Raid sur Tenere (F) (1985) - Amstrad CPC - Strategy, War.

You are taking part in a rally across the African desert, but first you'll need to obtain money. You must select three sponsors and answer various questions, most of which require some quick mental arithmetic. If you obtain enough money, you must then buy a vehicle, fuel and supplies to keep you going. Once you're off, you drive across the desert, steering your vehicle left and right to dodge the obstacles and stopping every so often to rest.
