  Rydberg electromagnetically-induced transparency has been widely studied as a
medium supporting light propagation under the action of nonlocal
nonlinearities. Recently, optical potentials based on moir\'e lattices (MLs)
were introduced for exploring unconventional physical states. Here, we predict
a possibility of creating fully three-dimensional (3D) light bullets (LBs) in
cold Rydberg gases under the action of ML potentials. The nonlinearity includes
local self-defocusing and long-range focusing terms, the latter one induced by
the Rydberg-Rydberg interaction. We produce zero-vorticity LB families of the
fundamental, dipole, and quadrupole types, as well as vortex LBs. They all are
gap solitons populating finite bandgaps of the underlying ML spectrum. Stable
subfamilies are identified utilizing the combination of the
anti-Vakhitov-Kolokolov criterion, computation of eigenvalues for small
perturbations, and direct simulations.
