You're welcome :) That's a nasty trick though but it is actually designed to be used that way, Lego has all kinds of interesting tricks.

Come to think of it this is an interesting game in the making, much better than most (or even all) games that lego makes:

Given x pieces from some set you get to take turns trying to make the highest combination, or, alternatively, all kids at a party are handed the same lego pieces and the winner gets some prize.
