  Device-independent self-testing allows a verifier to certify that potentially
malicious parties hold on to a specific quantum state, based only on the
observed correlations. Parallel self-testing has recently been explored, aiming
to self-test many copies (i.e. a tensor product) of the target state
concurrently. In this work, we show that $n$ EPR pairs can be self-tested in
parallel through $n$ copies of the well known CHSH game. We generalise this
result further to a parallel self-test of $n$ tilted EPR pairs with arbitrary
angles, and finally we show how our results and calculations can also be
applied to obtain a parallel self-test of $2n$ EPR pairs via $n$ copies of the
Mermin-Peres magic square game.
