Hello hojimoe,
this particular program uses one line; a combination of two lines; a combination of all three lines only and each digit or digits must touch one or all three lines without skipping!
eg., winning sample...174:
123
297
844...you can see...174...on three lines and none are skipping to another line.
227
174...
890---174 is in the middle and on one line:
171
446...174 is on two lines:
The idea is that the winning digits can be on any of three lines in any order! If you see a digit or two above the indicated lines, they will not work. Must be on one, two or all three lines...WITHOUT SKIPPING A LINE! At times I might add a column or two to the basic four columned lines but not to fret! The same principal is in force. Try not to read into this program anything other than what you see!
This info should help you and others whom are trying to understand what's happening!
