Let B be a real separable Banach space with the RNP and {Xn
n≥1} a sequence in L1B such that its subsequence {Xs
s∈S} is an L1-amart.We prove that {Xn
n≥1} is an L1S-game iff it converges in probability under the condition liminf E‖XSn‖<∞ or ∫{τ<∞}‖Xτ‖dP<∞
τ∈ where is the set of all stopping times with respect to {Fn
n≥1} and Sn=inf{s∈S:n≤s}
n∈N.This result extends and improves the corresponding results of Luu. The results of complete canvergence for arrays of random variables extend and improve the corresponding results of Hu et al.
