CoreShift is a sleek, minimalist strategy game based on Neutron — a classic abstract board game of pure skill, positioning, and tactics. Easy to learn. Deep to master. Every move can open a path, create a trap, or turn the match completely. No randomness. No hidden information. Pure strategy. THE GAME Play on a 5×5 grid. Each player controls five pieces, while a single amber token — the Neutron — begins at the center. On every turn, you must: 1. Slide the Neutron as far as it can move. 2. Slide one of your own pieces (horizontal, vertical, or diagonal). Pieces move until blocked by the edge or another piece — they cannot jump. How to win: * Move the Neutron onto your own baseline. * Trap your opponent so they have no legal Neutron move. QUICK OR CLASSIC * Quick mode: Fast, aggressive openings with immediate tension. * Classic mode: Traditional rules where the first player skips the opening Neutron move for a more balanced start. THREE AI DIFFICULTY LEVELS * Easy: Learn the fundamentals. * Medium: Strong tactical play. * Hard: Advanced Monte Carlo Tree Search (MCTS) AI that adapts to every position.
