Greater Than Sudoku Cache Builder
Make your own daily Greater Than Sudoku geocache with a sharable play link.
Greater Than Sudoku (also called Comparison Sudoku) is a 9 by 9 Sudoku with no starting numbers. Instead, a greater-than or less-than sign sits between neighbouring cells inside each box, always pointing at the larger digit, and the signs alone pin the whole grid down. A brand new puzzle is generated on the server every day, the same for everyone, and solving that day's puzzle reveals your final coordinates or keyword. The answer is never hidden in the page, so there is nothing to peek at.
Save this link now. Without the key you cannot edit or delete this puzzle (only the site admin can reset it).

Keep your cache in play to keep it live. Share the play link so people visit it; unused caches are cleaned up over time.
