Title : A framework for gacha psychoeducation: Building awareness in young people of gambling in mobile video games

The anticipation and rush that comes from wishing for a character in Genshin Impact is a feeling many gamers would be familiar with - lootboxes and gacha systems have become a dominant mechanism in games used by children and adolescents. It is said to have originated in 2004 in MapleStory via adaptation of Japanese gashapon vending machines, and then rapidly diffused into East Asian mobile titles and subsequently into the West [1]. Structurally, they operate via variable-ratio reinforcement schedules, whereby a player pays real (or functionally real) money in exchange for a randomised outcome; in the case of Genshin Impact, the variable is a maximum of 90 pulls for a 5-star, with grindable Primogem currency. Variable-ratio reinforcement underpins slot machines and strongly triggers reward and anticipation circuits in the brain [2]. Younger players are particularly vulnerable because developmental immaturity impairs probability reasoning, future discounting, and inhibitory control, producing gambling-like reinforcement in games without children recognising it as gambling [3].

In the UK, three in four of the highest-grossing iPhone games contained paid loot boxes in 2021, up from approximately 59% in 2019 [1]. Discrepancies in identification across studies suggest that prevalence may be underestimated due to hidden or bundled loot boxes and methodological differences [4]. This prevalence means that children encounter gambling-like mechanisms in games they already play. Beyond structural reinforcement, gacha systems operate through ‘affective embedding’: aesthetic, parasocial, and identity-based attachments to characters and game-worlds that alter cost-benefit cognition. Players can often spend because it feels like “taking care of the character” or “showing loyalty,” not because they rationally evaluate probabilities or cost [5]. This relational mis-labelling is especially relevant in child mental-health populations, where attachment needs and emotional regulation are often therapeutic targets [5].

Lootbox purchase is associated with elevated odds of problem gambling independently of other gambling activity in Australia (12–17 years) [6], Japan (~14 years) [7], and the UK [3,4]. Spending is linked to psychological distress, depressive symptoms, and indebtedness [8]. A Frontiers study in an Italian adolescent sample found that lootbox engagement predicted both problem gaming and gambling before and during COVID-19 lockdown [9]. Together, these studies indicate that lootbox risk intersects gambling, gaming disorder, emotion-regulation, and developmental neurocognition, rather than being merely a literacy problem. CAMHS populations share relevant vulnerabilities which include impulsivity, rejection sensitivity, affective dysregulation, attention fixation in ASD, and screen-based self-soothing behaviours [3–9]. Psychoeducation targeting reinforcement mechanics and relational binding is therefore clinically relevant.

Methods: A two-phase approach is proposed: Phase 1 delivers psychoeducation to university anime and gaming societies (low-risk, developmentally mature analogue sample) with pre/post surveys in order to measure effectivness. Content includes the history of gacha games and loot boxes, dopamine and reward anticipation, in-game currency value distortion, scarcity for status loops, social comparison, parasocial bonding, and affective embedding [2,5]. Pre and post measures assess awareness of mechanisms, subjective ‘ability to stop’, beliefs about gacha game fairness, and relational attachment to characters.

Phase 2 adapts this educational content for CAMHS patients using drama therapy methodology. Gacha rolls are performative events - the ‘reveal’, the dramatic beat, and rarity promise - so drama therapy provides an embodied metaphor and non-shaming reflective container [5]. Phase 2 is co-designed with CAMHS clinicians to tailor materials to developmental stage and clinical vulnerabilities.

Results (anticipated / selection of curricular components): Phase 1 identifies curriculum items relevant for CAMHS psychoeducation: recognising “when to stop”; understanding biological reinforcement; distinguishing engaged play from gaming disorder; scarcity-induced status anxiety; parasocial attachment and identity; emotional decision distortion in relation to characters; and time-as-currency (farming/grinding as probabilistic stake) [2,5,6,9]. These map onto both structural gambling-like risk and affective embedding, compatible with CBT-style psychoeducation and drama-based reflective work.

Discussion: Loot boxes are gambling-like mechanics without social signals of gambling. Children cannot legally enter casinos, but a casino contingency can enter a child’s bedroom via content drops, wishes, or gacha banners [3–5]. Evidence shows high prevalence, consistent associations with gambling and problem gaming, psychological distress, and affective embedding that bypasses rational cost–benefit evaluation [1–9]. Prevalence data from UK studies highlight that even games previously considered “safe” may contain hidden loot boxes [4]. CAMHS populations are disproportionately vulnerable. Psychoeducation — especially when embodied in drama therapy — may enable earlier recognition of risk and self-regulation before addictive trajectories consolidate.

Limitations include Phase 1’s non-clinical, self-report sample; causality uncertainty due to cross-sectional designs; and UK-specific CAMHS trials yet to be conducted. Nonetheless, the convergence of neurobiological, epidemiological, and cultural evidence justifies this preventative intervention. Future research should examine longitudinal outcomes in clinical populations, the impact of parasocial and affective embedding, and interactions with comorbid mental health conditions.
