You might remember Ethan Nicholas, who epitomised the App Store gold rush when his artillery game iShoot supplied him with a swimming pool filled with flourescent Champagne and a Bentley made of solid caviar. Or thereabouts.
Well, Ethan has taken his time in setting up Naughty Bits software studio and preparing his follow up game, which just just hit the App Store. Rhumb Line takes its name - and its concept - from the path defined by taking a compass bearing relative to true north.
The game began life as a boardgame, and requires you to take turns positioning stones on a circular playing area to complete arcs, radii and spirals of four or more stones. There's a two player mode and a few different difficulty levels when playing against the CPU.
