What carries over and what is different
Both puzzles ask you to cover the whole grid with non-overlapping shapes, one clue per shape, with every cell used exactly once. A Patches clue can show a size, a shape icon (square, tall, wide or free-form), or both. Rect Rush uses number-only clues, so every deduction comes from areas, board edges and neighboring rectangles.

How a Rect Rush battle works
Choose 2P, 4P or 8P in the lobby and you get matched into a battle. Both players in a round get the same boards, rules and time limit, play their own attempts, and the higher score wins; 4P and 8P battles are knockout brackets of two-player rounds. Play is asynchronous, and your results count toward the Rect Rush leaderboard.
