Made https://t.co/3ZZ01J0lDI a while back to test fetching from the lichess puzzle db. Each day brings a new checkmate ladder. Stats are saved for logged in users.
Could expand to let users create their own custom daily routines (based on ratings and themes)... 🤔
Other ideas?

💡ChessMint Feature Spotlight: Quick Sheet — chess training material the fast way

Running a group lesson in 20 minutes and need a warm-up puzzle sheet for your students? About to commute to school/job and want to work on your calculation skills on the way?
ChessMint's Quick Sheet feature has you covered.

Set the difficulty, choose a theme (e.g. Fork, Pin, or Mate in 2), and hit generate.
➡️ ChessMint then pulls fitting puzzles from the Lichess puzzle database and creates a print-ready PDF for you. All within seconds. ⚡️

No puzzle hunting, no formatting troubles, no friction.

Depending on your layout preferences, you can fit 1, 2, 4, 6, or 12 diagrams on your sheet. You can also append the puzzle solutions to the to the document with one click.

Download the generated PDF, print it, done. ✅

Finally added SVG icons to the menu buttons. Such a small and simple improvement, but the website looks and feels so much nicer now.

(Granted, the order of the buttons still does not make much sense)

@OyeyemiFawole Hi, great to hear!

What would be an example of how you would use this feature / in what context? And maybe an example of what the resulting sheet would look like?

Might be tricky to implement, so I have to make sure I understand it 100%

Thanks for the feedback!

[ChessMint @chess_mint]
