Pitch / Prototype
Surround the King without breaking the board.
A two-player strategy prototype played on one shared, connected board.
You and your opponent build on the same board as you play. Add and move pieces with distinct rules, keep the board connected, and try to occupy all six spaces around the opposing King.
Prototype · iOS and macOS development builds · Not publicly released
A board that grows, where each piece redraws what is possible.
There is one pitch and it belongs to both of you, so every legal move has to leave it as a single connected whole.
Build
Set a new piece against the edge of the connected pitch and open routes that were not there a turn ago.
Reposition
Move a piece by its own rule, making sure the entire pitch stays connected in one piece afterward.
Surround
Fill every one of the six spaces around your opponent's King, and the game is yours.
What it taught us
Teaching the computer the rules was only the beginning.
Building Pitch's computer player meant turning a human sense of position into testable decisions: generating only legal moves, recognizing threats around the King, evaluating incomplete positions, and searching as deeply as a fixed thinking-time budget allows. It was a useful lesson in how quickly a compact rule set can create a large decision space.
