"Everyone starts with the exact same 10,000 — so why do we end up split into rich and poor?" Each day two random people meet and swap 1,000 on a pure 50:50 flip, with no skill involved at all — yet over time wealth piles up in a few hands. This simulator lets you watch it happen.
The rules are simple. Everyone starts with the same 10,000, and each day two random people meet and play rock-paper-scissors — the loser gives 1,000 to the winner. Even though outcomes are pure chance with no skill difference, inequality emerges, shown to you in live graphs.
Watch wealth tilt to one side in real-time animation, with bars re-sorted by rank each round.
Inequality captured in a single number — see how the Gini rises as time goes on.
What share of total wealth the top holds, plus richest/poorest assets and the number of bankruptcies.
Compare the line of perfect equality with the actual distribution to see the inequality area.
Freely choose participant count (50–500) and run speed to experiment with different conditions.
Save results and compare them with earlier runs — vary the conditions and spot the patterns.
All amounts in this app are virtual numbers for illustration and have nothing to do with real economic activity. There's no sign-up and no collection of personal identifiers, and experiment data is stored only on your device. The simulation is an educational model designed to convey the principle of inequality intuitively, and does not reflect every factor of the real economy.
See the inequality that arises even under fair rules — try it now. No sign-up, use it the moment you install.
