 On a turn, the computer rolls two six-sided dice. You then write the results, e.g. 1 and 4, in empty spaces in the provided pattern, with each number being in the mirrored space of the other. If, say, you place the 1 in the leftmost space of the top row, then you must place the 4 in the rightmost space of the top row. The position you choose on the left side of the split also determines the position where to put you other number on the right side of the split.
 
-After 22 dice rolls, your pattern will be filled. Each 1 on its own — that is, with no other 1s orthogonally adjacent — scores 1 point; each set of two 2s that have no other orthogonally adjacent 2s score 2 points; and so on up to a set of six 6s with no other orthogonally adjacent 6s being worth 6 points.

 There are two special cases: 
 A starred space is present on each half of the pattern, and a scored group that contains this starred space has its points doubled.
