One doctor from Stettin

Dem born Richard Wilhelm Jarecki on 1 December 1931 for Stettin, wey dat time dey Germany and now na Szczecin for Poland. Im papa na dermatologist and im mama family get shipping company. Di family na Jewish and dem leave Germany for di late 1930s. E grow for Asbury Park, New Jersey, study for Duke University, and go back Germany for im medical degree, wey e collect for Heidelberg for 1958. E marry Carol Fuhse, one nurse wey train for anaesthesia, for 1964. For 1967 di two of dem move go Heidelberg, where e do research for forensic medicine for di university. Im own description of di post for 1969 na associate researcher, even though di newspapers make am professor.

Di method

Di story of di Richard Jarecki roulette system come from wetin Carol Jarecki tok for 2018. Di two of dem and few helpers write down di result of every spin of one wheel wey dem choose, as dem dey find numbers wey dey win more often pass as dem suppose, becos of small fault from how dem make am or from wear. One wheel fit take more pass 10,000 spins and reach one month, and some wheels no show anytin wey worth to bet. She no claim sey e new: “No be sometin wey e invent. Na sometin wey e perfect.”

Dem play for plenty casinos, like Monte Carlo, Divonne-les-Bains, Baden-Baden and Sanremo, where e become regular customer. Europe fit am becos dia wheels get one 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 →, 37 pocketsequipmentPocketOne of di 37 small boxes wey get number for di rotor. Dem also dey call am: slot, cup.Read di whole tin → against 38. One report of February 1969 record one croupierpipoCroupierDi dealer for roulette table.Read di whole tin → for Sanremo wey tok sey e no dey ever play alone: e dey run five or six tables at once, wit about ten pipo wey dey put di bets and report di numbers.

E also learn how to sabi one wheel from anoda. Workers for Sanremo tok sey one evening dem move every table; e stand for long time, e no understand, den e go straight to di exact tables wey e don dey play. Di explanation of Carol Jarecki na sey e don memorise di small cuts and scratches.

Fret wey get small cut under loupe, near one tally where one number stand out.

Why e must be ten thousand spins

For 10,000 spins of fair single-zero wheel, each number dey show about 270 times, plus or minus 16. Number wey show 319 times dey three of dose “plus or minus” ahead, and luck almost never dey do dat. E dey win once for about 31 spins, and for 35 to 1, bet on am dey bring 15%.

Now take 1,000 spins. Fair number dey show about 27 times, plus or minus 5, and wit 37 numbers for di wheel, di one wey get luck pass go usually get 37 hits or more. E go look like hot numbermythHot numberNumber wey don show pass wetin dem expect recently. For fair wheel e no dey predict anytin.Read di whole tin → but e no mean anytin. Di month of notes na di price to sabi pocket wey get fault from pocket wey just get luck. See Size of Di Sample.

1,00027 times, ± 542 times+51%
5,000135 times, ± 11170 times+22%
10,000270 times, ± 16319 times+15%
20,000541 times, ± 23609 times+10%
Single-zero wheel. “Plus or minus” na one standard deviation, di square root of spins × 1/37 × 36/37. Di more spins, di smaller di fault wey you fit separate from luck.

Myth: Some Numbers Don Due

Wetin nobody sabi

No source tok which numbers e bet, how many of dem, how much e stake or how big im advantage be. Barnhart, wey write di only book chapter about am, tok sey di fault for Sanremo come from wheels wit low separators between di pockets; e no give di basis for dat. Where im stake moni come from, no document show am too. When dem ask am for 1969, e tok sey e dey play wit im winnings.

Di computer story

Jarecki tell reporters sey na computer for di University of London dey do di work, and sey e dey phone di numbers of di day to am every night; Barnhart tok sey di machine na Atlas wey im friends dey run. One obituary of 2018 tok am clear sey no electronic help dey, only observation, and Barnhart call di computer explanation lie wey fool casino managers, di gaming police and di public.

Im own statements dey change. For February 1969 e tell one newspaper for Trieste sey e use computer for some time, only to save arithmetic, and sey computer no dey think or invent. For one newspaper interview for May 1969, e describe system wey base on di last three numbers wey show, and dat one no be how pipo dey play 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 → at all. By dat time, Sanremo don already dey put di simpler explanation for im front: sey e dey win becos e sabi how di wheels don wear. E deny am.

Di cover story of Jarecki: di numbers of di day wey e dey phone every night to one computer for London.

Computers for Roulette

Sanremo, winter 1969

Di weeks for im career wey get di best documents na dis ones. Di town control di casino, so di town council get di last word.

Jarecki and di Sanremo casino

Im lawyers argue sey professor of forensic medicine no fit be professional gambler. Di council cancel di ban and promise am honour card wit free entry.

December 1972

Dem allow am back afta second ban, according to one report from Italian news agency wey Barnhart quote.

1973 or 1974

E go back to di United States.

Wetin di managers tok

Im own line about di ban na di one wey last pass: “If casino managers no like to lose, make dem go sell vegetables.” One newspaper report of May 1969 quote Robert Lardera, wey e call di managing director of di casino, sey Jarecki na “danger to every casino for Europe”. Oda sources name di manager of dat time as Luigi Bartolini, wey dem quote sey e call Jarecki very nice man wit clear mind and strong nerves. Jarecki tok for 1969 sey many casinos don ask am for private make e no come back, and sey no one order am to comot. Carol Jarecki tok much later sey full bans no dey common, becos e dey make friends wit di workers.

Wetin di casinos change

Sanremo move im tables around, but dat one no stop am. One obituary of 2018 report sey di casino den change about two dozen wheels, and dat one stop am. E add sey dem come dey make wheels in general wit more care, wit less faults to find, and sey im advantage fade. No source show casino wey order better wheels becos of am, and dem no name any wheel maker.

How to Measure Wheel with Hand and Tools

Afta roulette

Back for di United States, e trade commodity futures for imself, mostly silver and gold, and e continue to play roulette and blackjack for Las Vegas and Atlantic City. About 1998 e move go Manila, becos e prefer dia casinos. E die there on 25 July 2018, when e be 86. As im wife tok am, di last time wey e play na di December before, for one tournament for Manila, and e come first.

Na wetin e tok dat time. One obituary of 2018 and di book of Barnhart both tok sey di computer na cover for to record spins by hand.

Dem ban am from casinos?

Sanremo ask am make e stay away for January 1969, ban am for February and allow am back inside few days. For oda places, na mostly private request dem make, sey make e no come back.
