About this game

Ever wanted to be the villain? To build a lair? Hire henchmen? Fight superheroes? Concoct dastardly plans? Raid a city? Or… take over the world?

No? What, really? Sure you do!

Idle Mastermind, from the makers of Idle Apocalypse, is the best supervillain simulator of 2020! Play as three supervillains. The techy but tiny: Dr DOS. The gangster crime boss: Yara. Or the unpredictable: LOL. Each has their own evil grand plan.

Build a lair to run your empire from. Hire a bunch of evil henchmen to do your bidding. Raid the city above to gain precious resources. Unlock new research and skills to improve your criminal, idle empire.

When you’re ready, execute your evil plan and bring about the apocalypse!

Play as 3 distinct villains, each with:
+ A unique lair with special floors and henchmen.
+ Different strategies, skills and stories.
+ Unique resource management styles.

Build your dream lair:
+ 30 unique floors.
+ Floors that will generate resources while offline.
+ Special floors with unique gameplay elements.

Hire an army of evil thugs:
+ 20+ henchmen.
+ Different classes, abilities.
+ Unique resource management gameplay.

On top of that it has all the humour and inane chatter of a Grumpy Rhino game. The makers of Idle Apocalypse.

Lovers of simulation games and incremental clickers won’t be able to put down this dastardly, near criminal RPG.

Very cool game. Nice gameplay, cute graphics and quirky sound. Would be so much better if they didn't go overboard with the microtransactions. Actually, it's more like macrotransacrions. I'd gladly pay a couple of bucks for a good game, but since they are so greedy I decided they will never see a cent from me. This also means that the game is no fun at all anymore after a couple of days. I just don't support this business model.

Overall I'm really enjoying it I've been playing a while now, I do have one question I'm not sure if it's a bug or if I just misread this costume description, after joining the evil eye organization I unlocked the costume for scrapper and it says it gives a 500 percent bonus if you put them in the city Dr Dos only, but the damage doesn't seem to go up
