CALENDLE

Welcome to Calendle! 📅

New puzzles every day.

• 🎯 Goal: Cover the whole board with the 8 pieces, leaving only today's month and date showing.
• 🧩 Place: Drag a piece from its tray onto the board. Green outline means it fits, red means it doesn't.
• 💡 Hints: Tap 💡Hint (or press H), then tap a tray to reveal one tile it covers. Puzzles have many solutions, but the hint only helps with one!

Let's play!

🔍 Place more pieces first

• 🧩

  A hint works best once the board is fairly full. With only a few pieces down, the search can confirm very little and will mostly just return them to the tray.

Keep placing

🔍 Search anyway

🔍 Fewer pieces kept

• 🔍

  This search can keep only 0 of your placed pieces which is fewer than the 0 currently highlighted. Applying it returns the others to the tray.

🔍 Apply anyway

Keep current hints

📜 Rules

Fill the board so every rule below is satisfied.
Warning: This mode can be very difficult and is still in testing.
