Di name
Roulette na French for “small wheel”. Pipo dey use di word for oda wheel games before e settle on dis one: one regulation of 1758 for New France, di French colony for di St Lawrence, don already ban “dice, hoca, faro and roulette”, as Shelley (1988) report, but e no tok how dat roulette be. For early English sources, pipo dey sometimes call di game “roulet” or describe am as “di French E.O.”. By di 1820s, “roulette” mean one particular game everywhere for Europe.
Di two zeros
Di first Paris wheels get both 0 and 00, and dat one give di house edge of 5.26% for wheel wey get 38 pockets. Di single-zero wheel na business move by di Blanc brothers for Bad Homburg for 1843, to pull players from di oda spas. Di American wheel keep both zeros becos di game don reach America before di change, and nobody for there get competitor wey dem need beat for price. Some early American wheels go further: one layout of di 19th century get only di numbers 1 to 28 wit 0, 00 and one eagle, e pay one single number 27 for 1, edge of 12.90%, and e take 9.68% on im columnsbetColumnTwelve numbers for one column of di layout wey stand from up to down, e dey pay 2:1.Read di whole tin → and colours. E no last.

To change di colours one by one, and to spread high/low and odd/even. Dem settle di exact order for di 19th century and e never change.
Play with Maths
Try dem by yourself first. Each solution dey folded; open am when you ready.
Biribi dey pay back 64 for 1 for one number out of 70, di stake inside: 63 to 1. Which edge be dat? If e offer bet on two numbers, which 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 → go keep di same edge?
Show di solution
Answer Di edge na 6/70, 8.57%. Bet on two numbers go pay 31 to 1, whole number.
One number dey win once for 70 draws and e dey pay 63 unitsmoniUnitDi 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 →; di oda 69 draws dey lose 1: (63 − 69)/70 = −6/70, edge of 8.57%. To tok am anoda way, di bank dey pay 64 back where fair gamemathsFair gameGame where no side get edge: every bet get expected value of zero.Read di whole tin → go pay 70.
Bet on two numbers for x to 1 dey win two times for 70 draws: 2x units wey you win against 68 wey you lose, expected valuemathsExpected valueDi average result for each bet for di long run. −1/37 of di stake for every standard European bet.Read di whole tin → of (2x − 68)/70. Make 2x − 68 = −6: x = 31. Dat na 32 back for 1, half of 64.
Di payouts of Biribi dey follow 64/n back for 1, and 64 dey divide clean into half for 1, 2, 4, 8, 16 and 32 numbers, so dose bets dey come out whole. Di 36 of roulette dey divide by 1, 2, 3, 4, 6, 9, 12, 18 and 36, wey fit layoutequipmentLayoutDi betting grid wey dem print for di table. Dem also dey call am: table, felt, cloth.Read di whole tin → of rows of three.
Di 70 numbers of Biribi, wey dem arrange for rows, leave space for four bets on three numbers. By di rule wey dey behind di 8.57% edge of di single number, wetin bet on three numbers suppose pay? How much di whole payouts wey dey near go cost?
Show di solution
Answer 20⅓ to 1. To pay 20 to 1 go cost 10%; to pay 21 to 1, 5.71%.
Di rule from di puzzle wey dey up: bet on n numbers dey pay 64/n back for 1. For three numbers na 64/3 = 21⅓ back, or 20⅓ to 1, wey no 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 → fit pay.
Bet on three numbers for x to 1 dey win 3 times for 70 draws and lose 67 times: expected value of (3x − 67)/70. For 20 to 1: −7/70, 10%. For 21 to 1: −4/70, 5.71%.
To round down by one third of unit dey cost di player almost one point and half; to round up dey give back almost three points. Thirty-six, with im many divisors, dey save roulette from dat choice for every bet except di American five-number one.
Di eagle wheel of di 19th century get 31 pocketsequipmentPocketOne of di 37 small boxes wey get number for di rotor. Dem also dey call am: slot, cup.Read di whole tin →, 1 reach 28 plus 0, 00 and one eagle, and e dey pay 27 for 1 for one number. Im columnbetColumnTwelve numbers for one column of di layout wey stand from up to down, e dey pay 2:1.Read di whole tin → and colour bets dey cost 9.68%. Wetin bet on four numbers suppose pay, “for 1”, make e cost di same?
Show di solution
Answer 7 for 1, wey dey cost 3/31 = 9.68%.
Bet wey dey pay X for 1 dey give back X units, stake inside, when e win. Bet on four numbers dey win 4 times for 31, so e dey return 4X units for every 31 wey you stake: expected value of (4X − 31)/31.
For 7 for 1 na −3/31, 9.68%, di same as di columns and colours. For 8 for 1 e go be +1/31, edge for di player. So di rule of di eagle wheel na (28 − n)/n to 1, three house pockets out of 31.
