Play Blocks puzzle zoo! Place the blocks on the field and connect them to the cages. Once connected the animals are free! You can earn 3 stars per level, each win also gives you trophy points and coins. You can see the status of the stars you can collect with the slider below the game, it moves inward with every piece you drop. Once you progress the levels will become harder and you must free multiple animals per level.
You can choose between 2 power-ups in this game: The hammer, this will hammer away a few blocks making room to place new blocks. And the bomb, when you use the bomb it will destroy a piece of the field, removing all pieces around it.
A good strategy to connect multiple animals is by sharing the blocks they can walk over. There is no need to make 3 paths if there are 3 animals. Just make 1 path and connect the last bits to all the different animals. The same counts for the keys, you can share the roads.
