Here's an adventure game that requires some mathematics to progress! You play the role of the leader of an expedition whose goal is to reach the top of Mount Everest. You'll need help, of course, and this is got by bringing along sherpas, supplies and equipment.
Everything costs money these days, and the sherpas are charging on a daily basis. Not only that, but you only have £1,000 to start with, and the blighters need feeding every day!
Once the game is loaded, you are presented with a list of sherpas' names, together with their daily rate and strength ratings. They do seem to have a degree of British upbringing, with names like 'Tom', 'Keith', 'Jim', and so on.
Once the sherpas have been hired, a list of equipment is displayed, with items such as radio (always buy it), tent, oxygen, and so on. Some of the equipment will be essential, some not.
You then have 20 days' trek to the summit, which is measured in half days. At night, you can set up camp, and if you choose, establish one of three base camps where you can leave sherpas, equipment, and supplies before moving on.
In reality though, you'll probably run out of cash and your sherpas will desert back to the village. To continue, you'll have to descend to the village, where hopefully there is a donation waiting for you fur succeeding in your climb.
This game requires you to find the right combination of sherpas, supplies and equipment and so face the hazards ahead. A real challenge.
