With the lower one you stick the dice in 2 x 4 dice square blocks and stick both blocks together so only 3 sides per dice show. Make sure that sides 1, 2 and 3 are showing. 6 dots per dice x 8 dice = 48 dots.
With the higher one make a lightning bolt shape and manouvre the dice so that 1 and 2 are concealed. On the end ones only the 1 should be concealed. The sum is 20+18+18+18+18+18+18+20=148.
Simple!!!
