As others have said, you against the three bots

First of all, since two Yosemite updates ago, this won’t even work anymore.

Second of all, you get the stupidest bot of them all such that at times it seems that it is you against the three bots. You go nil, but you better have an excellent nil hand, as your partner bot will lead low and play low and set you, incredibly stupid play.

Save your money. I don’t see any good spades programs for the Mac, don’t know why that is the case.

Judicious Nil about Spades.
