We have studied the Potts spin glass with two-state Ising spins and
s
-state Potts variables using a cluster Monte Carlo dynamics. The model recovers the
±
J
Ising spin glass (SG) for
s
=
1
and exhibits for all
s
a SG transition at
T
SG
(
s
)
and a percolation transition at higher temperature
T
p
(
s
)
.
We have shown that for all values of
s
≠
1
at
T
p
(
s
)
there is a thermodynamic transition in the universality class of a ferromagnetic
s
-state Potts model. The efficiency of the cluster dynamics is compared with that of standard spin-flip dynamics.
