Block Master is an independent browser-based puzzle brand focused on a free 9×9 block-placement game and practical strategy tools. Players place sets of three shapes on the board, clear complete rows, columns, or 3×3 boxes, and track their best scores locally without creating an account. After each move, the game displays board-health signals to help players assess available placements, open space, lanes, and potential trouble spots.

Beyond endless play, Block Master offers a board analyzer for testing specific positions, a daily puzzle with the same piece sequence for every player on a given UTC date, and 18 reviewed practice boards. Its strategy library covers topics such as planning all three pieces, preserving space for long bars and L-shapes, avoiding isolated holes, and understanding scoring and board-health calculations. The tools and lessons use the same game engine, making positions reproducible and explanations grounded in actual board states. Progress remains on the player’s device, and the project states that it has no accounts, public leaderboard, or screenshot uploads.
