Sligoil is a monospace typeface. It has been designed for the interface of the Unknown Number game, published by Godolphin Games. Sligoil is also the name of an evil fictional company within the game.

The Sligoil typeface has been influenced by the culture of the British isles (the work of Matthew Carter, of course, but also signs on Irish whiskey distilleries) and also by the letters on vintage Space Cadet keyboards (produced by the MIT). It presents wide language support for Latin-based European languages and a collection of symbols and alternate forms (including upright italic letters).
