The shift

Trading has gone from the few to everyone.

127m

people investing on India's National Stock Exchange, up from 30 million in 2020.

3×

more option contracts traded in the US each year than in 2019: 4.9 billion → 15.2 billion.

NSE (Jan 2020; 31 Jan 2026) · OCC annual volume (2019; 2025)

Winners and losers

Most people who trade options lose money.

87.7%

of individual derivatives traders in India lost money in 2025–26, after costs. Over 90% of the losses came from options.

US

In the US, retail options traders lose money on average, paying spreads of 12.6% on the cheap, short-dated options they favour.

The thesis

Great games make complex systems muscle memory. So we built one for options.

How it teaches

Every lesson starts as someone's real problem.

In the game

A captain wants to be sure she reaches shore. She pays you a due for safe passage. And scared captains pay double.

In the market

That's selling a put.

You're paid now for taking on someone else's risk. And when fear rises, so does the price of protection.

Mentorship

Trading is a blood sport. Nobody should face it alone.

Smudge was your father's cat. Smudge learns how you play, who you are and what you talk about, explains your mistakes, and never tells you what to buy or sell.

“You sold that one because you were frightened, not because anything changed. Shall we look?”

“And not every tide needs you. Sit with me a while.”

Smudge is designed and in development. Smudge's lines are drafts.

What it isn't

This isn't Duolingo. You learn through story, not drills.

Not Duolingo

No flashcards, no rote repetition. You keep playing to find out what happens.

Not a simulator

Play money with nothing at stake is easy to shrug off. Here, there's a town.

Not a tip service

We never tell you what to trade. We teach the judgement to decide.

Who it's for

Trading education has left most people out. Options can bring in a new kind of trader.

Left out by trading education

1 in 4 of India's investors is a woman. In the US, just 34% of women feel comfortable making investment decisions, against nearly half of men.

Coming in

28% of US millennial women investors have traded options or futures, against 10% of boomer women. 43% of US investors under 35 trade options.

Why options

Spot trading and perpetual futures reward one kind of trader. Options are another way to trade: protect what you own, earn income, fix your risk upfront. Many people who would suit it don't know it exists.

NSE Market Pulse FY26 · FINRA Foundation & GFLEC, 2020 · Charles Schwab Women Investors Survey 2025 · FINRA Foundation investor report, Dec 2025. “Why options” is our view, not a statistic.

Appetite, and where it is

Millions already learn through play. Tidewick is next.

I'm Koko. Help me build it.

An options trader, building the game I wish I'd had before my first trade.

Looking for: funding to finish chapter one, and people who have shipped story games.
