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