Gravity Grid

Gravity Grid is a two-player strategy game that blends the falling block mechanics of Tetris with the classic three in a row goal of Tic Tac Toe. Instead of placing simple marks, players drop mini-Tetris style shapes into a tall 3×6 grid, obeying gravity as the pieces fall and stack from the bottom up.

Each turn, you choose one of four allowed shapes — a single block, a 2-block line, an L-shape, or a 2×2 square — and drop it into a column. Every square you place belongs to you, and you’re racing to connect three of your own squares in a row: horizontally, vertically, or diagonally.

The twist? The board is tiny and fills up fast. Big shapes give you power, but they also clog the grid and can trap you later. If you ever reach a turn where no legal shape fits, you lose by overflow.

This game is simple to set up, surprisingly deep, and perfect for quick matches, experiments, and strategy battles.
