Idle Trillionaire

Idle Trillionaire is an idle card game about starting with a lawn-mowing job and building wealth until you become master of the known universe. As your earnings reach billions per second, you try to save up for cards costing $1 trillion and confront the madness that comes with pursuing immense wealth.

Cards and happiness

You scroll through and click cards, with over 600 hand-written cards containing shock or humor. You earn and spend happiness points to unlock new cards; if your happiness drops too low, something bad might happen. An in-game deck editor lets you create mods and share them with the community.

Beyond a trillion

As a trillionaire, you can buy countries, continents and the entire globe, and commit trillionaire-style atrocities as you pursue dominance and succumb to greed.

Prestige and achievements

After getting the Global Domination Card, you can prestige. Each prestige increases the time rate and unlocks new cards on subsequent playthroughs. You will need to prestige many times to “Break the Universe.”

The game tracks achievements, including milestones for having more money than other players at the one-year mark and other points in your progress.
