Number Crossword has 3 grid sizes, 3 speed settings, and 27 medals to chase. Here's how the progression works, plus 2 tips to level up faster.
Number Crossword isn't just one puzzle — it's three grid sizes, three speed settings, and 27 medals waiting to be found.
The level you pick sets the grid size: Level 1 is a 5x5 grid, Level 2 steps up to 9x9, and Level 3 is the full 9x13 challenge, where far more equations have to check out at once.
Separately, the difficulty sets the time pressure. Easy removes the clock entirely — solve at your own pace. Medium adds a moderate time challenge. Hard turns it into a genuine race.
Clearing puzzles also builds toward DigitGrid's medal system: 27 medals in total, 9 for each difficulty tier. Every solve adds to a running points total too, so there's always a number to beat.
Two tips to level up faster:
• Start on Level 1 before jumping to the 9x13 grid — the smaller board builds the deduction habits you'll need once the equations multiply.
• Look for the row or column with the fewest empty slots left, and solve that one first. It narrows down what's possible everywhere else on the grid.
DigitGrid is free and works offline. Ads are kept light — a small banner, an occasional break between levels, and an optional video only if you tap Hint more than once in the same game.
