In this work, we investigate the $\phi$--$\Gamma$ tapping curve in the steady state for monosized regular polygons with different number $N$ of vertices; from triangles ($N=3$) to icosagons ($N=20$). As the number of vertices grows, we expect polygon packings to approach the properties of disk packings. Since depending on the number of vertices these particles may or may not tessellate the plane, we also expect strong deviations from the general trends for some grain shapes. Finally, we compare the general features found in the $\phi$--$\Gamma$ curve of disk packings with those of regular polygons. Although some general trends are conserved, new phenomenology emerges.
