WikiTrail is a very addictive game!!
The objective of the game is very simple. Just get to the goal as fast as you can.
When you start a new game the app will randomly assign a start page and a goal page from wikipedia. All you need to do is to try to reach the goal by simply using the links in the page.
Try it on your iPhone or iPad now!!
It is even more addictive if you compete with your friends!!
