Totomi is a very strange game, the idea is to stack blocks on top of each other and build long chains of totems. Unlike other block matching game, the blocks don't just have to be the same colour or type. In Totomi all the blocks are animal based and understanding the game is about understanding the animals.
The game won't let you just stack one column of one type of animal for very long. You can build chains based on which animals like each other (eg dogs and wolves) or a rather more sinister food chain approach (eg cats and birds). You only have three columns to build on so you do need this approach to give you some choices to create a long chain.
