A long CON or big con (also, chiefly British English: long game)[4] is a scam that unfolds over several days or weeks and involves a team of swindlers, as well as props, sets, extras, costumes, and scripted lines. It aims to rob the victim of huge sums of money or valuable things, often by getting him or her to empty out banking accounts and borrow from family members.
