What’s new in SparkChess 15

Access our online Endgame Tablebase

This is huge and it’s been on our to-do list for years!

If you are unfamiliar with the term, tablebases are enormous databases that enable chess engines to play accurately in the endgame phase, when there are only a handful of pieces left on the board.

For most people, even professional chess players, downloading and installing these huge databases would be impractical, but SparkChess 15 can use our own cloud database and when there are 5 or fewer pieces left on the board, it can find the best move instantly! (Claire and above can use it and you can also use it via Help/Coach).

Learn and practice openings

Learn major chess openings (over 100 variations in total!) with Openings Explorer. Simply choose to practice against an AI opponent and select an opening from the dropdown. You’ll be shown arrows for moves that are part of the selected opening, allowing you to learn it quickly and to explore different variations.

Snapshot and 3D improvements

The 3D mode has been improved with more detailed models, better lighting, and a dynamic depth-of-field effect that has to be seen in full to be appreciated.

And with all these gorgeous visuals, we just had to add a snapshot feature so that you can save the board as an image.

And more!

  • Better AI: Opponents play openings more naturally, and are better at adapting their response to the player.
  • More languages: SparkChess is now available in 7 languages: English, German, French, Italian, Dutch, Spanish and Romanian. 
  • Team management: Admins can now lock their team to prevent people from sending join requests. You can now search/filter teams from the list to find the one you’re interested in.
  • Refinements: Interface and board improvements, such as better board lighting, modified chat window to better accommodate devices with on-screen keyboards, and others.
  • More: Many other improvements and bug fixes.

We hope you’ll enjoy playing SparkChess as much as we enjoyed building it! Your support for 12 years enables us to keep the development active.
