Wayo for Roulette
Di first roulette wheels wey get wayo na di house own am. Today, wayo dey happen for di layout, often wit help from dealer, and dem build every table wey get licence to catch am.
Pipo wey dey do wayo for roulette don attack four tins: di wheel, wey dem build to direct di ball; di bet, wey dem change afta di result; di dealer, wey dem pay to help; and di software, wey dem change make e pay. Di gaffed wheel na di tool of di house for illegal gambling houses of di 19th and early 20th centuries; casinos wey get licence now dey check every wheel for magnets before table open. Late bets, wey corrupt dealer dey often take, na wetin courts dey see today. To read biased wheel or ball wey you fit predict wit your eye no be wayo; to use device to do am na crime for Nevada.
Two different tins
Advantage play dey use information wey anybody fit gather, one biased wheellabBiased wheelWheel wey get physical defect wey make some pockets come out pass 1/37. E rare, and you fit only find am with thousands of spins wey you record.Read di whole tin → or ballequipmentBallDi small ball wey dem dey throw for di track against di rotor. Modern balls na ivorine or Teflon, 18–21 mm.Read di whole tin → wey you fit predict, and e dey bet on am before betting close. Wayo for roulette dey change di game: e dey add to bet afta pipo don sabi di result, e dey take back bet wey lose, or e dey hide how much person bet. Di first one dey usually legal, and di answer of di casino na to fix di wheel or ban di player. Di second one na fraud. For Nevada, to put or change bet once di outcome don dey known na offence by imself. Police arrest di Ritz players of 2004, release dem, and give dem dia moni back when dem drop di case; dem dey prosecute past-posters.
Four ways to do wayo for roulette
Pipo fit attack fair spin for four points: di wheel imself, di bet once di result don dey known, di dealer wey dey settle di bets, and, for machines and online, di software wey dey pay dem. Who dey do di wayo don change wit time. For di 19th century, na mostly di house. Today na mostly players, often wit help from dealer.
Di roulette wheel wey get wayo, 1890 reach di 1930s
For im first century for America, di person wey no dey honest for roulette table na usually di house. John Philip Quinn, one gambler wey don change, describe di devices for 1890. One lever under di wheel dey work through one leg of di table, wey dem make short small pass di oda ones, so di dealer wey lean on am go change di direction of di ball from redbetRedEven-money bet on di 18 red numbers. For French: rouge.Read di whole tin → to blackbetBlackEven-money bet for di 18 black numbers. For French: noir.Read di whole tin →. For anoda wheel, half of di fretsequipmentFretDi metal wey divide two pockets for di wheel.Read di whole tin →, di metal dividers between di pocketsequipmentPocketOne of di 37 small boxes wey get number for di rotor. Dem also dey call am: slot, cup.Read di whole tin →, tall small pass: becos di colours dey alternate, to spin di ball one way or di oda go favour red or black, and di dealer go choose di colour wey get less moni. Di third one get false centre where rods dey push small needle points up for front of alternate pockets. Quinn print again di catalogue of one New York supplier wey dey offer wheels “wey dem fit make come Red or Black, or High or Low Number, exactly as di dealer want.” By 1912 e write sey electricity na di method wey popular, wit wires wey dem run up one leg of di table from battery for di cellar, and e suggest pocket compass to find am: di needle dey shake when di current dey on. Di National Museum of American History of di Smithsonian get one magnetic roulette wheel of di 1930s wey dem make for Chicago: di dealer dey on im electromagnet wit button to push di ball away from numbers wey get big bets.
Why e hard to rig wheel wey get licence
Di gaffed wheel na for houses wey no get regulator. For casino wey get licence, di controls dey inside di rules. Di rules of New Jersey na example: before table open, dem go check di wheel for magnets and any oda device, for level, and sey e dey turn free and even; dem go pass di ball over magnet or compass, and e must no get any metal at all; dem dey write down every adjustment, and locked cover dey go on di wheel when di table close. Plenty modern wheels dey read di winning number wit sensors for di rim and send every result to di casino software, so wheel wey dey favour some numbers go show for di house own statistics. Di house no get reason to take di risk too. Fair single-zerowheelZeroDi one green pocket wey no even-money, dozen or column bet dey cover; na im be di source of di house edge. Dem also dey call am: single zero, 0.Read di whole tin → wheel dey keep 2.70% of everytin wey pipo bet, and wheel wey dem rig go cost di licence.
Past-posting
Di classic roulette scam na past-posting: to slip chipmoniChipToken wey stand for one fixed amount, wey you put on top di layout to make bet. Dem also dey call am: check.Read di whole tin → on top, or under, one winning bet afta di ball don drop, den claim di payoutmoniPayoutWetin bet wey win dey return, wey dem dey quote as “X to 1” on top di stake wey dem return.Read di whole tin →. E need team. One mechanic dey make di move while di dealer dey busy, one claimer wey di dealer never see dey collect, and one lookout dey watch di pit and cancel di play wit hand signal. Di moment na di payout imself, when di dealer turn to bring chips for outside winner and nobody dey watch di inside numbers for few seconds.
Richard Marcus
Marcus na dealer for di Four Queens for Las Vegas for di 1970s when one past-posting crew recruit am. As e tok am, e work wit dem, den e lead im own team, for about 25 years for roulette, craps and blackjack, and e stop around 2000 without any court wey find am guilty. Im memoir of 2003 describe di roulette version. Two players dey cover di third dozenbetDozen1–12, 13–24 or 25–36, e dey pay 2:1.Read di whole tin →, chip by chip, spin afta spin, until e hit; while di dealer dey pay di dozen, one hand go slide $100 chip under one winning straight-up stack. Di claimer don already make one real $100 straight-up bet, so di pit remember am as player of dat size, and di move worth $3,500. To keep di layoutequipmentLayoutDi betting grid wey dem print for di table. Dem also dey call am: table, felt, cloth.Read di whole tin → busy cost di team only di house edgemathsHouse edgeDi part of each stake wey di casino dey keep for average: 2.70% for European roulette.Read di whole tin → on im cover bets.
Di Savannah
Di move wey make Marcus popular pass no be past-post at all. Before di spin, e put $5 chip on top $5,000 chip on one outside betbetOutside betBet on di boxes wey surround di grid: dozens, columns and even-money bets.Read di whole tin →, wit di big chip push back so di dealer see only small stack. If di bet win, di dealer go find di big chip and pay am: $5,005 on red, $10,010 on one dozen. If e lose, Marcus go lift di stack before di sweep, and if anybody challenge am, e go put down two $5 chips wey e don hide for palm before; di dealer, wey read di bet as $10, no see anytin wrong. Every winning bet na real, and every losing one disappear. Later accounts give am credit for about $5 million before casinos stop to pay am.
Work from inside
Most roulette wayo wey reach court now involve dealer. Di usual method na late bet: di dealer allow partner to put or add to bet afta di ball don drop, or e release di ball early so bet go enter before electronic cut-off. Di sums no dey usually big, and di cases dey usually come out through di camera wey dey over every table, or through one player wey dey always win for di table of one dealer.
Di machines and di software
Electronic roulette dey move di target from di chips go di code. For di summer of 2007, two IT contractors for one London casino group change im system so di terminals for live roulette tables dey print winning slips, wey worth reach £600 each, whatever number show. Dem cash about £33,000 for four casinos, plead guilty to theft and collect suspended sentences for 2010. Online, di risk for player na operator wey no get licence, wey nobody dey test im software. For games wey get licence, we no find any regulator finding of roulette generator wey dem rig. Wetin dey reach di courts na malfunctions: for 2021 BetMGM cancel di run of one Michigan player from $50 reach about $3.3 million for one online roulette game as software error, and for 2025 di Supreme Court of di state allow her case to continue. Error wey di casino refuse to pay na argument about contract, no be proof sey dem rig di game.
Devices, and where di law draw di line
To predict di ball no be wayo by imself. To read biased wheel, as Joseph Jagger and di García-Pelayo family do, dey use information wey anybody fit collect. Di Supreme Court of Spain rule for 2004 sey di García-Pelayos use sense and computer, no be wayo, and sey di remedy of di casino na to change im wheels. To carry di computer go di table na different matter. Nevada don make am crime to use or hold any device wey dem design to predict di outcome of game or analyse im probabilities, and e don treat am as felony since 1985. Di Gambling Act 2005 of Britain make cheating offence and e tok sey e fit be interference wit di process of di game; for 2017 di UK Supreme Court hold, for Ivey v Genting, sey cheating no need to be dishonest.

Stories wey every wayo article dey repeat
Two stories dey show for page afta page about roulette wayo pipo, and nobody fit trace any of dem to source. Pierre Dugal, one Frenchman wey dem tok sey rig wheels for di early 19th century and im wife betray am, dey show wit no date, no casino and no trial. Monique Laurent, wey dem tok sey direct one ball wey radio dey control from transmitter wey she hide inside cigarette packet for di 1970s, dey show for versions wey no agree on di casino, di amount, “5 million francs” or “$1 million”, and weda police ever arrest her. We no find any newspaper, court record or book of dat time for any of dem. Two oda claims dey wrong clear clear: di case of García-Pelayo na for Spain dem decide am, no be di United States Supreme Court, and Richard Marcus, as e tok am and later interviews, no court ever find am guilty.
How di casino dey catch am
Most of di routine of dealer na protection against di chip moves wey dey up. “No more betsprocedureNo more betsDi call of di dealer (or di prompt for screen) wey dey close betting. Nobody fit put, move or remove chips again.Read di whole tin →” dey close di layout before di ball drop. Di dollyequipmentDollyDi marker wey dem put on top di number wey win for di layout while dem dey settle di bets.Read di whole tin → dey mark di winning number, and notin for di felt fit move while e dey down. Dem dey sweep losing chips before dem pay any winner, so nobody fit take back losing bet during di payout. Dealer wey see chip wey get high value for di layout go call am out to di pit, and na why di claimer of Marcus first put im real big bet. Colour chipstableColour chipsChips wey na only for roulette, each player for di table get im own colour, with value wey you set when you buy in. Dem also dey call dem: wheel checks.Read di whole tin →, one colour for each player, dey make chip of stranger stand out, and cameras for up dey record every payout to check later. Di rest of di casino dey cover di oda methods.
Wetin e mean for ordinary player
For casino wey get licence, di gaffed wheel na history, and di wayo pipo for di table dey rob di casino, no be di players wey dey near dem. No legal move for di table fit beat fair wheel, and notin wey roulette wayo person dey do fit change di odds for anybody else. Two habits go keep player far from suspicion. Leave your chips alone while di dolly dey down, even di ones wey win, becos to reach for dem dat time look exactly like di move wey di cameras dey there to catch. And refuse any dealer wey offer to help, becos late bet wey dem take as favour na di same crime as one wey dem buy. Online, play only where you fit check di licence of di operator wit di regulator. Game wey no get licence na di only place where modern player fit meet di 1890 wheel.
Questions wey pipo dey ask
No. To change bet once di result don dey known na fraud anywhere wey di game legal.
For Nevada, to use such device don be felony since 1985. For oda places di law dey different; see Advantage Play.
Dem question am many times and, as e tok am and later interviews, court never find am guilty. Since den e don dey advise casinos on game protection.
E don happen: di Smithsonian get one wheel of di 1930s wey dem build for dat. Casinos wey get licence dey check for magnets before table open, and for New Jersey di ball must no get any metal.
Prosecution. Courts don sentence dealers and dia partners for di United States, New Zealand, England and Singapore.
Play with Maths
Try dem by yourself first. Each solution dey folded; open am when you ready.
One past-posting team dey keep di layoutequipmentLayoutDi betting grid wey dem print for di table. Dem also dey call am: table, felt, cloth.Read di whole tin → busy by covering di third dozenbetDozen1–12, 13–24 or 25–36, e dey pay 2:1.Read di whole tin → every spin for American wheel: 4 chipsmoniChipToken wey stand for one fixed amount, wey you put on top di layout to make bet. Dem also dey call am: check.Read di whole tin → on each of di numbers 25 reach 36 and 20 chips on di dozen box. Wetin e dey win when di dozen hit, wetin e dey lose when e miss, and how much di waiting dey cost?
Show di solution
Answer +136 chips when e hit and −68 when e miss, so for average di team dey lose 3.58 chips every spin, di normal 5.26% of 68. Di dozen dey hit about once every 3.2 spins.
Every spin, 68 chips dey go down. If one of 25 reach 36 come out, di 4 chips on am dey win 35 to 1 and dem dey come back with dia stake: 144 chips. Di dozen dey pay 2 to 1 for 20 chips: 60 back. Dat na 204 for 68 wey dem stake, +136. If not, all 68 go lose.
Average: (12 × 136 − 26 × 68)/38 = (1,632 − 1,768)/38 = −3.58 chips every spin, wey be 5.26% of 68. Di dozen dey come out 12 times for 38, once every 3.2 spins for average.

For French: rouge.Read di whole tin → or blackbetBlackEven-money bet for di 18 black numbers. For French: noir.Read di whole tin →. Imagine sey di steering dey work only once for 18 spins and di rest dey fair, for double-zerowheelZeroDi one green pocket wey no even-money, dozen or column bet dey cover; na im be di source of di house edge. Dem also dey call am: single zero, 0.Read di whole tin → wheel, and di dealer dey always steer against di colour wey you bet. How much $10 bet on red dey cost you now? How often di steering go need to work make di house keep one third of every bet?
Show di solution
Answer Once for 18 spins dey double di house edge, from 5.26% reach 10.53%: $1.05 for each bet instead of $0.53. To keep one third of every bet, di steering must work 8 spins for 27, about 30% of di time.
For fair spin, red dey win 18 times for 38. Spin wey dem steer no dey ever win. If di steering dey work with probabilitymathsProbabilityDi chance of one outcome, from 0 to 1 or from 0% to 100%. One number: 1/37 = 2.70%.Read di whole tin → s, red dey win with probability (1 − s) × 18/38.
With s = 1/18: (17/18) × (18/38) = 17/38. Di bet dey win $10 with chance 17/38 and lose $10 with chance 21/38, average of −$40/38 = −$1.05, wey be 10.53% of di stake. Di figure for fair wheel na −$20/38 = −$0.53, or 5.26%.
For one third: di bet worth 2p − 1 of di stake, where p na di chance to win, so 2p − 1 = −1/3 dey give p = 1/3. Then (1 − s) × 18/38 = 1/3, so 1 − s = 38/54 and s = 16/54 = 8/27, about 29.6%.
Na why wheel wey dem tamper worth di risk for house wey dey do wayo, and why dem fit use am small small: to steer one spin for eighteen, against only di biggest bets, hard to see from di rail and e dey double wetin dem dey take.
