Are you ready for a true mathematical and logical challenge? Meet Rysiek, your new virtual opponent in a game where strategy, planning, and foresight are the keys to victory!

📖 The Story Behind the Game
When I was 13 and in the sixth grade, my math teacher gave me a book of logic puzzles. Inside, I found an incredibly interesting game. It was described as a puzzle where the WIN could be calculated entirely mathematically. That concept completely intrigued me, and I promised myself that I would write such a game as a computer program someday. The game RYSIEK is the result of that childhood dream!

🧠 How to Play (Game Rules)
The rules are simple to learn, but mastering the game requires sharp thinking:
Decide who starts the game – You or Rysiek.
On your turn, decrease the value on any single button by any amount you choose.
Press the "Rysiek" button to pass the turn to your opponent.

Continue taking turns.
🏆 THE PLAYER WHO MAKES THE LAST MOVE WINS!

(Note: You can only change the value of one button per turn, and you must make a move before passing the turn!)

⚙️ Game Modes & Customization
To keep your brain constantly engaged, the app offers multiple game variants and settings:
Classic (1..N): Standard sequential starting values.
Unique (1..N / 1..24): Distinct, non-repeating values for a balanced challenge.
Random (1..N / 1..24): Randomized starting values for highly unpredictable gameplay.

Adjustable Board Size: Choose the number of buttons on the board (from 3 up to 24) to scale the difficulty. The more buttons you add, the more complex the mathematical combinations become!

💡 Why play Rysiek?
Whether you want a quick mental workout during a commute or a deep strategic session to crack the mathematical secret of winning, this app is the perfect companion. It is a great brain-teaser for adults and an excellent educational logic puzzle for students.
