Rfel

Rfel is a pure geometric traditional tenon puzzle game with authentic Chinese woodwork aesthetics. Different from ordinary texture jigsaw games, this gameplay relies entirely on precise edge concave-convex geometric matching rather than pixel or pattern fitting. In each level, you are given a fixed master board with unique tenon grooves and a set of independent modular tenon blocks. Players drag and rotate each tenon piece to align edge contours, match concave and convex sequences perfectly, and embed all modules into the board without gaps, offsets or overlaps. The game features procedurally generated level structures with increasing structural complexity, providing unique and solvable tenon combinations for every challenge. With minimalist logwood visual style, soft golden glow feedback for successful occlusion, smooth rotation and placement physics, and immersive quiet puzzle rhythm, it delivers a calm, satisfying and precise brain-training experience. The game is completely offline, ad-free and contains no in-app purchases.
