History
Casino floors did not invent chance. They packaged older tools — cubes, wheels, cards, pegs — under lamps. The four games here sit on that longer shelf.
Cubic dice with pip marks appear in the archaeological record of the ancient Near East and Egypt. Knucklebones (astragali) are older still. A two-sided toss — our Scarab Streak — is the same idea cut down to one binary call, a method used for decisions in many cultures.
European roulette settled into two main layouts: a French single-zero wheel (37 pockets) and an American double-zero wheel (38). The single-zero version is the one with the milder house edge. Carnival “money wheels” used a different logic: repeated low numbers on wide slices, rare high numbers on thin ones — the pattern Spur Wheel follows.
Playing cards reached Europe from the Islamic world in the 14th century, after earlier packs in China. Ranking a card and asking whether the next is above or below is among the simplest derived games; it needs a known order (here, Ace high) and a rule for ties. North Shore Hi-Lo uses a 52-card deck without replacement, which is the ordinary French-suited pack.
Francis Galton described a quincunx — a board of pins that demonstrates the binomial distribution — in the late 19th century. Discs that bounce left or right with equal chance collect in the centre. Valve Drop is that classroom object with multipliers printed on the bins. Television and carnival peg-drops are later cousins; we do not borrow their brand names.
A fair 37-pocket wheel that pays 35 to 1 on a straight number has a house edge of 1/37, about 2.7%. Adding a second zero raises the edge. Spur Wheel is not roulette; it is a money wheel. The comparison is here because visitors often mix the two.
Independent tosses were already the working assumption of 17th-century probability (Pascal, Fermat, Huygens). Streaks happen. They do not make the opposite face “due.”
