The Dopplet so Clever Challenge Block is intended for the board game Twice as Clever!. This extra scorepad represents a fresh change for those who have become hooked on this addictive game. The new sheet layout, which is similar (but not identical), presents a real challenge that changes the restrictions and bonuses of each scoring section, while retaining all the rules of the base game.
If you thought it couldn't get harder or worse to earn bonuses, extra rolls, and ultimately a good score, or if you think you have mastered this game... or you simply need a change (but don't want to leave your comfort zone), this Challenge Block is the right choice.
Note: The Dopplet so Clever Challenge Block is not a standalone game and requires the Twice as Clever! board game to be played!
