Paper Corners is a Shakashaka logic puzzle: place black triangles in a grid until every white region forms a rectangle. Some rectangles sit straight; others tilt at 45 degrees. The numbered squares tell you how many neighboring squares need triangles. Solve 222 pages in twenty-two chapters. Start with small boards, then work through larger pages up to 10 × 10. Choose a page by difficulty or follow the chapters in order. A short introduction teaches the rules. Four optional technique lessons let you practice triangle clues, white squares, and rectangle edges. If you get stuck, a hint marks a cell and explains the deduction. Undo and redo let you revisit any move. Play a free daily page every day, or choose an earlier date from the daily archive. An unfinished daily page stays available after midnight.
