Let's face it, the net total of a lot of things in this picture is 24.
This puzzle calls for a constructive form of dicing. If only the hinges were visible! And the scores, for that matter.
24 dice nets, each with six different colours, have been unfolded and their bases fixed in place. Work out what the dice looked like before they were unfolded, and then look at each die's top colour and number in turn.
