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.

I understand this was supposed to be a fun game, but I find it boring. Even though there are different villains and some features added, I feel that something is missing. All day, I just rotate in the city, and that's kind of boring. I wish something could be different, like a 2D story of a villain attacking the city—something cinematic, with a group of bad guys attacking the city or a single villain. Each cinematic story could have different actions and endings.

Fun idle game. Unfortunately progression relies on hard to get materials, and spending them wisely. If you don't you will get to a point where you can no longer progress until you grind those hard to get materials. The green gem things are the most difficult to grind and you need a lot of them or spend money, it's possible to grind them via daily missions but it'll take awhile. Other than that it's fun, silly, and an overall great time killer. Just a little grindy at times.

I tried this game because I liked their others, but I didn't find this one nearly as fun or engaging, and it has some really unsatisfying game design choices. There is very little to do when you log in, even for an idle. They also lock players out of claiming event rewards if the event ends before you claim them. Absolutely infuriating since you have to spend hard earned currency to get anywhere in them.
