Bingodoku is a fun combination of Bingo and Sudoku!
Rules 1 to 4 are standard bingo rules:
1. Complete the strip of six bingo tickets so that numbers 1-90 appear exactly once.
2. Numbers appear in columns (1–9, 10–19, 20–29, 30–39, 40–49, 50–59, 60–69, 70–79, 80–90).
3. On each ticket the numbers in a column are in ascending order (reading top to bottom).
4. Each line contains five numbers and four blanks (shaded).
Rule 5 adds an extra Sudoku twist:
5. No two numbers on a line have a common digit.
Solution code: row two (five two-digit numbers, no spaces)
