Compound Idle: Money Tycoon

Start small. Invest wisely. Take Finn all the way to the stars.

Compound Idle is an idle tycoon game about growth, strategy and compound interest. Buy assets, reinvest your earnings and build a financial empire with Finn, from his first savings account to a galactic network.

20 ERAS AND 23 ASSET CLASSES
Stocks, ETFs, real estate, stock exchanges, orbital stations and lunar mines: every era opens new opportunities. Finn's workspace grows with your progress. Choose your next investments and discover milestones, strategies and permanent upgrades.

YOUR DATA CENTER FROM ERA 9
Income earned in the main world generates training data. Spend it on servers, improve data collection and increase your main-world income permanently. Data, servers and research survive cash-outs.

FINN'S INVESTING CAREER
After your first cash-out, open a separate portfolio with 1,000 game coins. Trade fictional stocks, follow sector trends, collect dividends and set automatic sell targets. Pass 49 fictional rivals as you climb from rank 50 toward the top. Your portfolio and main world stay separate. There is no real-money exchange or online leaderboard.

RECORDS MAKE YOU STRONGER
Every asset purchase costs more while production keeps growing. Beat your best run, then cash out for reputation and permanent income bonuses. Keep your current era and tap levels. Large strategies from era 11 can be purchased in four useful stages.

EARN DURING YOUR BREAKS
Your assets keep working offline. Start with four hours of offline earning time and extend it with upgrades. Optional reward videos can build an additional offline reserve of up to three hours.

MORE GOALS WITH FINN
Complete daily and weekly missions, claim daily rewards and discover 20 weekend stories with their own rules. Collect trophies, catch broker drones and explore gold boosters, Epic upgrades and ten piggy-bank stages.

PLAY AT YOUR OWN PACE
No separate game account is required for the main game. Reward videos are optional and only start when you choose. Optional in-app purchases are available.

Compound Idle uses fictional values. It offers no real-money investments or cash withdrawals. Company and brand parodies are for entertainment.
