🤖 LDRBot

---

💡 Overview

LDRBot stands for LinkedIn Daily (games) Ranking Bot — a Telegram bot that automates score tracking and leaderboard generation for LinkedIn's daily puzzle games ( currently, Queens, Tango, Zip, Crossclimb, and Mini Sudoku).

Each Telegram group becomes its own independent competition. Members can submit their puzzle results either by uploading screenshots or by sharing the result message directly from LinkedIn. LDRBot uses OCR to extract solving times from images to build a daily ranking automatically. Alternatively, it can parse the shared text.

🦾 Try It Out

Add LDRBot to your Telegram group: @LinkedinDailyRankingBot

Each group is treated as a standalone competition — just invite the bot to your group and you’re ready to go!

⚙️ How It Works

When you add LDRBot to a Telegram group, that group becomes its own independent leaderboard and competition space. Each day, members of the group can submit their results for LinkedIn's puzzles (currently: Queens, Tango, Zip, Crossclimb, and Mini Sudoku) in two ways:

1. Upload a screenshot of the completion screen — LDRBot uses OCR (powered by OpenCV and Tesseract) to automatically scan and extract the game type and solving time.
2. Share the result message directly from LinkedIn — LDRBot parses the text to extract the same information.

Once processed, the time is recorded for the current day and associated with the correspondent Telegram user ID.

As group members submit their scores, LDRBot keeps track of who’s already participated and waits for everyone to submit. Once all registered players have sent their times, it automatically recalculates and publishes the daily leaderboard. Alternatively, any member can run the /ranking command to manually trigger a recalculation at any time.

If not everyone submits, LDRBot will still calculate and publish the results at the end of the day, including only the times that were received. This ensures the competition continues smoothly even if someone forgets to post their score.

Each group maintains its own isolated set of scores, players, and competition history — meaning users can participate in multiple groups independently. Leaderboards reset daily, so every new day is a fresh challenge for members to compete, improve, and (hopefully) brag.

Note

Only group messages with commands or screenshots are processed.
Private message support is under development.

🖼️ Screenshots

LDRBot uses OCR to read your submitted screenshots and extract the game and solving time. For best results, try to capture the colored square that shows the game result as clearly as possible, and avoid overlays like confetti or cropped images.

🚀 Getting Started

Requirements

• A Telegram account
• A Telegram group where you have permission to add bots

Setup

1. Add the bot to your group
   LDRBot will start tracking scores and players from the moment it's added.

2. Configure the bot (optional)
   By default the bot will track all games supported. Admins can use /configure to choose what to track as well as configure other bot settings.

3. Submit your LinkedIn score
   Upload a screenshot or share the result message from LinkedIn. LDRBot will extract your time and game, and track it for the day.

4. Manage your score (optional)
   Use /delete, /deleteall, or /override (admin-only) to modify the results if needed. Useful for correcting misprocessed or mistaken submissions.

5. Watch the leaderboard evolve
   Once everyone submits (or at day's end), LDRBot will post the updated rankings.
