  The worst-case Lipschitz constant of an $n$-player $k$-action
$\delta$-perturbed game, $\lambda(n,k,\delta)$, is given an explicit
probabilistic description. In the case of $k\geq 3$, $\lambda(n,k,\delta)$ is
identified with the passage probability of a certain symmetric random walk on
$\mathbb Z$. In the case of $k=2$ and $n$ even, $\lambda(n,2,\delta)$ is
identified with the probability that two two i.i.d.\ Binomial random variables
are equal. The remaining case, $k=2$ and $n$ odd, is bounded through the
adjacent (even) values of $n$. Our characterisation implies a sharp closed form
asymptotic estimate of $\lambda(n,k,\delta)$ as $\delta n /k\to\infty$.
