TradeQuest

Rock, paper, scissors, except you have to buy your hand first.

Nine cards trade on a live market for five minutes. News moves prices every 10 seconds. Buy cheap, sell high, and make sure you're holding the right cards when the market closes, because then you duel the bot with them.

Half your score is how well you traded. The other half is how well you fought.

• Three difficulties

• Global leaderboard

• Send a friend the exact same market and compare scores

Built by two first-year students at IIM Kozhikode. Gameplay is recorded anonymously for a research project on how people trade.
