About this game

āš”ļø ARE YOU A FARMER OR A FIGHTER?

In this fun new idle role-playing game, youā€™re both, with sidelines in mining, crafting, construction and management too. In fact, youā€™re a king, with a kingdom to protect, expand and develop, and if you want to succeed thereā€™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.

šŸ‘‘ ARE YOU WORTHY OF THE CROWN? šŸ‘‘

šŸ›”ļø 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.

šŸ—”ļø ā€¦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.

šŸ¤“ Head for the longboats: Time management and resource mining arenā€™t enough: a great king has to prove themselves in battle. So, once youā€™ve taken care of your subjectsā€™ basic needs, earned coins and upgraded your army, sail off to war, raiding over 90 enemy towns and castles for plunder and XP.

šŸ° 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 youā€™re out of the game.

ā›ļø By royal command: Of course, a king needs soldiers, but youā€™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.

šŸ’£ 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 whoā€™s king of the castle!

šŸ”„ ARE YOU READY FOR A ROYAL ADVENTURE? šŸ”„

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. If you like the idea of role-playing as a hard-working, hard-fighting medieval monarch determined to build the biggest, fiercest, most prosperous kingdom, youā€™re guaranteed to enjoy King or Fail.

Failureā€”like boredomā€”just isnā€™t an option.

Early game is great. Late game is ad watch simulator. You cannot beat the combat levels without watching ads, which is annoying since I paid for no ads. What's worse is these ads crash, so after you've watched six in a row to load your ballista, the game crashes, the battle starts over, and the only reason you watched the ads is because you like ads, I guess.

I loved this game....til recent updates. Now, in order to upgrade your stuff, you have to have a crown, silver coins, and produce. You took away my plums and several buildings I had already finished building and upgraded to the max level til I upgraded. It's hard enough to make gold coins now that you added more šŸ’© we have to build up in order to grow. I love building games and this one was by far my favorite and please fix the battle part. It takes so long just to beat them and pass through.

Fairly fun. Heavy on the ads, though. My major complaint is the combat scaling. In later levels, with maxed out troops and ballista, some of the combats can take over an hour. Longer if you don't play ads to get more shots with the ballista. After a couple of days of every combat being over an hour (and more than one being over 2 hours), I quit. I'm uninstalling the game. Fun as it is, it's not worth playing for several hours just to win one combat.
