Kufundza umlandvo wekujikeleta loshicilelwe
Bacondzisi labanyenti bemdlalo lobukhoma bashicilela umlandvo wonkhe wekujikeleta. Nanku kutsi ungawufundza njani, uwuhlante njani, naloko longakutjela nalokungeke ukutjele kona.
Umlandvo wekujikeleta luhlu lwemiphumela lenesikhatsi, kanyenti ngelitafula ngalinye. Uyintfo yekucala yekuhlatiya kuchema nangabe, futsi kuphela nangabe, ukhomba inhloko yelisondvotinsitaInhloko yelisondvoKusho lokufanako ne-rotor: ingcenye lejikeletako lephetse tinombolo.Fundza konkhe → yinye esikhatsini lesingenako kulungiswa. Leminyenti ayikwenti loko, futsi leminyenti mifisha kakhulu.
Lokukhona emlandvweni
Sikhatsi, libito lelitafula, umphumela (0–36), ngaletinye tikhatsi libito le-croupier ne-ID yemjikeleto. Kulibhuku laloko lokubhalwe yi-server yemdlalo, ngako kunembile. Loko lokungavamile kube kuwo kutsi ngiyiphi inhloko ye-rotortinsitaI-rotorIngcenye yelisondvo lejikeletako lephetse imigodzi.Fundza konkhe → lebeyisetafuleni ngaleso sikhatsi, lokuyintfo ledzingwa kuhlatiya kwekuchema, ngobe tinhloko tishintjaniswa emkhatsini wetitjatinsitaSitja selisondvoIncenye yangephandle yelisondvo lengagucuki: imphetfo yelukhuni noma yentfo lehlanganisiwe lephatse umzila welibhola ne-apron, ngekhatsi kwayo i-rotor iyajikeleta.Fundza konkhe →.
Kuhlanta idatha
Hlola tikhala (kulungiswa, kuvalwa), ema-ID emjikeleto laphindziwe, imiphumela lengaphandle kwa-0–36 (00 etafuleni laseMelika, kujikeleta kwekuhlola), nekushintja kwekushintjana kwema-croupier lokungakhombisa kushintjwa kwenhloko. Hlukanisa idatha ibe tincenye kunoma ngusiphi sikhala lesidze kunemahora lambalwa; tsatsa tincenye njengemasondvo langahle ehluke. Nangabe libito lelitafula kuphela lokuhlonzako, cabanga kutsi inhloko yashintjwa okungenani kanye ngenyanga.

Bese uxuba imiphumela ngekhatsi kwencenye bese uyaphindza: tibalo letixutjiwe tikhombisa kutsi kulunga kubukeka njani ngalobu bukhulu besampula, futsi nangabe tibalo takho tangempela tingekho ngaphandle ngalokucacile kwebubanti betibalo letixutjiwe, awukatfoli lutfo. Sihlatiyi sekuchema kwelisondvo le-roulette sikwenta loku esiphequluli.

Kutsatse njengesizatfu sekubuka incenye lelandzelako yelitafula lelifanako, futsi ulindzele kutsi kunyamalale.

Imilandvo ilungele yini
Kuchatsanisa simemetelo se-croupier nelibhuku. Kukala sivinini (kujikeleta ngelihora) kute kubalwe kulahlekelwa lokulindzelekile.

Elisondvweni lelinemigodzi lengu-37, kujikeleta lokungu-8 kwanele kutsi litfuba libe ngetulu kwesigamu.Fundza konkhe →, budze betichungechunge nekusabalala kwetinombolo letishisako edatheni yangempela. Kwakha umuva lowongela imali: liphethini ekujikeleteni lokungu-500 akusilo liphethini. Futsi, ngemcondvo, njengelikhasi lekucala lelibhuku lekuchema kulungiswa kwesimanje lokutawulenta lingasasebenti ngaphambi kwekutsi ligcwale.

Imibuto
Kuyivelakancane. Emakhasino akhombisa tinombolo letingu-20 futsi agcina letinye ngekhatsi.
Kuvuleleka, futsi ngobe badlali bayacela. Akubalahlekiseli lutfo elisondvweni lelinakekelwako.
I-chi-square yencenye yonkhe. Nangabe ingakhombisi lutfo lolumangalisako, yima.
Lokuhlekisako
Idatha ngeyangempela. Lisondvo leliyichazako kungenteka lingasekho.
