Hi,
I have been searching far and wide and have yet to find a place other than the Xeno site where I can pick various colors not offered on there.
It appears Xeno games will be going out of business soon. So they won’t be releasing any new colors.
The colors they currently offer I already own. I am looking for yellow, blue, red pieces etc that have since been discontinued.
I am curious if anyone has these colors and are willing to sell them to me.
I have tried ebay and every so often something comes up. However its hard to find them.
At this point you need to buy games that those color pieces came in if you want those color pieces. Good Luck!
