This electronic chess game was rated the best due to its superior performance in evaluations by the Hammacher Schlemmer Institute. Multiple games were play-tested by members from the DePaul University chess club who assessed each unit for its performance, ease of play, and build quality, and this model won in all three categories. Panelists described it as providing a level of competition that was “pretty well matched to my online chess rating” and being comparable to real life tournaments. It was considered the easiest game to operate because its pieces moved “gracefully and accurately” on their own using a “well designed app” that was “clear to navigate.” This game was also rated superior for its durable rosewood construction and stability.
