About
RectaFlow is a polished rectangle logic puzzle for quick focus sessions.
Draw rectangles around numbered clues. Each number is the exact area of one rectangle, and each rectangle must contain exactly one clue. Fill the whole board with clean, non-overlapping regions to solve the puzzle.
Play a campaign that grows from gentle 3x4 boards to dense 16x16 challenges, or choose Quick Play to generate a new board in Easy, Medium, or Hard. Hints, undo, reset, Dark Mode, subtle sound, haptics, and smooth drag controls keep the flow calm and focused.
RectaFlow is designed for relaxed puzzle play, with optional ads used for hints and unobtrusive banner placement outside the game board.
