Colonist Card Tracker – Catan card counter

Colonist Card Tracker shows, while you play on colonist.io, how many cards of each resource every player holds. • Counts every distribution, build, trade, discard and monopoly. • When an opponent steals from another opponent and the card is hidden, it computes the probability of each option and refines it with later moves. One click switches to the expected value. • Development cards: how many each player holds and which ones they have already played, shown as cards. • Bank and remaining deck, plus a "More stats" section: dice histogram against the count the odds predict for every number, sevens, most rolled number. • Checks the count against the card totals sent by the server and flags any mismatch. • Interface in 15 languages, light and dark themes. Works whatever language the game is set to and survives a page reload mid-game. Open research. This extension is free. In return, using it requires accepting that it stores the history of your games (moves, trades and chat) anonymously: every player name is replaced by a code before anything leaves your browser, and the key that generates those codes never leaves your installation. The data is collected exclusively for research on decision-making and negotiation in the game. You can withdraw your acceptance at any time in Options. Unofficial tool, not affiliated with Colonist. It only reads the traffic the server already sends to your browser; it sends nothing to Colonist and does not modify the game.
