Step 1 of 6

Look first

This is the position at the start of every game. White is at the bottom, Black at the top.

Every square has a name: first the letter, then the number. The king is the tall piece with a cross on its crown. Tap the square where the white king stands.

Arrow keys move the focus across the squares. Enter or Space marks a square or removes the mark.

Which piece should the pawn become?

Step 2 of 6

Decide

Before the game begins, check that the board is the right way round.

From White’s side, h1 is the square in the bottom-right corner. What colour is it?

Arrow keys move the focus across the squares. Enter or Space selects a piece and moves it to a highlighted square. Escape cancels the selection.

Step 4 of 6

How squares get their names

The board has 64 squares, alternating between light and dark.

The vertical columns are called files. They have letters from a to h.

The horizontal rows are called ranks. They have numbers from 1 to 8. White starts on ranks 1 and 2, Black on 7 and 8.

A square’s name starts with the letter, then the number: e4 is on the e-file and the fourth rank.

Key idea

A square’s name starts with the file’s letter, followed by the rank’s number.

When does this apply?

This works from either side of the board. When the board is the right way round, the bottom-right square is light.

Step 5 of 6

Different side, same names

Rank 8 is now at the bottom, and the h-file is on the left.

Now you see the board from Black’s side. White has moved a pawn. Tap the square it is on now.

Arrow keys move the focus across the squares. Enter or Space marks a square or removes the mark.
