HAO788 is an online gaming platform that organizes its multiplayer catalog by how players interact, helping users find games that suit their preferred style. Its main modes include team play, where players coordinate across different roles; one-on-one duels focused on quick contests; cooperative missions against the game system; and free-for-all arenas. Games span strategy, action, sports, card and board games, and casual play. Catalog entries include player-count labels, mode information, and estimated round lengths, with filters to help users choose a game for a pair or a larger group.

The catalog is available through the website and a mobile app, with the same account and game collection across devices. Visitors can browse without registering, while joining sessions and saving progress requires an account. HAO788 also provides official alternative access links, customer support available 24 hours a day, and in-game purchase options including QRIS, GoPay, DANA, and BCA transfer. The platform says it updates its catalog regularly and applies consistent mode and player-count labels to new games.
