We compile this list using the USA region Wii Shop channel, so if you live elsewhere your list will probably be quite a bit different. Please feel free to post your region's findings below as always.

N denotes a new entry
No real surprise that World of Goo is once again in the #1 spot, although we did see My Aquarium jump over Tetris Party for the #2 spot, which is a bit surprising.
The big climber this week is once again Space Invaders Get Even which climbed four more spots to #4. Is it possible that we might see this game supplant one of the big three next week and put an end to their chart-topping dominance? Guess we'll just have to wait and see. The big dropper this week was Sudoku Challenge which fell four spots to #11.
As usual the newest entry in the Strong Bad series jumped up on the charts in a hurry, but we'll have to wait and see if it can manage a bit more staying power than its predecessors were able to after dropping off the charts fairly quickly. We also saw last week's stinker Hockey Allstar Shootout grab the last spot on this week's chart at #20. Some readers might remember that this title earned WiiWare World's first 1/10 rating. We're anxious to see how far up the charts this title will make it. Pong Toss has certainly managed to do quite well despite a very low rating.
