Red plus black

Seema wala case. Zero ke alawa har spin stake wapas deta hai; zero par dono haar jate hain. Expected value total ka −2.70%, upside zero. Yeh roulette ka akela combination hai jo poori tarah bekaar hai, aur yeh aapki soch se zyada baar lagaya jata hai, aksar koi aisa jo cycle ke beech apne system ko hedge kar raha ho.

Naam wala ek system: Bohemia (1959)

1959 mein Cuban magazine Bohemia ne ek system chhapa jise baad mein John Scarne ne report karke tod diya: ek unitpaisaUnitBase stake jismein koi system ya player kaam karta hai. Progressions units mein batayi jaati hain taaki kisi bhi table par laagu hon.Poora padhein → black par aur ek teesre column par, jismein aath red numbers hain aur sirf chaar black (6, 15, 24, 33). Bechne walon ne double-zero wheel ke har 38 spins mein 4 units munafe ka vaada kiya; imaandaari se ginein toh usi wheel par 4 ka nuksaan aata hai. European wheel par outcomes giniye. Teesre column ka black number dono bets jeet-ta hai, +3; wahan ka red column jeet-ta hai aur black haarta hai, +1; koi aur black, black jeet-ta hai aur column haarta hai, 0; baaki dus reds aur zero dono haarte hain, −2. 37 spins mein yeh 12 + 8 + 0 − 22 = −2 units hai 74 lagaye gaye par, 2.70%, har combination ki tarah. System 37 mein se 26 spins par jeet-ta ya barabar rehta hai, aur isi se woh chalaak lagta tha. Bollman (2024) ek teen-do version jodte hain, 3 units black par aur 2 column par, usi keemat par.

Jab pattern zyada mehenga pade: ek dealer ka sector system

Double-zero wheel par ek cover baaki sab se mehenga padta hai. Bollman (2021) ek system batate hain jo Las Vegas ke ek dealer ne suggest kiya, American wheel ke do hisson par: aath pocketssaamanPocketRotor ke 37 numbered khaanon mein se ek. Doosre naam: slot, cup.Poora padhein → 2, 0, 28, 9, 26, 30, 11, 7 aur unke saamne 1, 00, 27, 10, 25, 29, 12, 8. Us wheel par yeh do hisse sanyog se layoutsaamanLayoutTable par chhapa betting grid.

French mein: sixain.Poora padhein → 7–12 par aur ek six line 25–30 par. Yeh teen chips mein 17 numbers hain, do hisse plus 3. Pench pehle chip mein hai. Layout mein sirf 0, 00, 1 aur 2 par koi bet nahi hai, aur five-number bet akeli American bet hai jiski keemat 5.26% ki jagah 7.89% hai. Yeh poore pattern ko 3 units lagane par ek unit ka −7/38, yaani 6.14%, tak kheench leti hai. American table par five-number bet ko chhodne wala koi bhi cover 5.26% ka padta hai; yeh wala zyada padta hai kyunki ismein woh shaamil hai.
