Hamsterz Life is from the Petz series from Ubisoft for the handheld systems. Being released after Petz 5, it is part of the second Petz series. Hamsterz Life lets players to raise several breeds of hamsters and build fully customizable homes for them to live in. Just as in the other Petz games, players can interact with their hamsters by training, playing with, and feeding them.
At the start of the game, players can select their first hamster and name it. The hamster will then appear in a cage and be ready to play. Various actions can be chosen including training, feeding, care and other options. Training consists of teaching the hamster words (which they repeat back in their own hamster speak) by speaking the set phrases into the DS microphone. The hamster can repeat these phrases back, but inaudibly. Players can clean the cage and brush their hamsters. Hamsterz Life also includes many mini-games to play. Players can only have one hamster at home at once, any other hamsters that are owned are left with a girl with hamster ears until the player wishes to switch. The player's hamsters can visit with the hamsters of friends who also own Hamsterz Life. When playing mini-games, if players win, they receive prizes such as food or toys. Players can also let their hamster out of its cage to play in the surrounding room. There are present boxes in the room, which contain prizes they receive when their hamster finds them.
