User reviews

It’s got an Iron hold on me!

This game is awesome. Fun. Addictive as all hell. Really easy to pick up, but also hasincredibly deep up upgrade paths and styles. Plus quests! Who doesn’t like quests? (Cue the sound of crickets, because there is no one who doesn’t love a good quest!)

So much great in one package!

This is by far one of the best app games I’ve ever played. The game play, the build options, and the limitless nuggets waiting to be discovered make this a must-play. I wish I could give it six stars!

Response from developer

Really appreciate that, and how you said it, cuz there’s more “nuggets”coming after this week as well as the Veilwatch system, where new ways to execute a siege will happen.

For idle and dungeon lovers

Ironhold has made idle games fun for me again!

Candidly, I love a half-idle game where I can tune in every few minutes rather than once an hour - this game crushes it. The castle defense aspect scratches the itch of leveling and earning against a never ending hoard of goblins, dragons and orcs, but the cool part is capturing heroes.

While playing, heroes enter the field and you can capture different levels (common -> radiant) they can improve your tower defense in future rounds, but what I LOVE is that I can send them on quests at the beginning and end of my day.
This part is a completely idle way to earn which is way better than starting a tower defense before bed and waking up to losing at level 300 like I’ve done with games like The Tower.

To me this opens up a world of possibilities for grinding stones and gems and leveling up my heroes as well as my castle.

Would highly recommend this game and can’t wait to see it evolve the hero stories and side quests

Response from developer

Thanks so much, and the roster (character) system was the surprise feature I added before realizing it would be core to the whole game. And that will be a huge focus for the next few updates, with better feedback, branching quests, and an incremental system that flows out of the quests and dungeon. Also, dungeon bosses will matter very soon!
