ORBIS — A CIRCLE SUDOKU THAT'S GENUINELY DIFFERENT
Place numbers 1–9 in a 3×3 grid. Each amber circle sits where four cells
meet — and its number must equal the SUM of those four cells.
Simple rule. Surprisingly deep puzzles. No two levels solved the same way.

🎯 HOW TO PLAY
Every circle = the sum of its 4 surrounding cells. Work out which numbers
fit by testing combinations against the circle totals. Use the Hint
