On the World Education Games Website we can see the following message:
The World Education Games will be taking a break in 2014 from official competition and will return in 2015. Watch this space for news on events that will take place in 2014.
If you enjoy games of this kind Sumdog and Tutpup are free all year round. For other free Number games see this page also this page on games collections; the collections from Math Playground and that from Oswego City School District are particularly good for mental arithmetic. For practise at tables, including against the clock see this collection.
