Winpool is a windows game that was created from the code that was written for Xpool (which is an X windows version of this game) which simulates a billiard game by using an approach called Discrete Element Methods(DEM).
If you know how to play pool, excellent!, if you don't, here is all I can say (and know) about this game: With the current setup, we have two sets of balls, first set is ball # 1-7, second set is ball # 9-15. whoever gets his/her balls in first and then gets the black ball in last wins. We don't have automatic scoring right now, so whoever wins is supposed to increase his/her score by clicking on his/her '+' button (under Scores). If you want to see where your ball will go, click on 'trajectory ' button to get a trajectory of your shot. The cue stick length determines the hitting strength, so if you want to hit harder, change your cue stick length by moving your mouse away from the white stick.You don't have to click on the white ball to start stick handling you can click anywhere on the table and start stick handler. The white ball goes to the opposite direction relative to the cue stick.
