Siege vs CoreShift

Siege is a 3D abstract strategy board game designed for calm, focused play. Place cubes on a grid, stack them with gravity, and capture your opponent's pieces by surrounding them on all four sides. Captured cubes are removed from the board — pieces above fall down, triggering cascading chain reactions. Every exterior face of your cubes scores points, including ground-level faces. The player with the most points wins. Like Go in three dimensions.

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.
