Grid Game

• Name: Rishit Nanda
• Roll No: 2025111008

Simple interactive terminal grid game in C. Players place colored dots on a 24×24 board.

• RED: even turns (0, 2, 4, ...)
• BLUE: odd turns (1, 3, 5, ...)

Board & Coordinates

• Board size: 24 × 24
• Rows and columns are numbered 1-24 (enter coordinates in that range)
• Enter -1 -1 to quit

Movement restrictions

• RED cannot place on columns 1 or 24.
• BLUE cannot place on rows 1 or 24.
• A move is invalid if:
  • It's outside 1-24
  • The cell is already occupied
  • It violates the color-specific restriction

Gameplay

• Players alternate placing colored dots on the board
• When a dot is placed, the game automatically creates edges (connections) to adjacent dots of the same color
• Adjacent means knight's move distance (like in chess: 2 squares in one direction, 1 square perpendicular)
• Edges cannot cross each other - if a potential edge would intersect an existing edge, it won't be created
• RED wins by creating a connected path from row 1 to row 24 (1/2-23/24 also works as its trivial that blue's path is now blocked)
• BLUE wins by creating a connected path from column 1 to column 24 (1/2-23/24 also works as its trivial that red's path is now blocked)
• A connected path means dots linked by edges, allowing you to traverse from one winning zone to the other
