A crossword made of numbers. Fill every sandstone square with a number from 1 to 9.
No number can repeat within one run. Tip: small and big totals have few options. 3 in two squares can only be 1 + 2!
Tap a square, then a number. Use NOTES to pencil in possibilities. {{helpTip}}
Every tomb has exactly one answer. A new tomb opens every day at midnight.
