How to Play

  1. 1Pick a world (Addition, Multiplication, Mixed, Expert) and start a run
  2. 2Tap a cell to select it; the active across/down clue is highlighted
  3. 3Enter digits with the on-screen keypad or your keyboard (0–9, Backspace/Delete to erase)
  4. 4Use intersections to deduce shared digits and complete the full grid
🧠

A number crossword where every clue is math. Solve across and down answers as digits, and use intersections to deduce the whole grid.

About This Game

Cross Numbers is a fresh take on crosswords where every clue is a math challenge and every answer is a string of digits. You solve the grid by making numbers intersect, just like a crossword, except instead of words, you’re building correct numerical answers across and down.

Each run starts by choosing a world: Addition, Multiplication, Mixed Operations, or Expert. Tap any white cell to select it and the game highlights the active clue path. Enter digits with the on-screen number pad (or your keyboard). Intersections matter: a shared digit must satisfy both an across and a down answer, so one solved clue often unlocks several others.

The hook is replayability. Worlds offer endless procedurally generated runs, stars for fast and accurate solves, XP and streaks for momentum, and gradual world unlocking as you improve. It’s quick to learn, satisfying to master, and built to scale beautifully from desktop to mobile in embedded/iframe platforms.

Goal

Solve the grid by answering math clues across and down. Every intersection must match, so you use deduction plus mental math to complete each run with speed and accuracy.

Difficulty

Pick a world: Addition, Multiplication, Mixed Operations, or Expert. Each world has endless procedurally generated runs. Use Shuffle for a fresh sequence, or Continue (∞) to jump into the next run. As you earn stars and XP, higher worlds unlock and clues introduce deeper patterns.
