In Splitter, you must group numbers together to score points — two 2s, three 3s, and so on — but you're placing two numbers at a time, so things won't always work out. On a turn, someone rolls two six-sided dice. Each player then writes the results, e.g. 1 and 4, in empty spaces in the pattern, with each number being in the mirrored space of the other. After all spaces are filled, you calculate the score. 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. Whoever has the highest score wins.
