Round 7 of 16

Prime Points & Corners

📋 What it is

The four cross-junctions connect four lines each — the most valuable points; corners connect only two.

🗣️ Coach says

Not all points are equal. The four "T" junctions (mid-edge cross-points) sit on FOUR lines, so a piece there can help make four different mills. Corners touch only TWO lines, so they're weaker. Fighting for the junctions early is a proven way to get the upper hand.

🧠 Memory hook

Junctions touch four lines (strong). Corners touch two (weak). Grab the junctions.

😂 Giggle

Why did the piece feel trapped?
All its neighbouring points were taken — no legal move means the game's nearly up!

😲 Whoa!

Controlling the four junction points is so strong that many opening guides say "take the crosses first" — it's the mill game's version of grabbing the centre in chess.

✅ Quick check: Why are the four cross-junction points more valuable than the corners?

Say your answer out loud first — then reveal.

🧪 Try it! (2 minutes)

Count how many lines pass through a junction (4) versus a corner (2). Prioritise the junctions.
