Terrible animation just like Akagi it had the most dreadful character sets you can find. It also has relatively simple scenery and motion for animation. Thus it all didn't appeal at all. The most annoying parts included the emotional scenes that show the character surrounded by "zawa" and then swirling lines going around them. On top of this poor animation they choose to use quite a few flash backs and recaps making it even worse. On the plus side just as in Akagi the focus stayed on the gambling and mind games this also happened in Kaiji. Nonetheless I don't feel as forgiving as I once was for this kind of animation.
This was even more annoying. First of all the "zawa" fucking gets to you and annoys the hell out of you. By the end of the series I began skipping over any part that had the zawa sound in it. I hated it... Absolutely dreadful. Moreover the announcer for the beginning and end of the episode also pissed me off. Do they really expect me to not remember what happened and even if I didn't I don't really want an annoying voice to remind me every episode what happened. I don't know who enjoys thoses effects but I certainly don't. The opening and ending were both uninteresting. The OST and voices were also mediocre and I couldn't find myself giving any praise to the work.
