Reptile tank how to play

About Reptile Tank, from BoardGameGeek:

Reptile Tank is drafting tableau-building game designed and illustrated by Michal Peichl. It's for 1 to 6 players, ages 8 and up and one game lasts between 20 and 30 minutes. In Reptile Tank the players draft the cards with various species of lizards, snakes and tortoises and place them in the grid - the eponymous Reptile Tank. At the end of the game, once all grids have been completed, the players will count their points and check who has made their reptiles the happiest. In addition to the animals the players are also placing the environment cards – stones and herbs and if some card doesn't suit their intentions, they can flip it to its water side and earn some points this way. -description from the publisher
