*p < .05, **p < 01 for the 1-tailed test of a pre-registered one-sided hypothesis (otherwise, p-value is for the 2-tailed test). N=4120 observations. Linear regression estimates with robust standard errors adjusted for clustering at the participant level (n=206 clusters). Skill-games were considered to be the following: blackjack, poker, sports betting. Non-skill-games were: slots, baccarat, craps, roulette
