## What is Zenkuro?

Zenkuro is a calm, pastel take on Kakuro — the classic "cross sums" number puzzle. Settle into a quiet grid, fill each run of cells so it adds up to its clue using the digits 1 to 9 with no repeats, and let the numbers fall into place.

Every puzzle is generated on the spot with a guaranteed unique solution — no databases, no repeats, just an endless supply of fresh grids across several difficulty levels.

WHY YOU'LL LOVE IT
• Soft pastel, zen design made for relaxing
• Endless randomly generated puzzles, each with one unique solution
• Multiple difficulty levels, from a gentle warm-up to a real brain workout
• Pencil mode to jot candidate digits in each cell
• Hints when you're stuck, and unlimited undo
• Built-in timer and best-time tracking per difficulty
• Auto-save: leave anytime and resume right where you left off
• Haptic and sound feedback for input, mistakes and victories
• Full English and French support
• No forced ads: they stay optional, and removable with a single purchase

HOW TO PLAY
Kakuro is like a crossword with numbers. Each clue tells you the sum of the cells in its row or column. Fill them with the digits 1 to 9 so they reach the sum — and never repeat a digit within the same run. New to it? A gentle in-app tutorial walks you through the rules.

Breathe, think, solve. Welcome to Zenkuro.
