This plays like Uno with a passport stamp — match the color or number of the top card, use special cards to skip or reverse opponents, and race to empty your hand first. You can play against the computer or get matched with real opponents online, and the game cycles through different visual backdrops as a light theming touch. The rules are simple enough to learn in one round, which is really the whole appeal of this genre. It works fine solo against AI if you'd rather not wait around for a match to fill.
