Rysiek: IO Play

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

📖 The story behind the game
When I was 13 years old 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 a WIN can be calculated purely mathematically. This concept completely intrigued me, and I promised myself that one day I would write such a game as a computer program. The game RYSIEK is the result of that childhood dream!

🧠 How to play (rules of the game)
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 of any single button by any amount.

Press the "Rysiek" button to pass the turn to your opponent.

Keep playing.

🏆 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 ending your turn!)

⚙️ Game modes and customization
To keep your brain constantly on its toes, 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): Random starting values for highly unpredictable gameplay.

Adjustable board size: Choose the number of buttons on the board (from 3 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 on your commute or want to dive into a deep strategic session to uncover the mathematical secret to winning, this app is the perfect companion. It’s a great brain teaser for adults and an excellent educational logic puzzle for students.
