Boardle

About Boardle

Boardle takes a chess tactic and turns it into a guessing game. Rather than playing one move and getting a reply, you write out the whole sequence: your move, the reply, your next move and so on, filling a row of tiles in standard algebraic notation.

When the row is full you press submit and the tiles change colour. A green move is in the solution and in the right place, a yellow move is in the solution but in a different spot, and a grey move is not part of it. You then try again with what you learned, over several attempts.

A move only counts when its notation is exact, so a capture that gives mate must be written with the mate sign. Besides the standard puzzle there are Boardle Mini, Boardle Mega and Boardle Maxi, which change the length of the line. The positions are taken from lichess.

It suits chess players who already read notation and want a daily tactic with a twist, and Wordle players who know the moves and want something other than letters.

How to play Boardle

1. Open Boardle and pick a size: Mini, Boardle, Mega or Maxi.
2. Play moves on the board for both sides; each one fills the next tile in algebraic notation.
3. Use undo to take back a move before the row is full.
4. Press submit and read the colours: green is right and in place, yellow is in the line but elsewhere, grey is not in it.
5. Use the feedback to enter a better line on your next attempt until you find the solution.

Tips

• Look for checks and captures first: daily tactics usually start with a forcing move.
• Write the notation exactly, with + for check and # for mate, or a correct idea will show as wrong.
• A yellow move often means the right idea in the wrong order, so try swapping it with its neighbour.
