Boxed: Shikaku Logic Puzzle

Boxed is Shikaku, the Japanese logic puzzle also called Rectangles. Split the grid into boxes so each box holds one number, and that number is its area. Drag to draw a box, tap it to remove it. Every board has exactly one solution, and you can reach it by reasoning alone. DAILY Three new boards every day, the same for everyone: Daily 5×5, Hard 7×7 and Expert 10×10. Keep your streak going and share a spoiler-free card of your solve. ENDLESS Pick a size from 5×5 to 12×12 and a difficulty, then play as many boards as you like. JOURNEY 12 chapters and 372 levels. Each chapter teaches one idea: edges and corners, big numbers, long strips, crowded boards, giant boards. Finish all 30 levels of a chapter to open its Impossible board. TIME TRIAL Clear as many boards as you can in three minutes. SHAPE TRAPS On Hard and Expert boards, some numbers look like they want a square but only fit as a long strip. A hint shows you where a box can't go, without giving the board away. ALSO • An optional daily reminder at the time you choose. • Stats with a calendar of your solves, by week, month or all time. • English and Arabic, light and dark, colour-blind patterns, haptics. • No account and no sign-in. Your progress stays on your iPhone. Boxed is free and supported by ads: a banner on the menus, an ad between some puzzles, and an optional ad you can watch for a hint. Ads never appear while you're solving. A one-time "Remove ads" purchase removes the banner and the ads between puzzles, and makes hints free. Questions or ideas: zaplatform@gmail.com
