If you pot five ball in a row it moves you up a multiplier. It starts at 1. Then after potting five your score multiplies by 1.5, five more 2.0, five more 2.5. If you miss a shot or pot the white it goes back down one so 3.5 back to 3.0. Secret is to keep potting balls (clearly) and as you do so you earn time back to keep you on the table. When you get to a high multiplier you can really take your time.
Multiplier - For every 5 pots your score multiplier will increase by 0.5 to a max of 4.0. If you miss a pot or pot the white, it will decrease by 0.5.
Only just realised you can mark on the white ball at the bottom as to where you want to hit it. Backspin etc.. DOH!
