Digimon Masters Online is a free-to play massively multiplayer online role playing game in the world of the Digimon media franchise, namely the anime and the virtual world based on that of the cartoon. The game is free to play, and is one of several free games on Windows 7 and Windows Vista, and other Windows mobile devices. In essence, it's a browser-based game where you create your own avatar and wander around the digital world in order to collect Digimon and battle rival Digimon. It's similar to the old Tamagotchi games, but it's more expansive because it requires you to interact with the Digimon world.
If you're familiar with the Tamagotchi games, you'll find that this one has a few things in common with them. The most obvious is that you can do battle and even teach your pet Digimon to do a variety of different things. You can also purchase items from the shop which will give them additional abilities, or you can learn new skills for the sake of powering up your Digimon. However, one important difference is that, in this game, you are allowed to choose whichever Digimon you want to keep - and this is an important part of the gameplay.
If you don't like the notion of having to keep an account across several platforms, and would prefer to do everything in one place, you can opt for the Windows Mobile version of the game (with the help of Microsoft's SDK) instead. With this version, all of your data is stored on the memory, and you can access it using the Windows Mobile phone's default dialer application. There are also many differences between the online and mobile game play, such as the fact that you can use several Digimon with one account. This is another way that Tamagotchi can be played while you're waiting for your other mons to evolve. Regardless of what type of Tamagotchi you choose, you can rest assured that you're making the most out of this addictive game.
