About this game

⚔️ ARE YOU A FARMER OR A FIGHTER?

In this fun new idle role-playing game, you’re both, with sidelines in mining, crafting, construction and management too. In fact, you’re a king, with a kingdom to protect, expand and develop, and if you want to succeed there’s a lot of work ahead of you.

Start with just a small squad of swordsmen and a few berry trees, then get working to build a city, feed your people, raid enemy castles for resources and experience, expand your army and turn your tiny village into a flourishing and fearsome empire.

👑 ARE YOU WORTHY OF THE CROWN? 👑

🛡️ Turn your swords to plowshares: Start the game farming berries, sell them at market to feed your hungry people and use the coins you make to invest in the development of your kingdom and your wars of conquest.

🗡️ …and your plowshares into swords: Spend the profits you make from crafting in this all-action RPG on expanding and upgrading your army, with five different types of soldier to recruit and improve. Turn your small band of raiders into a mighty horde of fiercely armed knights and archers, ready to conquer the known world.

🤴 Head for the longboats: Time management and resource mining aren’t enough: a great king has to prove themselves in battle. So, once you’ve taken care of your subjects’ basic needs, earned coins and upgraded your army, sail off to war, raiding over 90 enemy towns and castles for plunder and XP.

🏰 The builder king: Equip your town with new houses and facilities. The game has over a dozen different types of resources for you to craft into over 150 different new buildings and industries, from warehouses to taverns to luxurious palaces, that will also bring you idle profits when you’re out of the game.

⛏️ By royal command: Of course, a king needs soldiers, but you’ll also need a whole host of other workers to keep your kingdom and your idle income ticking over. Hire and upgrade farmers, woodcutters, miners and more to really make your craft empire flourish.

💣 Go ballista: Start every battle with a bang by using the ballista to hit the enemy where it hurts. Upgrade this powerful weapon to get access to ten increasingly destructive types of projectiles so you can really show the enemy who’s king of the castle!

🔥 ARE YOU READY FOR A ROYAL ADVENTURE? 🔥

Download King or Fail now and dive into an all-action RPG that combines crafting, conquest and world-building in a fun and addictive casual format.

I was really loving this game and everything was working perfectly for awhile. Then it started to not load properly. First the trees wouldn't respawn then I literally got stuck in battle mode and it wouldn't let me out or attack the last tower there. If this gets fixed then I'll keep it but if I can't play then there is no reason to keep it. It's level 19 that keeps messing up. Edit:I've waited to see if the problems were fixed or a reply but I never heard anything. Uninstalling.

I'm not gonna get into the fact that there are occasional ads that disrupt game play, every free game out there has them and that's never going to change. What bothers me is the fact that this game is so unfinished. Resources won't respawn and often get caught unable to level up because new leveling events fail to appear upon completing the last one. In addition, the progress your automatic resources make resets every time you close the game or go off to raid a castle.

Decent game. Needs improvements to everything speed wise. The fps is horrible, the loading time for pressing x or cancel is outrageous. Watching ads suck. What aggrivates me the most is the "would you like to restore your health" message is probably the number 1 cause of death for my character because it freezes my character during retreat from moving entirely and the load times just to move suck.
