The Stampede

We've all seen at events, these little stands having a stamp and you collect five of those by doing some task and then get to the end, to get a prize. The Stampede is just that. There is a play on words in the title as well. So, there will be 4 stands with tasks, increasing in difficulty of course, and should you complete the task, you will get a stamp. If you successfully collect all of the stamps, you get a prize at the end, or maybe play another game to win that prize as well.
