The mechanics are simple and it is also not dependent on language. Basically each card can be used for personnel (labourers, engineers or scientists) OR as a facility of some type (university, mine, factory or enrichment establishment). First you must mine the uranium, then you must enrich it and then you can build bombs with the uranium you've stockpiled. A very clever game. No luck apart from the draw of the cards, so you must learn to play the cards you've got to the best of your ability. This game is also great fun SOLO, and the cards for use in a 2+player game have special text for solo play.
