  3. 03Rate how fair the exchange was, from 0 (very unfair) to 10 (very fair).
  4. 04The partners are simulated by Candidate Falcon and follow return rules we designed. You meet three of them.
  5. 05There is no right amount. Choose the way you naturally would.

What the pymetrics Money Exchange 1 game looks at

Money Exchange 1 is pymetrics’ version of the trust game, a classic task from behavioural economics. pymetrics’ patent describes it: you send money to a partner you do not know, the amount is tripled on the way, and the partner decides how much to send back. Prep sites describe the screen as $10 for you and $0 for your partner, with a choice of $0 to $10 in $1 steps, followed by a question about how fair the exchange was.

pymetrics says its games have no right or wrong answers, and Harver lists fairness, generosity and risk tolerance among the trait areas its games cover. In research, the amount sent is usually read as trust and willingness to take a risk on someone else, and the rating shows how you judge the outcome. pymetrics compares how you play with people who do well in the role, so there is no target amount to aim for.

Candidate Falcon’s practice gets you used to the format. The partners are simulated, and what they send back follows rules we designed, because pymetrics does not publish how its partner behaves. You play three rounds with three different partners, rather than the single round prep sites report, so you can see how you react when different amounts come back.

How the Money Exchange 1 practice works

  1. Press Start practice. You hold $10 and your first simulated partner holds $0.
  2. Choose how much to send with the slider, the − and + buttons or the arrow keys, from $0 to $10, then press Send.
  3. The amount is tripled for your partner, who sends some of it back. You see what both of you now have.
  4. Rate how fair the exchange was, from 0 (very unfair) to 10 (very fair), then meet the next partner.
  5. After three partners, review what you sent, what came back and your ratings. The partners’ rules are revealed at the end.

Money Exchange 1 tips

  • There is no right amount. Decide the way you would with real money and someone you have never met.
  • Read the numbers before you rate: what you sent, what your partner received after tripling, and what came back.
  • Pick the rating that matches how the exchange felt to you. The whole scale is there to use, ends included.
  • Our practice is untimed, so take a moment before you press Send. The slider starts at $0 and does not suggest an amount.
  • Expect one decision in the real game: prep sites report a single exchange, so treat each practice round as a fresh start.

Common Money Exchange 1 mistakes

  • Looking for a correct amount to send. pymetrics says there is none.
  • Rating the exchange before checking how much your partner received after tripling.
  • Assuming the partner is another candidate. Prep sites describe it as an algorithm.
  • Changing your natural choice because a forum suggested a strategy.

A short Money Exchange 1 practice routine

  1. Play one run, then read the review: what you sent to each partner and how you rated each return.
  2. Notice whether your ratings followed the money that came back, or something else such as whether you got your own money back.
  3. Play Money Exchange 2 next. It uses the same fairness question in a sharing game.
  4. Before the real assessment, play once more so the screen feels familiar, then answer naturally.
