Why did you change the board design?

The board design of SparkChess remained virtually unchanged for the most part of a decade. This results in familiarity, which is good, but when we updated the graphics in 2017, some users were distraught.

We believe the new fixed board design introduced in SparkChess 10 improves contrast and presents a more elegant chess set.

We commissioned a professional survey. 400 respondents living in the US, from all walks of life, were asked if they preferred the old or the new design. The new design won categorically, 62% vs 38%. The margin of error of the survey was 5%.

How long did it take to make the game?

The original version took about three months, not including the time spent studying algorithms. The game is in active development since 2008. We make one major release each year and a few minor releases.

What are the engine technical specs?

SparkChess uses a chess engine developed in-house with negamax, principal variation, iterative deepening, aspiration, quiescence, killers, history heuristics, null moves, razoring and transposition tables. It has an opening database with about 15000 moves.
