Elevens Console Game (C#)

Project Overview

This project is a console-based implementation of the Elevens card game, written in C# using object-oriented programming principles. Elevens is a single-player solitaire-style game where the player removes cards from a 9-card board by forming valid combinations until the game is either won or no valid moves remain.

Game Rules

The game is played using a standard 52-card deck.

Valid Moves

The player may remove cards from the board using one of the following rules:

1. Two-card move

   • Select two cards whose values sum to 11
   • Card values:
     • Ace = 1
     • Cards 2–10 = face value
     • Jack, Queen, King = 0 (not used in pairs)

2. Three-card move (Face cards)

   • Select one Jack, one Queen, and one King (any suits)

Win Condition

• The player wins when:
  • All cards on the board are removed
  • The deck has no cards remaining

Lose Condition

• The player loses when:
  • No valid moves remain on the board
  • This can occur even if cards are still left in the deck
