  I demonstrate that one can detect pixel gravitational microlensing events at
the rate $\sim 180\ {\rm events}\ {\rm yr}^{-1}$ and that some fraction of
events ($\sim 15$) will be good enough to measure time scales at the $20\%$
level if the experiment is carried out toward the central M31 bulge region with
a dedicated 1 m telescope and a $2{\rm K}\times2{\rm K}$ CCD. I also show that
the event rate could be significantly increased (up to a factor 6.5) if more
aggressive observation strategies are adopted. These aggressive strategies
include multiple observation sites, using a bigger telescope, and reduction of
seeing differences among images. A few years of observation could provide a
data set big enough to extract important information about the M31 bulge such
as the optical depth distribution, the mass spectrum of M31 MACHOs, and the
luminosity function, which currently cannot be obtained by other methods.
Additionally, I find that the extinction of M31 bulge light by dust in the disk
is {\it not} important and can be approximated by the model in which only
$20\%$ of light in $V$ band is extinguished over most of the bulge area.
