We develop the stochastic Perron's method (see e.g. arXiv: 1212.2170) in the framework of stochastic target games (arXiv: 1307.5606), in which one player tries to find a strategy such that the state process almost-surely reaches a given target no matter which action is chosen by the other player. Within this framework, the stochastic Perron's method produces a viscosity sub-solution (super-solution) of a Hamilton-Jacobi-Bellman (HJB) equation. Using a comparison result, we characterize the value as a viscosity solution to the HJB equation.
