Dice Deduction is a brain-bending single-player puzzle game from Smart Games with a dice twist. Each challenge shows a pattern of dice faces, and you must position the transparent playing pieces so the black dots line up with the faces and the sums match the arrows. The game board holds four white dice faces, and you get twelve transparent pieces (four blank and eight marked) plus a booklet of 60 challenges with solutions. Every puzzle has just one answer, so you will know when you have cracked it. It exercises concentration, logic, planning, problem solving and spatial insight, and suits puzzlers aged 10 and up.
