This is the awesome dice tower that James made out of Lego Duplo bricks.
(A dice tower is a device to ensure good dice rolls. Inside it are slopes and stuff to make the dice clatter around. The dice are dropped in the top, bounce off the obstacles inside, and come out the bottom and are usually then captured with a barrier. This prevents bogus rolls, dice rolling off the table, or dice rolling into game pieces.)
James and Al were using it to play Roma. For the record, the money was for pizza. We were NOT gambling. The Lego Dice Tower is for entertainment purposes only.
