Step 1 of 7
Two chains, one digit. Simple Coloring works on a single strong-link chain. Multi-Coloring uses TWO independent chains on the same digit. Each chain has its own A/B coloring. Cross-chain interactions — when a color in chain 1 sees a color in chain 2 — produce eliminations beyond either chain alone.
