Overview
The Basketball Market Making Game combines live sports dynamics with real-time trading. Two teams, the Lions and the Tigers, play a simulated four-quarter game while markets open on outcomes like the game total, quarter and half totals, each team score, the final margin and the biggest lead. Behind the scoreboard runs a full engine: team strength drives ball possession, heavy possession drains fitness faster, and lower fitness cuts shooting accuracy, so the numbers you trade on are always moving. Your job is to read that information flow, price each market, buy when you think the outcome will finish higher and sell when you think it will finish lower, and manage a book of positions across several markets at once for the best final profit.
Example: one market during Q3
A simulated match runs quarter by quarter while markets open and close around it: quarter totals, final totals, the score difference, the biggest lead. You get each team’s strength, shooting precision and fitness, so you can price the rest of the game better than the quoted market does.
Markets close on a countdown, so the read has to be quick. Positions stay open until the outcome they cover is settled.
Game Phases
1
Watch the simulation Follow the live game: the clock, both scores, possession share and each team fitness. Teams average about five points a minute, and tired teams shoot worse, so momentum and fatigue keep moving every market.
2
Read the markets Markets open throughout the game on totals, team scores, the final margin and the biggest lead. Each one quotes a price for a future outcome and stays open for roughly two game minutes before a new one appears.
3
Take a position Buy if you think the outcome will finish higher than the quoted price, sell if you think it will finish lower. Every trade is for one unit, and you can hold positions across many markets at the same time.
4
Manage risk and settle Diversify, hedge correlated markets and size your exposure. Positions settle at the true outcome, and your combined profit and loss across all markets is your score.
