-----THE FIRST MOVE YOU MUST HIT THE OPPOSITE ARROW TO START THE CORRECT TIMER----- Click the "right arrow" key to start the black timer, and stop the white timer. Click the "left arrow" key to start the white timer and stop the black timer
If you hit the arrow keys too fast the timer stopping mechanism will break. (you have to hit the arrow keys VERY fast for that to happen tough.) so don't hit the arrow keys too fast. (it might change depending on the computer.)
