Question 1

What are market making games?

Accepted Answer

Market making games are skill-based browser simulators built around the core tasks of a proprietary trader: quoting a two-way price, managing inventory and spread, and taking the other side when edge appears. They are designed to develop the same fast, probabilistic decision making that firms like Optiver, IMC, Flow Traders, SIG and Jane Street screen for during their interviews and trials.

Question 2

Are these games free to play?

Accepted Answer

The easy difficulty of every game is always free and will stay that way forever, with no login required. A free account saves your scores and history; Tradermath Premium unlocks the Medium, Hard and Custom difficulties.

Question 3

How do difficulty levels and scoring work?

Accepted Answer

Each game ships with easy, medium and hard difficulties. Stepping up the difficulty shortens the time per decision, adds more rounds, enables market events, and hides helper information like your balance. Your best P&L per game and per difficulty is stored on the market games dashboard so you can track improvement over time.

Question 4

Will these games help with quant trading interviews?

Accepted Answer

Yes. The Trading Game and Market Making Dice Game drill the exact quoting and inventory questions that show up in Optiver and Flow Traders assessments. ETF Arbitrage mirrors the mispricing identification questions that are common at IMC and Jane Street. The Card Game reflects expected value questions asked by SIG. Fermi Estimation is a direct echo of the brainteasers used by almost every proprietary trading firm.

Question 5

Which skills does each game train?

Accepted Answer

Trading Game and Market Making Dice Game build spread discipline, inventory awareness and two-way pricing. ETF Arbitrage builds cross-asset pricing and reaction speed against competing traders. Card Game builds expected value intuition and edge detection. Fermi Estimation builds calibration of confidence intervals and Bayesian updating under uncertainty.

Question 6

Do I need a finance background to play?

Accepted Answer

Not at all. The easy difficulty of each game teaches the core concept step by step, which makes the games well suited to students, career switchers and early-career traders. What matters most is comfort with quick mental math and probability, both of which the games themselves help you develop.
