About

Kinsei

Features
Read full description

Kinsei is a logic puzzle built around balance. Each puzzle gives you a grid with totals along the edges. Your goal is simple: fill the open cells so every row and column adds up exactly. Numbers may repeat. Empty playable cells must be solved. Every puzzle has one solution. The result is a puzzle that feels familiar if you love Sudoku, but plays by its own rules. Kinsei is not about speed or guessing. It is about careful reasoning, elegant deductions, and the satisfying moment when the whole board clicks into balance. HOW IT WORKS Fill each open cell with a number from the allowed range. Match every row total. Match every column total. Use notes to track possibilities. Solve through logic, not guessing. A NEW SKILL LADDER Kinsei is designed to grow with you. Start with approachable 5x5 puzzles that teach the basics, then build toward larger 7x7 and 9x9 boards that require deeper strategy. As you improve, you will learn named techniques such as hidden singles, over-under balance, line budget locks, crossing pairs, subtotal windows, forced partitions, parity webs, and advanced master-level patterns. The goal is not just to solve more puzzles. It is to become a stronger solver. WHATโ€™S INCLUDED Daily Puzzle shared by all players Beginner-friendly onboarding puzzles 5x5, 7x7, and 9x9 puzzle packs Difficulty levels from beginner to esoteric Hint system that teaches named techniques Check feature to review your current board Infinite undo Pencil notes Pauseable timer Post-solve recaps Player statistics and achievements Shareable completion results Practice generator included with Kinsei Complete LEARN MODE Browse techniques, study examples, and practice individual skills.
