We prove an asymptotic Lipschitz estimate for value functions of tug-of-war games with varying probabilities defined in Ω ⊂ R n . The method of the proof is based on a game-theoretic idea to estimate the value of a related game defined in Ω × Ω via couplings.Date: June 29, 2018. 2010 Mathematics Subject Classification. 91A05, 91A15, 91A50, 35B65, 35J60, 35J92.
