Planning collection

Strategy Games with Visible Decisions and Replayable States

Strategy becomes easier to study when the rules are deterministic and the position can be replayed. The games in this collection expose different planning horizons: a few tactical moves in a board game, a full visible deck in FreeCell, or a candidate chain across Sudoku.

Plan with capacity

FreeCell, Baker's Game, and Eight Off turn empty cells and columns into move capacity. Counting that space before lifting a sequence prevents a legal first step from ending in an immovable stack.

Plan with threats

Connect Four asks whether a drop creates or supports two future lines; Tic-Tac-Toe compresses the same idea into forks. Deterministic local opponents first take wins and block immediate losses, making unsupported threats easy to test.

Plan with state transitions

In 2048, every directional input compresses and merges the whole board before a new tile appears. In Sudoku, one placement removes candidates from three units. Predicting the complete state change is more reliable than following one attractive piece.

Questions about this collection

Which games show all information from the start?

FreeCell, Baker's Game, Eight Off, Sudoku, Tic-Tac-Toe, and Connect Four expose the decision state; generated future responses may still occur after moves.

What is a replayable state?

A numbered or dated seed recreates the same starting layout under the same rules version, allowing another move order to be compared.

Are local opponents adaptive?

No. The board opponents use documented deterministic priorities and do not profile the player or send moves to a server.
