Experimental study finding gambling advertising content on platforms like X/Twitter is significantly more appealing to children and young people than to adults, and that children report predominantly positive emotional responses to gambling ads where adults report predominantly negative ones — evidence the same creative can have opposite emotional effects by age.

Newall et al. propose a taxonomy of deceptive design across online gambling platforms, cataloguing hidden self-exclusion/limit-setting tools, inducements with obscured conditions, minimum-balance withdrawal requirements, high default stake/deposit settings, artificial urgency prompts, and account-closure friction. Framed explicitly using the behavioural-economics 'sludge' concept alongside dark patterns/dark nudges.

GREO plain-language evidence synopsis summarising the influencer-marketing-to-youth literature for a policy audience, concluding the evidence consistently shows normalisation and increased positive attitudes toward gambling among youth exposed to influencer content, while flagging the underlying evidence base as still mostly observational rather than causal.

Adult performer Johnny Sins became a 1win brand ambassador, appearing in promotional content demonstrating the 1win app's registration flow and placing symbolic bets; some content reportedly carried 18+ warnings or was hosted on age-gated platforms, while other distribution channels (mainstream social media) reportedly did not carry equivalent restriction.

Audit of mobile-game compliance with South Korea's 2024 mandatory loot-box probability disclosure law (including pity-threshold disclosure) finds materially higher and more consistent compliance than under the industry's prior voluntary self-regulation regime, offering a direct natural experiment on statutory-mandate versus self-regulation efficacy.

An independent audit referenced within the 2025 Addiction dark-patterns taxonomy paper found that, across 50 casino apps, the average time to locate the account-closure function was 4 minutes 32 seconds, while the deposit function was reachable in under 8 seconds — a roughly 34-fold asymmetry in friction between depositing and closing an account.

Cross-sectional survey of Chinese young-adult gacha players identifying demographic and psychological correlates (e.g., impulsivity, escapism motives) that predict problem-gambling risk within the gacha-playing population specifically, rather than gaming or gambling populations generally.

Illegal/unlicensed operators run search advertising targeting terms self-excluded players use to seek workarounds (e.g. 'Not on Gamstop' in the UK). Sweden's Spelinspektionen separately confirmed some Spelpaus-registered individuals continue receiving marketing from illegal sites, though it denies any data breach from the register itself.

Reports crypto-casino users skew young (18-35 ~60% of audience, 25-34 subset ~40%) and male (70%+), younger and more male-skewed than traditional online gambling. Geographic search-interest data shows the US, Germany, UK, Canada, and France leading by search volume, while Eastern Europe, Latin America, and Southeast Asia are cited as high-engagement regions, partly attributed to restrictive local gambling laws pushing players toward less-regulated crypto platforms.

Tests independently-designed (non-industry) Australian safer-gambling messages on UK and US bettor samples, finding the independently designed messages outperformed pre-existing industry-designed messages on self-reported behavioural intention measures, supporting policy moves in Australia and (per the message-effectiveness literature above) informing planned UK message redesign.

ANCHOR — The 2024 US presidential election market was Polymarket's largest to date, with $3.2-3.3B traded on that single contract and roughly $9B total platform volume for 2024 — the historical benchmark against which 2026 World Cup-driven volumes (now regularly exceeding the entire 2024 annual total in a single month) are compared.

Documents that a sample of 223 distinct inducement offers across 15 categories carried complex, frequently misunderstood wagering-requirement terms — 58% of surveyed players underestimated the actual playthrough requirement attached to their inducement — and proposes a standardised economic-value disclosure format (expressing an inducement's real expected value rather than its headline size).

Myles et al. used EEG to show that losses-disguised-as-wins (LDWs) — net-loss outcomes accompanied by win-style audiovisual celebration — evoke the reward positivity ERP component, the same neural signature elicited by genuine wins. This is neurophysiological confirmation that LDWs are processed by the brain's reward system as rewarding despite being a net financial loss.

Survey of youth advertising recall around a single major global sporting event found high recall of odds/inducement content specifically: 95.6% recalled odds advertising, 89.5% recalled betting inducements, and majorities recalled in-play betting and sign-up offer promotion.

Field experiment comparing multiple safer-gambling message variants over five weeks of live sports/race betting exposure, finding meaningful differences in effectiveness between message wordings, with self-appraisal-style messages ('are you in control?') outperforming purely informative messages.

Palmer, Ferrari and Clark ran a three-study conceptual replication of the near-miss effect in online slots. Near-misses produced faster speed of subsequent play and larger bet increases in two studies, but self-reported arousal and motivation differences were modest or non-significant, indicating the behavioural effect replicates more reliably than the subjective effect.

Qualitative study of young people's own accounts of celebrity/influencer gambling marketing found participants view the tactic as effective specifically because it increases trust in gambling brands and lowers perceived risk of gambling, in the young people's own words rather than as researcher inference.

A large online sample study found players systematically overestimate how often they won after sessions containing LDWs, with overestimation present among both low- and high-risk gamblers. A brief explanatory video and pairing LDWs with loss-associated sound cues both reduced the overestimation effect.

Qualitative study of young sports bettors' own perceptions of inducement offers found sign-up and bonus-bet inducements were perceived as more behaviourally influential than stake-back or odds-boost inducements, and that younger, lower-socioeconomic-status, and already-at-risk gamblers focused on inducement upside while discounting long-term risk.

ANCHOR (with current continuation) — 1xBet signed adult-film actress Eva Elfie as a 1.5-year-minimum brand/eSports ambassador in September 2022, deploying her at major esports events. As of mid-2025 reporting the partnership continued with exclusive branded events, showing this is a sustained multi-year tactic predating the 2025-2026 surge in similar deals by several years.

1xBet has accumulated enforcement actions across at least 8 jurisdictions: a €400,000 Dutch KSA fine for unlicensed targeting, a UK Gambling Commission licence revocation, Indian Enforcement Directorate PMLA asset attachments, a Liberian court-ordered shutdown, and Ukrainian sanctions. Reporting indicates continued operation via alternative domains, surrogate sports-news sites, and out-of-home ads despite bans.

ANCHOR — Twitch banned streaming of gambling sites offering slots, roulette, or dice not licensed in the US (naming Stake, Rollbit, Duelbits, Roobet), while continuing to permit sports betting, fantasy sports, and poker streams. This policy split directly caused the migration of gambling streamers to Kick, the current driver of streamer sponsorship economics.

Describes crash games (Aviator, JetX, Aviatrix) as India's fastest-growing casino category, driven by India's smartphone base and tolerance for low-bandwidth play (3-4 Mbps). Cites 2022 data showing one crash producer's active-user share rose 450% over ten months, and Spribe saw a ~194% popularity jump within two months that year.

In contrast to the Western meta-analytic literature, this China-focused study found only a weak association between gambling engagement and loot-box expenditure, and found players broadly supportive of mandatory probability disclosure and pity-timer mechanics as fairness measures rather than experiencing them as exploitative.
