That part of the game (game rule logic) usually works (with some bugs) but the UI suffers from extremely poor UX and is unresponsive. This is endemic throughout the game including area where game rules aren`t being evaluated.

Add on poor server stability that causes players who paid to participate in events to get kicked out and loose due to the issues and the experience is horrible.

It`s a credit to the quality of the card game that such a crappy experience is even played at all.
