Have they tried:
Stone 2 in cup 1 and stone 4 in cup 2? (one:two)
Stone 4 in cup 1 and stone 8 in cup 2? (one:two)
The reverse of either of the above? (cup*contents=cup*contents)
Stones 2 and 8 in one cup and stones 4 and 6 in the other? (contents=contents)
Reading the clues?

An interesting question. I don't think they'd hold Arty's interest for very long...
