How does Finance Lab work?

Pick which topics you want in the rotation at the top (candlesticks, Greeks, valuation). Each round draws from one of your enabled topics and asks a multiple-choice question. The first wrong answer ends the streak.

Why was this merged from three games?

The three former games (Candlestick Patterns, Options Greeks, Stock Valuation) all shared the same MiniGameShell, the same difficulty curve, and the same round shape (read a prompt · pick the right label). Splitting them into separate landing pages was taxonomical noise; merging gives the player one place to build a finance streak with the topic mix they prefer.

Can I lock to one topic?

Yes. Toggle off the topics you don't want and only your chosen topic appears each round. All three are on by default; the picker remembers your last selection.

What is a candlestick pattern?

A candlestick shows the open, high, low, and close price of a session as one bar. Patterns are recurring shapes that traders use as short-term signals · Hammer suggests a bullish reversal, Shooting Star a bearish reversal, Doji indecision, Engulfing patterns a directional follow-through.

Risk sensitivities used by options traders. Delta is the price hedge ratio. Gamma measures how fast Delta changes. Theta is daily time decay. Vega is sensitivity to implied volatility. Together they describe most of what moves an option price.

How do valuation ratios work?

A ratio like PE (price ÷ earnings) is meaningless on its own. The game shows each ratio against an industry benchmark so you compare against context · a tech-stock PE of 30 might be cheap; a utility PE of 30 is nosebleed-high.

Are the rounds the same for everyone?

Yes when handed the same seed. The game is fully deterministic · same seed produces the same prompt and the same option order. Useful for classroom drills and shared deep-links.

Yes. PlayMemorize is a Progressive Web App. Once installed, Finance Lab works without an internet connection.

FAQ

About PlayMemorize Finance Lab

Finance Lab is the merged finance trainer. Three topics share one landing page and one streak · candlestick patterns, options Greeks, and stock valuation. Pick which topics are in the rotation at the top of the page; the engine pulls from whichever subset you enable.

Candlesticks topic. Each round shows an OHLC (open-high-low-close) candlestick and asks you to pick the pattern name · Hammer, Shooting Star, Doji, Bullish Engulfing, Bearish Engulfing. The classic vocabulary every technical trader uses to read short-term price action.

Greeks topic. Each round presents a market scenario ("the stock moved +1.00, the option moved +0.55") and asks which Greek explains it · Delta, Gamma, Theta, or Vega. Conceptual rather than computational · the focus is on knowing which sensitivity is at play, not calculating it to three decimal places.

Valuation topic. Each round presents a company's valuation metric against an industry benchmark and you judge whether the stock is undervalued, fairly valued, or overvalued. Three metrics covered: PE, PS, EV/EBITDA. Trains the habit of comparing to context rather than memorising absolute thresholds.

One streak across all enabled topics. Each correct round adds to your streak; one mistake resets it. Toggle individual topics off to drill one shape (full candlestick library, all Greeks, deep valuation work), or leave all three on for a polymath gauntlet of finance fundamentals.

Part of the PlayMemorize family of brain-training games. Runs entirely in your browser, works offline as a Progressive Web App.
