Cover of Knight

Cover of Knight

Cover of Knight is a puzzle designed by Néstor Romeral Andrés and implemented by Garage Imagina which allows you to play online for free through the web version or apps for iOs and Android.

It is a generalization of the Chess Covering Problem that adds ‘holes’ to the board.

Place pieces on the board so that all the available squares -even those occupied by your own pieces- are under attack and the total value of the pieces used is the lowest possible. Records are updated automatically.

Cover of knight is a new way to play chess that will make you a better chess player.

There are two modes of play:

  • Basic: You can use each piece as many times as you want and with no placement restrictions.
  • Advanced: You can only use the 16 pieces of a standard Chess set, pawns can’t be placed on the first and last row, one bishop per square colour.

Play chess online for free

Cover of Knight has an html5 version of the game that will allow you to play chess for free and solve the puzzles we present you from your browser.

Game levels

We have three levels of play: basic, intermediate and advanced so you can choose the level of play that best suits your level.

Improve your level as a chess player

The objective of Cover of Knight is to attack all the squares of the board with the least amount of pieces possible while avoiding the obstacles that we place on each board, which is a fantastic training to improve your chess level.


The best results of each board are uploaded to our records panel, so you can compete with the rest of the players from all over the world. So you can try to get the record in a board or be the best in the sum of all the best records, both in basic and advanced level.
