Pop Penguin and the Place Value Race

This is an appealing  online Math Playground place value game (where you try to beat  Pop) that Richard Byrne shared recently in his blog. What I liked about Pop Penguin and the Place Value Race was both the simplicity (it looks like an old fashioned board game and is easy to follow) as well as its complexity (when asked to solve a problem, there are several options).  I think both these factors would keep students playing multiple times to increase their score ( how many coins you have at the end of the game) and to try and beat Pop.
