How to Play Number Grid

Rules

  • Every row and column is an arithmetic equation.
  • Equations are evaluated strictly left-to-right (no order of operations).
  • Fill in missing numbers (and operations at harder levels) so every equation is correct.
  • Each puzzle has exactly one solution.

Cell Types

  • Square cells — numbers (tap to enter a number)
  • Round cells — operations +, −, ×, ÷ (tap to toggle)
  • = signs separate the equation from its result

Keyboard Shortcuts

About expert number grids

Five-by-five grids with ten equations. Numbers range up to 100, and 6–10 cells are blank — a mix of number and operation blanks. Each equation is longer too: five operands separated by four operations, so you often need to compute intermediate values to figure out what fits.

At this size, working from both ends of an equation becomes essential. If you know the starting number and the final result, the middle operations and values are heavily constrained. Expert grids take 8–15 minutes and are suited for adult puzzle solvers who enjoy KenKen or Kakuro-level challenges.
