This paper analyzed the impact of two gamified distribution methods of coupons ( namely games of chance and games of skill) on consumers' intentions and behaviors of coupon redemption. A cognitive -emotional dual-path theoretical model is proposed to account for the underlying mechanisms. Across two field experiments and one online experiment, we found that compared with directly-delivered coupons, coupons delivered through chance-based or skill-based games are more likely to be redeemed. These effects are mediated by perceived scarcity of the coupon and perceived enjoyment of the coupon delivery process. In addition, the impact of chance - based games on perceived enjoyment is mediated by perceived luck, whereas that of skill-based games is mediated by perceived effort. Our research contributes to the literature on coupon promotion and gamification design, and provides important guidances for the design of coupon promotions.
