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.

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.

Overall a solid gameplay loop without the ads being too intrusive. You choose when to view ads, nothing is forced on you as the player. The rewards for a 30 second ad are pretty decent however. The idleness works well and the active gameplay parts are fun. There is the option to deactivate ads for 9.99 forever, but that honestly feels too steep. Would have insta bought that if it was at 2.99-3.99. possibly 5.99

I enjoyed the game. It had a clever charm that kept me engaged... then the game lost my data. Twice. Both times just as I started the Evil Eye progression. It's disconcerting, especially after having paid for the ad free option, and the fact that their Idle Apocalyose game doesn't have this issue. Maybe I'll check on it later to see if the bug gets fixed, but for now the sudden loss of effort isn't worth it.

What's new

+ Added the “After the Grand Plan” City Theme. This City Theme is a wasteland set after the supervillains have executed their plans. You can buy it from the shop and it gives a +300% Infamy bonus.
+ Reduced the cost of replaying a random event for Evil Eye currency from 5k Corruptonite to 3k.
+ Other tweaks and bug fixes.
