Top/backspin

Sidespin

+ topspin dips the ball, - backspin floats it. + sidespin (counter-clockwise from above) curves it to the left. Drag on the table to aim. Space = launch.

Paddle (return stroke)

Paddle returns the ball (perfect timing)

Swing speed

Brush angle

Face tilt

Face yaw

Brush angle: 0 = flat drive, + brushes up (topspin), - brushes down (backspin). Tilt: - closed face, + open face.
