The ThinkFun Solitaire Chess Magnetic Travel Puzzle is a single-player, logic-based chess game. It combines the classic chess moves with a puzzle element: each move must be a capture. The game consists of 120 challenges, ranging from beginner to expert, that gradually increase in difficulty as you progress. The magnetic board and pieces make it travel-friendly, and the self-contained puzzle booklet ensures portability. The goal is to clear the board of all pieces except one, using only capturing moves.
