Codenames is a popular word-based party game for two teams, and this online version lets you play it with friends wherever they are. All you need is the game room and a voice or video chat to talk to each other.
A grid of word cards sits on the table. Each team has a spymaster who secretly knows which words belong to their team's agents. On their turn, the spymaster gives a one-word clue plus a number, such as "Ocean: 2", hinting at that many of their words. Teammates then guess which words the clue points to. Guess right and you reveal your agents. Guess wrong and you might help the other team, or worse, uncover the assassin and lose instantly. The first team to find all its agents wins.
