About this game
Idle Trillionaire is a game about becoming a trillionaire. You are a seemingly normal person, but how will that break your fragile human mind when you are earning billions each second and realize madness is closer than your dreams of a trillion?
Start out with a lawn mowing job, and end as the master of the known universe.
New: You can now create your own mods with the in game deck editor, and share them with the community.
Over 600 hand written cards and a prestige system that increases the time rate and unlocks new cards on subsequent play throughs.
Doom Scroll and Click Cards
Every card is lovingly written and full of shock or humor.
Feel How Huge $1 Trillion Dollars is
Even when you are earning millions a second, saving up for that trillion dollar card will take you forever.
Don't Die, Stay Happy
Accumulate and spend happy points to unlock new cards. Be sure not to let your happiness drop too low.. or something bad might happen.
Beyond Trillions: While $1 trillion is an astronomical sum, your ambitions don't stop there. As a Trillionaire you dream bigger. Purchase entire countries, continents, and even the entire globe and commit trillionaire style atrocities as you solidify your dominance and succumb to crippling greed.
Prestige Up after getting the Global Domination Card.
You will need to prestige many times to "Break the Universe"
