Ice Cubed Puzzle Game

Forty eight frozen number puzzles...work out where to position each cube and solve the puzzles!  Six ice cubes, each one featuring numbers on four sides.  Each of the forty eight multi-level puzzles requires you to correctly position up to five of the colour-coded ice cubes in a tower, so that the numbers on the four outer faces vertically add up to the totals shown at the foot of each of the four sides of the tower...all at the same time.  For 1 player, ages 7+
