There is no limit in the rules to how many you can have in a team. We have had many teams of one, and even whole class teams of 30 or so in the past. We don’t mind. Prizes have to be shared of course, and we do have to ration tickets to the prize-giving ceremony as well, but if you work best in a large group or have diverse and complementary skills then you are very welcome. We have team prizes as well as individual and we look forward to seeing what you can do.
