Climb the High Tatras from the valley and the forest gives way to dwarf pine, then to bare rock below Gerlachovský štít, at 2,655 m the highest peak of the Carpathians. Every app sold on +421 sits at the altitude its rate earns: the summits at 50% or more, dwarf pine at 20 to 49%, the forest under 20%, the valley floor for apps with too few recent orders to measure. 19 of 112 apps have a measured rate.

Is a Slovak number the best route, or is a neighbour better?

Slovakia makes wine in six regions, from the Small Carpathians above Bratislava to its own corner of Tokaj. Pick an app from the wine list and two glasses are poured: Slovakia’s and the best of Czechia, Austria, Hungary, Poland, Germany and Romania, each filled to its delivery rate. A missed code is refunded, so the fuller glass wins; when the two are within 10 points, the cheaper one does. Slovakia wins 6 of 13 tastings.

Slovak tinkers, the drotári, once walked across Europe mending pots with wire; on this map a wire runs from Slovakia to the country where each app’s code lands. Pick a wire.
