You do not need to know everything to start. Here you will find carefully explained rules, clear examples, and an idea or two for your next game.

Peg solitaire: prepare your next jump

One fewer peg does not always mean a better position. Keep useful connections and explore a worked solution whenever you want.

One square has two values: one for its row and another for its column. Understanding that difference is the first step towards solving the grid.

Taking the most does not always win. Understand the ending first, then decide which position to leave your opponent.

A grid of zeros and ones is solved through balance, limits and differences. No arithmetic operations are needed.
