Products that borrow from the rest
The last decade produced a set of products that recombine the mechanics of the older ones: a casino game with a player-chosen exit, a sports bet on a simulated match, a fantasy contest priced like a pool, a lottery-style sweepstake wrapped around a casino, and an exchange on real-world events regulated as a financial product. Each is worth understanding on its own terms, because each has grown fast and each has tested a regulatory boundary.
Crash games
A multiplier starts at 1 and rises; at a random moment it crashes to zero; the player cashes out before the crash to win the multiplier at that moment, or loses the stake. Popularised by crypto casinos with a provably fair scheme (the crash point committed cryptographically before the round), the format has since been taken to regulated online casinos by mainstream studios: Spribe, which makes Aviator, says the format became popular in crypto casinos and that it was among the first to bring it to regular online casinos.
Mechanics: the house edge is stated and built into the crash-point distribution (Aviator, for example, lists a return to player of 97%, a 3% edge); the player chooses the variance by cashing out early (low, frequent wins) or late (rare, large). Rounds take seconds, are social (other players' cash-outs are visible) and are the purest expression of pace as a product feature. Regulators treat them as casino games (in Britain a crash game is a game of chance played for a prize, which the Gambling Act 2005 defines as gaming); the harm concern is speed and the chasing behaviour the visible near-misses encourage.
Virtual sports
Simulated sporting events (football matches, horse and dog races, tennis) rendered as animation with results drawn from an RNG and odds set from the simulation's probabilities. Rounds run every few minutes, all day, filling the gaps in the real calendar. The product is sports betting's format with casino's mechanics: fixed-odds prices, an RNG outcome, a certified RTP. Offered in retail betting shops as well as online. Despite the casino mechanics, the major regulated markets treat them as betting on an event, even though the event is not real: the Gambling Act 2005 defines a virtual race or event as one generated or determined by computer, and in Britain betting on virtual events needs its own betting licence, separate from the licence for betting on real events; Italy regulates them as fixed-odds bets on simulated events, shown in betting shops and online, with the random numbers supplied by the national totalisator.
Esports betting
Fixed-odds betting on competitive video game events (the major titles have professional leagues with official data). Mechanically identical to sports betting, with the same pricing, in-play and integrity issues, and a younger customer base. The market is smaller than its early hype suggested and larger than its critics say; the integrity concerns (young players, low pay in lower tiers, easy manipulation of in-game events) mirror sport's and are more acute.
Daily fantasy sports and pick-style products
Players build a lineup of real athletes within a salary cap; the lineup scores from the athletes' real performances; entrants compete for a prize pool from which the operator takes a rake. Daily fantasy grew in the US under a fantasy sports exemption in the Unlawful Internet Gambling Enforcement Act of 2006, which excludes contests whose outcomes reflect participants' skill and are determined predominantly by the statistical performance of athletes in multiple real events (state law still applies). It was the launchpad for DraftKings, which says it was founded in 2011 with a singular focus on daily fantasy; DraftKings and Flutter's FanDuel both now run sportsbooks, online casinos and prediction-market products alongside their fantasy contests. Pick-style products (choose whether a player exceeds a statistical line, combine several picks, paid at fixed multiples) look like fantasy and behave like parlays on player props; regulators in some US states have challenged them (Arkansas sent cease-and-desist letters to two operators in 2024 over what it called "player prop bets", which it treated as unlicensed sports betting, and New York's Gaming Commission settled with Underdog in 2025 over contest types it said were not permitted), and the category has been reshaped by that.
Mechanics: peer-to-peer fantasy is a pool with a rake (skill against players); pick-style against the house is fixed-odds (skill against the price). The distinction decides the regulation, which is why the operators argue about it.
Sweepstakes casinos
Casino games played with two virtual currencies: one bought with money and worthless, the other (the sweepstakes coins) given free with purchases and redeemable for cash prizes. The structure uses sweepstakes law (a promotion with no purchase necessary) to offer casino-style play in US states where online casino is illegal. Fast-growing, contested by state regulators and legislators, banned in several states (California's AB 831, approved in October 2025, made it unlawful to operate an online sweepstakes game that uses a dual-currency system), and the subject of the Sweepstakes and Social Casino course. Mechanically a slot with a legal wrapper; the player experience is a casino.
Social casino
Casino games played for virtual currency that cannot be redeemed; players buy more currency when they run out. Generally not gambling in the legal sense, since nothing of value is won, though in 2018 a US federal appeals court held that the virtual chips in one social casino game were a "thing of value", making it illegal gambling under Washington law. A large business (dominated by a few publishers) that sits at the edge of the industry, shares its studios and its psychology, and attracts regulatory attention where it resembles gambling too closely.
Prediction markets
Exchanges where customers trade contracts that pay a fixed amount if an event happens: an election result, an economic release, a sporting outcome. Prices move with supply and demand and read as probabilities. In the United States they operate as exchanges licensed by the Commodity Futures Trading Commission under federal derivatives regulation rather than state gambling licences, which they have used to offer sports event contracts in many states, including California where sports betting is legal only on tribal lands. That has produced litigation with state regulators and tribes, and the courts have not agreed: in April 2026 the federal appeals court for the Third Circuit held that federal law likely pre-empts New Jersey's gambling laws as applied to these contracts, while in September 2026 the Ninth Circuit held that contracts entered from tribal land in California likely breach the Indian Gaming Regulatory Act. Mechanically a betting exchange (customers against customers, the operator taking a fee) with a financial-regulation wrapper and a market-maker layer providing liquidity. The Prediction Markets course covers them; for this course the point is that they are the newest example of a product testing the definition of gambling.
Lottery betting and secondary lotteries
Fixed-odds bets on the outcome of official lottery draws, offered by operators rather than the lottery, at prices set from the draw's probabilities, matching the official prize tiers, with the largest pay-outs typically covered by insurance. Legal in some markets, banned in others (usually to protect the official lottery's revenue), and some jurisdictions have legislated against it: Britain's Gambling Act 2005 bars betting licensees from taking bets on the National Lottery, and in 2018 Australia amended its Interactive Gambling Act to prohibit betting on the outcome of Australian and overseas lottery draws.
What the newer formats share
Each takes a mechanic from an older product (RNG, fixed odds, pool, exchange), changes the wrapper (a multiplier, a simulation, a salary cap, a sweepstakes, a derivatives licence), and finds a customer or a jurisdiction the older product could not reach. Each then meets a regulator asking whether the wrapper changes the substance, and the answer has gone both ways. For a product person, the lesson is that innovation in gambling is mostly recombination; for a compliance person, that the substance is what gets regulated; and for anyone reading the industry, that the next boundary test is already being built.
The course in one paragraph
Every gambling product is a stake on an uncertain outcome with a payout schedule that returns less than the stake over time; they differ in how the edge is built (in the rules, in the price, as a commission), how much variance they carry and who chooses it, how much skill changes the outcome and against whom, how fast they resolve, and how fairness is proved. Sports betting prices uncertainty; slots and casino games fix it by design; live casino makes it visible; poker, bingo, lottery and pools share it among players; the newer formats recombine all of that in new wrappers. Knowing the mechanics is knowing the products.
