Sekisho Building is a new building-height logic puzzle with hint cells placed inside the grid instead of around it. ■ Solve with logic, not luck No guessing required, ever. Every puzzle is solvable by stacking simple, deterministic techniques until you reach the one true answer. ■ Difficulty that adjusts to you Your rating shifts as you play, and each new puzzle is freshly generated to match it. There's no fixed puzzle set, so you'll always find something new. ■ Input that feels effortless Long-press to enter a number, double-tap to jot a note. Every interaction is tuned for comfortable one-handed play. ■ Learn techniques, step by step Built-in lessons cover everything from the basics to advanced techniques. When you're stuck, work through a lesson to pick up the idea one step at a time. ■ Light or dark, your choice Follow your system setting or pick your favorite palette. Dark mode is easy on the eyes for late-night solving. One quick puzzle between tasks, or one deep session when you have the time — there's always a puzzle that fits your skill, waiting right here.
