Parity Twist — A 2-player strategy game on a 3×3 grid.

Setup: The grid has 3 columns — one for each player and a Key column — plus a Master Key cell below the Key column.

How to play:

Players take turns placing numbers 1–10 into any empty cell (including the opponent's column, Key, or Master Key)
Each number can only be used once
The game ends when all 10 cells are filled

Scoring: For each row, compare the Key number's parity (odd/even) to the Master Key's parity:

Same parity (both odd or both even) → the lower number between P1 and P2 wins the row
Different parity → the higher number wins the row

Winning: Win 2 out of 3 rows to win the game!
