🕶️ A view of its UI during a 4-player online game (of Magic: The Gathering) I attended as a spectator. The main part of the UI is divided into 4, showing for each player the cards placed on the mat and its parameters. On the right-hand side of the UI, several zones (which can be detached from the UI), including Card Info (the spectator can select a card on the mat with a mouse hover to read it better), Player List (selecting a player also opens a menu with actions on that player, such as chat, add to friends list, view games, etc.), Messages (from the UI specifying player actions). At the top of the UI, tabs allow you to build a Deck by selecting cards online, view Servers by game type, view Replays, attend (and participate in?) several games simultaneously. 📚️ Cockatrice is a libre, multi-platform virtual tabletop card game (on a client/server model) whose (server-based) design prevents users from manipulating the game to gain an unfair advantage. Features include Deck design (cards downloaded from the interface), a well-designed lobby client allowing different types of game (Magic: The Gathering, Poker, Pokemon, YuGiOh, Hearthstone) with or without spectators, tabbed navigation between multiple games, chat, replay of games, offline solo play, themes, sound effects (deactivatable). Excellent!
