Gerrit Noordzij writes about Ruse:
Ruse is remarkably extensive and complete. From 000 to 100 the family is divided into 11 variants of increasing contrast. Each variant contains six different kinds of figures (hanging proportional, lining proportional, hanging tabular, hanging proportional, superior and inferior) and a large number of ligatures. Prebuilt fractions are also included together with an OpenType feature that automatically composes fractions. The roman styles contain small caps as well. Any typesetting job for figures, whether it be in tables or plain text, can be carried out easily with Ruse.
