Sumdog is maths. You have to answer questions as quick as you can. You can join classes in your school or play against  people in other schools. There are 8 maths games to play. My favourite game is the tower block. I like the tower block game because  if you get the right answer  you jump up a block.  There is a shop you can buy clothes to put on your sumdog characters. We are paying for the shop to open in school time.
