Capy Doku: Queens Puzzle
A calm, unhurried logic puzzle
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
One board at a time, no rush. A new challenge every day.
Capy Doku is a Queens-style logic puzzle with a capybara who's in no hurry at all.
The rule is simple: place one capybara in every row, every column and every colored region. Two capybaras never touch, not even diagonally. Every board has a single solution and can be solved with logic alone, no guessing.
• 300 levels, from 4×4 to 10×10, across four difficulties
• Daily challenge: a fresh board every morning, with day streaks
• Hints that explain the reasoning, not just the answer
• Mistakes pointed out gently: no drama
• Tap to mark ×, tap twice for a capybara, drag to mark many cells
• Collect outfits for Capy with the leaves you earn by playing
• Board themes, dark mode and colorblind patterns
Capy Pro (optional): no ads, unlimited hints and every theme. Monthly or yearly subscription, or a one-time lifetime purchase.
One board at a time. No rush.
The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel it in your Apple ID settings.
