Another way to score without a computer system, which works well in any pool hall, is using the diamonds on the table. Each diamond is worth 3 points. If you just pocket the purple on your visit. Move a penny, nickle or dime to the middle of the two diamonds. That indicates to you and the other player you are now shooting orange. When you pocket the black ball or miss the black ball you move the penny up to the correct diamond. Viola! Your marking score. If your playing to 21, it ends at the end of the table! Real simple. Easy to glace over to see which color your opponent is shooting next. Very important.
