Score Pads Clever to the 3rd Power Challenge (2 pieces)

For seasoned Clever players and others looking for a challenge, there is now Clever to the 3rd Power: Challenge 1! These additional score sheets for Clever to the 3rd Power differ from the sheets of the original game. The rules of the game are otherwise the same, but must now be used on a score sheet that works slightly differently. For example, the layout of the yellow and blue-green categories has been completely changed, and in the blue category you must now take into account intertwined plus and minus signs.
