Frequently Asked Questions
1. How do I win the game?
You win by correctly guessing which stock gained the most value on the last trading day. The answer stock is shown from the start with a gold background (or silver in practice mode), but its logo is hidden behind the Stocktangle logo.
2. What is the bomb and what happens if I guess it?
The bomb is the stock that lost the most value during the trading day. If you guess it, you instantly lose the game. The bomb is always shown in black on the treemap. There is no bomb in practice mode.
3. How often does the game update?
There is one new game per day, starting at midnight UTC (12:00 AM UTC). The game uses data from the most recent trading day when the stock market was open.
4. What stocks can I guess from?
The list varies by day, but it's usually the top 100 stocks in the S&P 100 index. If the game is based on the same market data as the previous day (because the market wasn't open), the list expands to a larger index like the S&P 500.
5. What does the colour of a stock mean?
The colour shows the percentage change from the previous trading day. Bright green indicates a large gain, while bright red indicates a large loss. The percentage is calculated using the difference between the market close value on the data date and the close value from the previous trading day.
6. What does the size of a stock mean?
The size of each rectangle represents the company's market capitalization (market cap). Market cap is the total value of a company's shares of stock. It is calculated by multiplying the price of a stock by its total number of outstanding shares. Larger rectangles mean more valuable companies.
7. What do the labels in the diagram mean?
When 2 or more stocks in the treemap share the same sector, they're grouped together with a label at the top. Stocks in the same industry within a sector are grouped even more tightly with a label at the bottom. Click on a label to filter the treemap to only show stocks in that group. Click the label again to clear the filter.
8. I already beat today's game. Is there a practice mode?
Yes! Practice mode lets you play unlimited games using the same market data as the daily game. You can choose which stock index to practice on (only smaller indices than the daily game are available). The answer stock is chosen randomly and shown in silver instead of gold, and there is no bomb. Start a new practice game from the profile page.
9. Where does the stock data come from?
All stock market data comes from the APIs provided by EODHD.
