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.

The same board for everyone, every day. One attempt. How far you push it is up to you. SAPPER is minesweeper with no edges. Each day the world gets one shared minefield, identical for every player. Start on safe ground and sweep outward. The farther you go, the denser the mines and the more every safe tile is worth. A Cash Out button sits on screen the whole time. Bank your score, or push one more row into the unknown. Hit a mine and the run ends with half of what you had not banked. Cash out and all of it is yours. That choice is the whole game. Then see how your run stacks up and share the shape of the territory you cleared. Miss a day and it is gone. Tomorrow there is a new board, the same for everyone, again. MORE WAYS TO PLAY Endless: a fresh board every run, whenever you want. Chase your personal best. Rush: two minutes on the clock. Clearing tiles buys time, mines cost it, and there is no Cash Out. How long you last is the score. The Daily is free for everyone, forever. One single purchase unlocks the full game, Endless and Rush included, for good. Your first day comes fully unlocked, so you know exactly what you are buying. No subscriptions. EVERY CASH-OUT LEAVES A MARK Cash out on purpose and the expedition is preserved in the Archive: the shape of the territory you cleared, the score, how far you pushed.
