Elites: Grid Lrdi 2023 Matrix Arrangement Lesson...

She checks the original text: Clue 6 actually says: (E1, E2): Same number. That’s impossible under standard rules. So either it’s a trick — meaning E1 and E2 are the same number, so the row has a duplicate, meaning the “each row has 1..5 once” rule is for numbers? Or the puzzle uses numbers 1-5 with repetition allowed? But that breaks Latin square.

We need a systematic solve, but in story form, Riya realizes: “The star Latin square is the key. Let’s assume star positions.” She checks the original text: Clue 6 actually

Clue 9: C1+D1=7.

And that, dear reader, is how you master the Elites Grid LRDI 2023 Matrix Arrangement. Or the puzzle uses numbers 1-5 with repetition allowed

That fixes it. Now E1 and E2 share a symbol, say S_E. E4 and E5 differ by 2 in number.
