Pip counting is a very important skill in backgammon and practicing helps you to do it quicker over the board. One way to do this is to keep a running count of the pip difference. You can use this to practice counting the difference.
This simulates the dice roll. +3 4 counts as 7 and -3 3 counts as -12. Sometimes a hit is shown like +8*. Press Total to see the running total and to start again just reload the page [F5].
