I know the age range for this game is 7 and above but it is a very easy game for younger children to pick up and play. My 4 and 6 year old boys were able to jump straight in and play it with no issues at all. The levels are easy to complete with big arrows pointing to the next bit that needs doing. Be aware that this is a kids game and very easy, if you are looking for a challenging game then this is not for you. On the other hand, if you after achievement point then this is a very good game for collecting the 1000.
Only negative point about the game is that there are 6 worlds to play across. The first one is open for you but progress to the next one you need to have collected 2000 gold. It took my boy 2 run throughs of the first world to do this.
