It first launched with 5 game modes: 1v1 Mystery Duel, 3v3 Elimination, 6v6 Mystery Heroes, 6v6 No Limit, 6v6 All Brawls! The Arcade was also updated to include the Game Browser, where players can create and join custom games with tailor-made rules. However, the Game Browser has since left the Arcade, and is currently a separate entity from it.
In addition to those modes, seasonal events' brawls and game modes will replace some Arcade mode in the time of an event.
Only 5 gamemodes are active at any given time. Arcade gamemodes rotate weekly, with the exception of the gamemode in the top-right slot marked with "Changes daily", which consistently changes every day at 00:00 UTC, as well as the gamemode in the bottom-right, which rarely changes.

Players can earn up to three Loot Boxes by winning any Arcade game modes. These boxes are rewarded after the 3rd, 6th, and 9th win. The count is reset at 00:00 UTC every Tuesday.
Furthermore, whenever a new Arcade game mode is added in to the Arcade, including Seasonal Events, players can also receive a Lootbox upon winning that game mode for the first time.
- If the player hovers over the Arcade mode option, a piece of music that resembles the one used in the arcade for Hanamura will jingle.
- Coincidentally, a remix of Heroes of the Storm's theme can be heard.
