To put it mildly, whoever wrote for your Spades game has no clue how the game is played. The computer continually takes extra tricks, an average of 2 per hand. Also, the computer does not know how to balance setting someone going nil, to getting their bid. Routinely, it prioritizes getting its bid and not setting someone going nil. And another thing, why doesn't the computer understand when to throw off. It constantly takes the trick if it has trump and accounts for more taken than necessary. Here is an idea. Find an old sailor that has been playing Spades for years to teach your computer some things.
