4×6

4×6 is a daily card-sorting puzzle where your mission is to unscramble a jumbled board until every color sits alone on its own shelf.

Each puzzle starts with mixed-up cards across a set of shelves. You can only pull cards from the right end of a shelf, so every move opens up some options and closes others. A short warm-up walks you through the basics, and a few one-time tools are there when you get truly stuck.

• Tap a shelf to lift its rightmost card, then tap another shelf to send it there.
• A card can only land next to the same color, or on an empty shelf.
• A move counter tracks your progress against a par target.
• The round ends when each color is sorted onto its own shelf.

Why we like it:

• ✅The rules take seconds to learn, but the planning runs surprisingly deep.
• ✅The warm-up makes it easy for a total newcomer to jump in.
• ✅Every puzzle feels like a small, satisfying logic knot you can untie.

Hint: Before you move anything, look at which cards are buried under others on the right. Clearing one shelf early gives you a safe parking spot, so you can save your one-time tools for the tightest moments.
