Master the Geometry of Logic. Step into the world of Shikaku (also known as Rectangles), a classic Japanese logic puzzle reimagined for the modern era. Shikaku is a minimalist experience designed for those who find beauty in structure and peace in problem-solving. THE GOAL Divide the grid into rectangular and square pieces such that each piece contains exactly one number. That number must represent the total area (the number of cells) of that rectangle. It’s simple to learn, but mastery requires a deep understanding of logical geometry. WHY PLAY SHIKAKU? • Handcrafted Minimalism: A clean, distraction-free interface that lets you focus entirely on the puzzle at hand. • Daily Chapters: Every day brings a new "Chapter" with three stages of escalating difficulty. Start your morning with a light challenge and end your day with a masterclass in logic. • Infinite Endless Mode: Never run out of puzzles. Generate grids of various sizes—from quick 4x4 warm-ups to daunting large-scale grids. • Personalize Your Experience: Express yourself with over 16 vibrant themes, including Tokyo Neon, Sakura, Botanical, and Midnight. • Mastery XP System: Prove your skill. Turn off assistive features to earn 1.5x XP and climb the ranks of logic masters. • Zero Distractions: No ads. No interruptions. Just you and the grid. Whether you’re a Sudoku veteran or a casual puzzle lover, Shikaku offers a meditative yet mentally stimulating escape. Handcrafted with pride by De Groot Studio.

Verdict

The call

The clearest difference is in-app purchases: Shikaku at none against One Color!'s 7. Shikaku also leads on review sentiment (76% vs 44%). One Color!'s advantage is rating (4.7 vs 4.4) and update cadence (every 4 days vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

One Color! holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: One Color! has 249 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 76% of Shikaku's written reviews are positive against 44% of One Color!'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Shikaku ships an update every 3 weeks, One Color! every 4 days. The most recent releases landed on October 31, 2026 and November 5, 2026 respectively.
