Puzzle 2: Icy Inversion 🧊
This triangle points up (like a mountain 🗻)
What is the least number of snowflakes which must be moved so that the triangle points down (like this pizza slice 🍕)?
Vote below and reply with your pics & reasoning — we’d love to see your ideas! 🧠👇

Been enjoying our National Puzzle Day posts so far? Here’s the final puzzle — and it’s a tough one! 🌰
In fact, this one’s a specimen exam question from one of our most popular modules MST368: Graphs, Games & Designs (sorry not sorry)

💡 You could also try the substitution method.
We’ve seen some savvy solvers already crack it — what method did you use? Share your approach below!
Good luck, and happy puzzling! 🍀

How’s it going with our #NationalPuzzleDay puzzles? Need a hint for Puzzle 1: Frosty Equations? 🥶
1️⃣ Subtract equation 3 from equation 2 — this is called the elimination method. You’ll discover that 🥊 = 3.
2️⃣ Consider equation 1…how might knowing 🥊 = 3 help?

2️⃣ Pro tip: Sketch the triangle using different colours for each row or use coloured counters to make a moveable version. It’ll make tracking your moves much easier! 🎨
Good luck, and happy puzzling! 🍀 #NationalPuzzleDay

Yesterday, we shared a hint for Puzzle 1: Frosty Equations. Today, let’s tackle Puzzle 2: Icy Inversion! 🧊💡
1️⃣ Focus on the vertices — a single move here has the biggest impact on the triangle’s orientation. Check out a (possible) first move below 👇🏻
