  A tiling of a topological disc by topological discs is called monohedral if
all tiles are congruent. Maltby (J. Combin. Theory Ser. A 66: 40-52, 1994)
characterized the monohedral tilings of a square by three topological discs.
Kurusa, L\'angi and V\'\i gh (Mediterr. J. Math. 17: article number 156, 2020)
characterized the monohedral tilings of a circular disc by three topological
discs. The aim of this note is to connect these two results by characterizing
the monohedral tilings of any regular $n$-gon with at most three tiles for any
$n \geq 5$.
