Wrench Rally. Race four cars around one screen. Steer with the left and right arrow keys or A and D; hold the up arrow, W or space for the throttle; the down arrow or S brakes and reverses. Lifting off the throttle is the main way to slow down for a corner. On a touch screen, steer with the bottom-left and bottom-right zones and brake with the pad above the right-hand zone. A gamepad works too: left stick or d-pad to steer, right trigger or A for the throttle, left trigger or B to brake.
