Vaidman described how a team of three players, each of them isolated in aremote booth, could use a three-qubit Greenberger-Horne-Zeilinger state toalways win a game which would be impossible to always win without quantumresources. However, Vaidman's method requires all three players to share acommon reference frame; it does not work if the adversary is allowed todisorientate one player. Here we show how to always win the game, even if theplayers do not share any reference frame. The introduced method uses a 12-qubitstate which is invariant under any transformation $R_a \otimes R_b \otimes R_c$(where $R_a = U_a \otimes U_a \otimes U_a \otimes U_a$, where $U_j$ is aunitary operation on a single qubit) and requires only single-qubitmeasurements. A number of further applications of this 12-qubit state aredescribed.Comment: REVTeX4, 6 pages, 1 figur
