Partly it broke down because the penalties seemed wildly disproportionate at times, partly that it stopped being an interesting challenge. A bit like playing set with the person who has been playing it already for 15 years. It seemed to have a very heavy luck element, especially when given the fact that not grabbing on a match is a far better option than accidentally grabbing when it isn't a match. And it might be the case that playing with only 3 players is a degenerate case, and that it works much better with a fuller table.
