Difficulty modes

There are three different difficulty modes.  The tutorial mode is called 3x3:

It's called this, because there are three different categories of thing you need to figure out (people, house colors fruit, and drink), and each category contains three things.  This is a good starting point for any puzzler, but once you get used to it you can move up to 4x4 and the much more difficult 5x5 or 6x6 grids.  In these modes, there are more houses and each contains more things you need to place.  So in addition to which person, house color, fruit and drink, you will also need to figure out which pet goes where and which type of fish.

In all of the difficulty modes, however, it is completely possible to figure out the whole puzzle based on the clues you're given, so don't be afraid to try something more difficult!
