Number twins–Delete balls by matching up twin pairs that add up to the chosen number. Balls can only be matched by an invisible line that doesn't make more than two turns. (No other balls can be in the path.) Another way to say this is to say that balls can be matched by either one or two or three straight lines.
Kitten Match-Choose your kitten color, join a game, and score points by correctly matching numbers to create the given answer.
