Bingo Caller Override

宾果（Bingo）已报道技巧等级：Professional

工作原理

The caller is supposed to announce the numbers a random draw has produced. The cheat is the caller turning that draw off and announcing numbers he already knows are on a confederate’s card. The game looks normal from the floor. The randomness was switched off.

出现场合

Bingo halls, including bingo run by a casino

有据可查

The Chronicle Live of 27 February 2013 reported that Newcastle Crown Court jailed Christian Grant for nine months. He was a caller at Gala Bingo in Sunderland. He overrode the random draw. Two women with him won £7,830 and £1,040. All three admitted conspiracy to defraud.
