Portable chess sets are compact versions of the traditional chess game, designed for easy transport and play. They often feature lightweight materials and foldable designs, making them ideal for travel, outdoor activities, or casual play. Many portable sets come with magnetic pieces to prevent them from moving during transport. These sets can vary in size and style, from small travel kits to larger, more elaborate designs. Some include built-in storage for pieces, while others may have a simple board that can be laid out on any flat surface. Portable chess sets are popular among both casual players and serious enthusiasts.
