Nice work, I really like that. I haven't received the game yet, so my idea was just to get one of those really small travel chess sets with magnets in the pieces. Have the player board sit on something metal (not permanent) thats flat...figured the dollar store/ thrift store would have it. but your idea looks good, if you did all the player boards, do you think every thing would fit in the box still?
I bought a 10mm square arc punch and hope to make a version with individual slots for each cube using two layers of chipboard. I can see I will definitely have to space the numbers out further than this or the original track did.
