ALERT!: Entering some wrong answers will end the quiz
Every number is used once. Adjacent includes diagonals. 1 is not considered a prime number. Can be solved without guessing!
For numbers 1-9, this quiz accepts both single-digit numbers and 01, 02, etc. Single-digit 1 and 2 don't set off mines for cells where two-digit numbers are required (so in those cells, starting to type 16 or 22 doesn't set off mines).
