Di Arithmetic

Expected valuesmathsExpected valueDi average result for each bet for di long run. −1/37 of di stake for every standard European bet.Read di whole tin → dey add up. Red na −1/37 of im stake; di column chip na −1/37 of im stake; togeda dem be −1/37 of di total. Di hedge don buy hit rate wey high pass and net 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 → wey low pass for each hit, for exactly di fair exchange rate minus 2.70%. Di Bet Builder tool dey list all 37 results for any set of chips and e dey show how di results dey spread and di EV (wey no dey change).

Red Plus Black

Dis na di extreme case. Every spin except zero dey return di stake; zero dey lose both. Di expected value na −2.70% of di total, and di upside na zero. Na di only roulette combination wey no get any point at all, and pipo dey put am more often pass wetin you go think, usually person wey dey hedge one system for di middle of di cycle.

One System Wey Get Name: Bohemia (1959)

For 1959, di Cuban magazine Bohemia print one system wey John Scarne later report and scatter: one unitmoniUnitDi base stake wey system or player dey work with. Dem dey describe progressions in units so dat dem go fit work for any table.Read di whole tin → on black and one on di third column, wey get eight red numbers and only four black ones (6, 15, 24, 33). Di pipo wey dey sell am promise profit of 4 units every 38 spins of one double-zero wheel; if you count am honestly, di same wheel dey give loss of 4. Count di results for one European wheel. One black number for di third column dey win both bets, +3; one red one dey win di column and lose black, +1; any oda black dey win black and lose di column, 0; di oda ten reds and di zero dey lose both, −2. For 37 spins, dat one na 12 + 8 + 0 − 22 = −2 units on 74 wey you stake, 2.70%, like for every combination. Di system dey win or break even for 26 spins out of 37, and na dat one make am look like sense. Bollman (2024) add one three-two version, 3 units on black and 2 on di column, for di same price.

To Hedge One Progression

Players wey don enter deep for one MartingalestrategyMartingaleProgression wey dey double di bet afta every loss. Check di Strategy section to see wetin e dey do and wetin e no dey do.Read di whole tin → dey sometimes divide di big bet between red and one dozen, or dem add zero, so dem go “protect” am. Di protection dey cost 2.70% of imself and e dey change which results go recover di cycle. E no dey change di probabilitymathsProbabilityDi chance of one outcome, from 0 to 1 or from 0% to 100%. One number: 1/37 = 2.70%.Read di whole tin → sey di cycle go end badly; e dey change how bad e go be, for both direction. One rule to stop dey cheap pass and e dey work.

When Di Pattern Dey Cost More: One Dealer Sector System

For one double-zero wheel, one cover dey cost more pass di rest. Bollman (2021) describe one system wey one Las Vegas dealer recommend, wey dey target two arcs of di American wheel: di eight pocketsequipmentPocketOne of di 37 small boxes wey get number for di rotor. Dem also dey call am: slot, cup.Read di whole tin → 2, 0, 28, 9, 26, 30, 11, 7 and, for di opposite side, 1, 00, 27, 10, 25, 29, 12, 8. For dat wheel, di two arcs just happen to fall inside blocks of di layoutequipmentLayoutDi betting grid wey dem print for di table. Dem also dey call am: table, felt, cloth.Read di whole tin →, so three chips dey cover dem: one on di five-number bet (0, 00, 1, 2, 3), one on di six linebetSix lineSix numbers for two rows wey dey near each oda, e dey pay 5:1. For French: sixain.Read di whole tin → 7–12 and one on di six line 25–30. Dat one na 17 numbers, di two arcs plus 3, for three chips. Di catch na di first chip. Di layout no get bet on 0, 00, 1 and 2 alone, and di five-number bet na di only American bet wey dem price for 7.89% instead of 5.26%. E dey pull di whole pattern go −7/38 of one unit on 3 units wey you stake, 6.14%. For one American table, any cover wey no include di five-number bet dey cost 5.26%; dis one dey cost more becos e include am.
