It is shown that the weak phase γ≡arg( -VudV* ubVcbV*cd) can be determined using only untagged decays B0/B̄0→DKS. In order to reduce the uncertainty in γ, we suggest combining information from B±→DK± and from untagged B0 decays, where the D meson is observed in common decay modes. Theoretical assumptions, which may further reduce the statistical error, are also discussed.
