Puzzle board games challenge players to solve spatial, logical, or optimization problems. Unlike traditional puzzles, they add competitive or cooperative elements, time pressure, or evolving game states. Examples include Azul (pattern completion), Cascadia (ecosystem arrangement), and Sagrada (dice placement in a grid).

Great puzzle games include Azul (tile pattern building), Cascadia (habitat and wildlife matching), Sagrada (stained glass dice placement), Patchwork (Tetris-like quilting), Project L (polyomino puzzle race), and Calico (quilting with color and pattern matching for cats).

Polyomino games use Tetris-like pieces of different shapes that players must fit into grids or boards. The spatial puzzle of fitting pieces efficiently is the core challenge. Popular polyomino games include Patchwork, A Feast for Odin, Barenpark, Isle of Cats, and Project L.
