Rules of the game: You cast 4 sticks Yut sticks by turn and move your pieces. First player who moves all four of his/her pieces home then goal wins. If you cast a 4 or a 5 you can cast again. If you land on your opponent's piece, you remove their piece and you get another cast (this part seems buggy as you don't always get extra cast when you already casted twice this turn). If you land on your own piece, the two pieces are combined and are moved together. However if they are removed, they are removed together. You have to move in the direction of the arrows if you are standing on the corners and middle. If you are on the first space and you cast a -1, you can move backwards to home then goal next cast.
Since there are 4 sticks and one of which is marked "back," here are the chances of rolling each number (excluding Nak or no move):
Generally you want to stay out of your opponent's 2 to 3 range and put your own pieces behind theirs 2 to 3 spaces as much as possible to increase your chances of removing their pieces and getting another cast of the Yut sticks. If you have a piece on the 3rd space then you roll another 3, stacking another piece onto the 3rd space is a bad bad idea unless you are desperate.
