Board Game With 50-Point "Bingo" Bonus: It's Bingo Itself

Bingo itself.

In standard North American 75-ball Bingo:

• Cards: 5×5 grid, columns B-I-N-G-O (1–15, 16–30, 31–45, 46–60, 61–75), center FREE.
• Caller draws balls (B-7, N-33, etc.).
• Players mark matching numbers.
• First to complete a pattern (line, four corners, blackout) shouts "BINGO!"
• Verified winner gets prize/points.

The 50-point bonus is a common house rule / tournament scoring value for a "Bingo" (completed pattern), distinct from the game name. Some variants:

• Line = 10 pts, Two lines = 25, Full house = 50.
• Progressive: each game adds to jackpot.
• Speed Bingo: fewer balls, higher points.

No other mainstream board game uses "Bingo" as a 50-point bonus term. The phrase is synonymous with the game itself.
