Read a clue. Cross off what it rules out. Watch the consequences ripple until one arrangement survives. Zebra is a logic-grid game — the classic "the doctor lives in the red house" puzzle — built around a generator that proves every board before it reaches you. There is exactly one solution, it is always reachable by reasoning, and you are never asked to guess. TIERS THAT NAME THE TECHNIQUE Four difficulty tiers, each named after the reasoning it asks for rather than a vague star rating: cross off, chain, work out before-and-after, test a possibility. The generator computes the exact deduction depth each case requires, so the label is measured, not asserted.
