need to make. Also, watch the angle and power with which your opponent shoots the ball if he/she goes first, as you may have to repeat the same shot soon after.
