Heroes of Might and Magic Mini was a turn-based browser game that was released in April of 2006. Featuring artwork from Heroes of Might and Magic V, it was meant to get fan attention before the main game's release in May that same year. In order to drum up excitement, they arranged tournaments for players, with prices including limited edition copies of Heroes V.
The game featured six factions, the same factions as Heroes V, and ten creatures for each of them. Players would hire creatures and fight each other, similarly to an ordinary Heroes V battle, but the game featured no town building.
The game was located at www.heroesmini.com. While the site has since disappeared, it is still visible in web archives.
