Pixactly is an independent pixel estimation game designed specifically for designers and frontend developers. Launched in 2014, this unique browser-based game challenges players to make visual guesses of width and height, providing instant feedback on accuracy and generating corrections based on performance. The game consists of five rounds that progressively increase in target sizes, allowing users to measure their pixel accuracy while enhancing their design skills.

Maintained by David, one of its original co-creators, Pixactly is a long-term web project that prioritizes user engagement without requiring accounts or leaderboards. Users can explore practice guides, which are continually updated to address various aspects of interface dimensions. While Pixactly may utilize advertising to support its maintenance, it remains committed to preserving the integrity of its game mechanics and user experience.

This platform is not intended as a medical vision test or a psychometric tool, but rather a fun and practical way to improve visual estimation skills in a design context.
