Brad could always find another copy with missing pieces and parts, and create a whole game. I did that a few months ago with a Jeopardy! 10th Edition I found in impeccable condition, but it was missing two dollar slides. Enter a 4th edition I have had for close to 20 years, which is missing many more pieces. Ta da, complete 10th Edition. At least in this area, I have seen more than my fair share of Endless Concentration games at thrift stores. Hopefully the hunt for another copy to either complete your current copy or to keep as a playable version is not that difficult.
