NMBR 9++ takes your NMBR 9 experience to the next level. Finally you can close unwanted holes and turn and turn the number tiles as you please. If you don't want a tile in your display, you simply reject it in the “2 out of 3” variant. NMBR 9 ++ is not a standalone game and can only be played in combination with the base game NMBR 9. It includes three expansion modules and two game variants. Thanks to the additional material, the basic game can now be played with five or six people.
