  "description": "Number Fill-In puzzles are crossword puzzles with a fun twist — instead of words, every entry is made up of numbers!\n\nNo math skills are required. Just like a traditional Word Fill-In, all the entries are provided for you. Your goal is to fit them into the diagram, with entries running across and down, just like in a crossword puzzle.\n\nThe entries are mixed together, so you’ll need to use logic and the crossing numbers to discover where each one belongs. To help you get started, one entry is already filled in in every puzzle.",

    "intro": "Number Fill In gives you the quiet satisfaction of sliding number sequences into a crossword-style grid until every row and column clicks perfectly into place. It suits anyone who enjoys logic puzzles and wants a calm, screen-friendly challenge they can pick up and put down at will.",
    "steps": [
      "Open the puzzle and study the grid of empty cells",
      "Scan the list of provided number entries to get a feel for their lengths",
      "Use the pre-filled starter entry as your anchor point",
      "Work outward by matching entry lengths to available across and down slots",
      "Fill in the remaining entries until the grid is complete"

    "scoring": "",
    "ending": "A round ends when every cell in the grid is correctly filled with its matching number entry.",
    "tips": [
      "Start with the longest number entries — they fit fewer slots, so they narrow your choices fastest",
      "Count the digits in an entry before trying it in a slot; length mismatches are an instant rule-out",
      "When you are stuck, look for slots that share a crossing cell with a number you already placed",
      "The pre-filled starter entry reveals at least one confirmed digit in adjacent slots, so build from it early"

    "features": [
      "No math required — every entry is given to you; the challenge is placement, not calculation",
      "Crossword-style grid — numbers read across and down exactly as words do in a classic fill-in puzzle",
      "Built-in starter entry — one answer is pre-placed in every puzzle so you always have a foothold",
      "Mixed across and down — entries are unsorted, so finding the right slot is the heart of the puzzle",
      "Pure logic format — no timers or penalties create a relaxed, pressure-free solving experience",
      "Focused category — sits squarely in Puzzle and Trivia, designed for one clear kind of satisfaction"
