Fill the grid. Obey every bond.
Every row and column holds each number once, like a Latin square. The lines between nodes carry bonds: one number is greater, the gap is exactly two, the pair sums to a prime, and more. Each chapter teaches a new kind of bond. Planning and pencil marks are always free; a try is spent only when you check a wrong grid.
