Scam #31: Chip Capping on Winning Bets

How it works

After the ball has landed on a winning number, the cheater uses sleight of hand to add additional chips to their existing winning bet. Unlike classic past posting (placing a new bet on a number where there was no bet), chip capping increases the value of a bet that was already placed before the spin. The cheater may palm additional chips and drop them onto their winning stack while the dealer’s attention is on the wheel. Alternatively, the cheater may use a “kick” technique — resting their hand on the layout with a chip hidden underneath, then using an imperceptible thumb snap to slide the chip across the baize onto the winning bet. The move is covered by a partner leaning over the table to “get a better look” at the result, blocking the dealer’s and cameras’ view of the capping action.

On the record

Chip capping is one of the most fundamental sleight-of-hand techniques in gambling fraud. It has been practiced since at least the early 20th century and remains common today. Professional mechanics practice the “kick” move thousands of times on a practice layout before attempting it in a casino.
