This has been a complaint I've heard many times before and I used to dismiss it as players being unfamiliar with computerized randomization vs real-life card shuffling. However I've started noticing patterns in the way OCTGN randomizes the cards after a single shuffle, as a test-. This definitely requires extensive investigating to see if there's actually any flaws in the algorithm of if I'm just crazy.

I have a 30 card "singleton" (only one of each card) deck I've been using for game def testing and I've noticed unusually frequent instances where a the same two cards are extremely likely to show up within the bottom 3 cards vs anywhere else. This always happens during a single shuffle, and OCTGN is completely closed down between shuffles. So its possible that OCTGN is using a seed-based algorithm that isn't completely randomizing the seed?
