Rules
- Your 5×5 card has five columns: B uses 1–15, I 16–30, N 31–45, G 46–60 and O 61–75. The center is free. Every call comes from a shuffled sequence without repeats.
- Call numbers manually or turn on one call every three seconds. Select a called number on your card to mark it. An uncalled number cannot be marked; selecting a marked number removes its mark.
- Complete a horizontal, vertical or diagonal line, then press Confirm Bingo. A line is not claimed automatically. Relaxed mode allows all 75 calls. Challenge mode stops at 40; if no full line has been called, the round ends. If a line is available, mark and claim it.
- Leaving the tab stops automatic calls. Use Tab and arrows to navigate and Enter to mark. Undo restores the previous action; hints and undo mark the result as assisted. The daily challenge uses the same card and call order across languages. There is no money, betting or prize.

Strategy
Keep an eye on the free center, which belongs to the middle row, middle column and both diagonals. Those lines need only four called numbers.
