Color Chain Reactor

Placement: Players take turns placing a piece of their color onto any empty cell on the grid.

Chaining: When you place a piece, you score points for every piece of the same color that is directly adjacent (up, down, left, right).

The Reactor Rule (The Twist!):

• If you place a piece and it completes a line of three or more pieces of the same color (horizontally or vertically), those three (or more) pieces vanish from the board, giving you bonus points and freeing up space.
• Any piece that vanishes can potentially chain into another vanishing line if it was part of a different color line of three. (This is the "Reactor" effect).

Endgame: The game ends when the board is completely full. The player with the highest score wins.
