With the multiplayer feature, you can put your skills to the test against other players like you! You can create an account or play as guest. There are 4 different board styles (a 2D diagram, two fixed 3D designs and a 3D rotatable board) to suit any style - from the playful kid to the serious tournament player. Our online chess game also features an opening database created by analysing 145,000 games from international tournaments. With 5 levels of difficulty and a behavior modeled to make human mistakes, this is a very fun game to play. SparkChess is an excellent way to get better at chess - learn the proper rules (including the elusive en-passant), practice openings, test strategies, use the board editor to recreate famous positions with FEN strings, replay famous games, import/export PGN games and databases (with comments and annotations) and let the computer help you. SparkChess is a free online chess game that allows you to practice chess against the computer and to engage in multiplayer online challenges, or to just watch others play.
