You use the skip and hit chart in conjunction with the hit performance chart. Across the top of the skip and hit chart are the number games out for the drawings. Down each column are the number of hits for each number. The numbers listed down the left side are the numbers (balls) themselves. Here is how to use it. Have both the hit performance chart and the skip and hit chart side by side when you do this. Look down the 01 column on the hit performance chart (the column furthest right) and you will see numbers or ##. Numbers mean the number of games out for that number and ## means that number hit in the last drawing. So if you look down the 01 column and see that ball 07 is out 6 games, you would then go to the skip and hit chart and look down the left side for ball 07 and then look across the top (number of skips) for 06 and look down that column where it intersects ball 07. Let's say that number is 03. This means that ball 07 has skipped 6 drawings and then hit 3 different times in the last however many games your drawing cutoff is set to. If that number has hit many times for the current number of games out, you should consider playing that number. The skip and hit chart can clue you into any habits of hitting for a specific skip that numbers might have. The help file does a pretty good job of explaining how to use the charts. Good Luck.
