Puzzleship Number Fill-In

Number Fill-In is a daily crossword-style number puzzle where your mission is to fit every number from a given list into the grid so that each one slots into place exactly once.

You're presented with a blank crossword grid and a list of numbers grouped by digit count. Your job is to figure out where each number belongs. Some placements are obvious. Others require working backward from constraints.

• Numbers are grouped by length: 3 digits, 4 digits, 5 digits, and so on.
• Each number from the list must be placed exactly once.
• Click a space in the grid, then select a number to fill it in.
• Look for spots where only one number from the list fits the available slots.
• Six different puzzles drop every day.

Why we like it:

• ✅Scratches the same itch as a crossword but uses pure logic instead of trivia.
• ✅That satisfying moment when the last few numbers cascade into place.
• ✅Quick enough for a coffee break but still makes you think.

Hint: Start with the longest numbers or the rarest digit patterns. If you only have one 6 digit number, find where it goes first. Let the constraints do the heavy lifting, and the shorter numbers will fall into place.
