Hi, I'm Krupali Nakrani. I have spent more than five years as a software developer and project manager, and these days I freelance from India. Grid Leveling is my own project, with no company or team behind it.

Everything here is written by me: the games, the level generators, the hints, the blog and this page. Reach me through the contact page or at gridleveling@gmail.com.

I have always liked logic games. Sudoku has been part of my day since childhood, and I still solve one every morning.

Queens, Wend, Patches and Crossclimb I first met on LinkedIn, with one catch: each gives you a single puzzle a day. When I finished it I wanted another, so I kept searching for other sites with the same games.

After a few too many searches I had a simpler idea: build the games myself, with no sign-up and nothing in the way. The bet was that other people who enjoy these puzzles would want the same thing.

The first playable version took two days. The name and the look took a week, and then I published it. The longer story is in the devlog post Why I Built Grid Leveling.

Five logic puzzles. Each has a shared daily challenge and a ladder of practice levels from small boards to expert sizes, more than 3,000 levels in all.

• QueensOne queen per row, column and colour. None touching.384 levels
• WendTrace paths to spell every hidden word. Use every cell once.1,110 levels
• CrossclimbSolve the clues, then order the rungs one letter apart.581 levels
• PatchesCut the grid into rectangles, one clue each.400 levels
• SudokuClassic 9×9 in five tiers, plus a quick 6×6 Mini.375 levels

Every daily is keyed to the same calendar day (Indian Standard Time), so every player in the world gets the same puzzle.

Nothing is copied from another puzzle service. Every level comes from a generator I wrote for that game, run offline, then checked by a solver before it ships.

A Queens, Patches or Sudoku board is kept only if it has exactly one solution, so it can be finished by deduction rather than guessing. Wend boards pass an exact-cover solver the same way, which is why there are 1,110 Wend levels instead of the several thousand the generator produced.

Crossclimb ladders come from a curated word list, with a clue written for every rung. Hints are built from the same rule engines, so a hint always points at a move the rules force, never at a stored answer.

• 🤝Honest about origins

  Queens, Wend, Patches and Crossclimb follow rules made popular by LinkedIn's daily games. Grid Leveling is independent and not affiliated with LinkedIn or Microsoft.

Grid Leveling is a hobby that costs money to host, so it may show a small number of adverts. Ads never sit on top of a board or interrupt a game.

The privacy policy lists every advertising and analytics service the site uses and how to opt out.

Each game has a how-to page with the rules and a worked example: Queens, Wend, Crossclimb, Patches and Sudoku.

The blog goes deeper, with strategy guides and comparisons written from building and solving these puzzles.
