Idle Heroes

Idle Heroes from DHGAMES is a fantasy squad RPG built around the idea that your team keeps improving even when the phone is in your pocket. The journey runs from Sara Forest to the High Heaven, with heroes pushing through ancient ruins against forces of darkness.

The idle system is the hook: heroes train while the player is away and return stronger, which cuts down on grinding. The roster is large, with over 400 heroes split into factions, each with particular skills. Heroes are summoned and trained, or broken down into Spirit material to evolve others, and gear can be forged to equip the team. Content is plentiful, including battlegrounds, dungeons, quests, towers and an arena. Guilds form a big part of the social game, with guild wars over a floating continent and multiplayer boss battles, while the worldwide arena lets heroes fight other players' teams for a spot on the leaderboard. The developer notes that storage permissions are requested because of video ads.

Ratings are excellent: roughly 1.1 million average 4.7, with 82% five stars and just 4% one star. It has 10,000,000+ installs. The Play record lists no ad support, and in-app purchases range from $0.99 to $99.99 per item. The latest update came on 2026-09-02, it needs Android 6.0 or newer and is rated Everyone 10+. The download is a big one: we list 29 versions, and the newest, 1.35.1, is 863.8 MB.

Players who like collecting and levelling a large cast with little hands-on grinding will find a deep game here. Those short on storage should check space first, and anyone wary of gacha-style spending should be cautious.
