How to Play Sudoku: Your First Solve

People often (wrongly) assume that sudoku is a math game simply because it has numbers. But it’s not, in fact, it has absolutely nothing to do with math, to prove this point, let’s look at a simple 4x4 grid of emojis.

There are only 3 rules and you can try to solve it yourself!

The Rules

  1. No row can have the same emoji repeated.
  2. No column can have the same emoji repeated.
  3. No 2x2 subgrid can have the same emoji repeated.

   1. row
   2. column
   3. 3x3 subgrid (also called a house)
