Card Tracker

Tracks opponents' resource cards on colonist.io from the game log. For practice against bots. First game free.

Card Tracker reads the game log of colonist.io while you play and shows, in a small floating panel, which resource cards each player is holding. Made for practice games against bots. It only uses information that every player can see in the game log. Using it in games against other people may break colonist.io's terms of service. What the panel shows - Every player's hand: lumber, brick, wool, grain and ore, plus the total - Uncertain cards after a hidden steal, with the range, the expected value and the exact odds on hover. Later moves (building, trading, discarding, monopoly, trade offers) narrow the possibilities down automatically - What each player can build right now, either for certain or with a probability - Development cards: knights played, hidden cards per player and the chance that they hold at least one victory point, the remaining deck and the odds for your next card - Dice statistics compared to the expected distribution - Cards left in the bank, with a warning when a resource runs low Details - Works when colonist.io is set to English (the game log is read in English) - Light and dark design, switched with one click in the title bar - The panel can be moved and collapsed; collapsed, it still shows every player's card count - Interface in English and German, following your browser language - No ads, no analytics Privacy The extension only runs on colonist.io. The game log is processed locally in your browser and never sent anywhere. To check whether you have unlocked the extension, it exchanges a random key with ExtensionPay. Your email address and payment details are only entered on the ExtensionPay and Stripe pages when you buy or log in. Your design choice and unlock status are stored locally in the browser.
