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.

This game is the utter description of what a Grind for All game feels like, coz yeah, Idle games are just to keep in your pocket and check them when you're bored. However this title takes that to a different level, because not only is everything unlocked by grinding, the shop doesnt allow you to buy things more than once. Which sucks, coz you might have grinded up enough to buy a new villain. Now you have to wait for tomorrow, then tomorrow the offer isn't there. Remove this feature please🙄

A fun, creative, and well thought out game. The mechanics are clever, the conversations you can eavesdrop on are always a joy to read, the characters' designs are wonderful, and the music is stellar. I adore the pixel art choice, and I love the jokes. This game takes itself the right amount of seriously, by that I mean it does everything incredibly well while making this game playful and a joy to have. I appreciate, though it may take a while, the option to unlock characters by working hard.

I've been playing this game for a long while, I've almost beat it. The pacing is almost perfect, if you save all of your green Crystals, you well get your next villain exactly when you need them, the dialogue is witty and surprisingly the main way you learn about different characters. I would recommend this to anyone. My only problem is that getting into evil eye is a bit annoying, but manageable.
