For seasoned Clever players and others looking for a challenge, there's now Clever cubed: Challenge 1! These extra score pads for Clever cubed differ from the sheets in the original game. The game rules 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 teal categories has been completely changed, and in the blue category, you now have to deal with mixed plus and minus signs. • Ages 8+ • 1 - 4 players • Playing time approx. 20 minutes
