A logic game from the Tetris/Puyo Puyo series, brought over by the Brazilians from Game Gear (where, in turn, the game was moved from a slot machine). Two types of blocks fall from above - on some different animals are drawn, on the other - the food they eat. The goal is to build as long as possible a chain of identical blocks with food (the rules are the same as in Puyo Puyo - i.e. it is not necessary to build in a line, the whole continuous chain is considered) and end it with a block with the image of the corresponding animal, then the whole chain disappears, and you a certain number of points are awarded. The more successfully you play, the more problems the computer opponent has and vice versa.
The game is pretty good, like Tetris, but the rules are completely different. There are eight types of blocks in total - 4 with animals and 4 with their food. Guess what needs to be done. That's right... The animal eats its portion of food.
And now the plot: the zoo is looking for a new owner, so that he conscientiously watches over the animals. To achieve this, the applicant must pass many tests. The graphics, I want to note, are excellent, take a look at the year of release; I'm not sure about the sound.
