Test day is a bad place to meet the games.

Three different games

Red Rock is data and case math, Sea Wolf is constraint matching, Sustainable Futures Lab is prioritisation. Strong at one does not carry the others.

Minutes on a timer

Your invitation sets the length. Red Rock and Sea Wolf run on the clock, so read, decide and commit at that pace before test day.

Play each one here first. Scored, with every decision worked.

Original scenarios built to the stages candidates report. Every free run ends with your score. Use the arrows to step through each run.

Sustainable Futures Lab comes in two versions. Candidates report SFL Classic (13 decisions) with 85-minute invitations and SFL Island (a 30-minute, three-day team project) with 95-minute invitations. Each has its own practice below, and one SFL pack opens both.

A Red Rock run: the exhibit read for a hidden unit, three facts saved to the research journal, the answer worked on the calculator, then the review marked Correct.

The whole run on film: exhibit, journal, calculator, review.

Simulation 1 in full: the Study and six standalone Cases.

A Sea Wolf run: microbes screened against the site's ranges, a trio built and checked against each average, then the worked solution.

The whole run on film: screen, build the trio, check the averages.

Simulation 1 in full: all three sites. At each, set the profile, classify ten cultures, play four prospect-pool rounds and choose a three-culture treatment.

SFL Island on Day 1 Explore: a workstation panel open over the island with one question already used and its answer saved to Notes.

Explore: spend a few questions on what the day needs.

SFL Island

New 2026

The new 30-minute format reported on 95-minute invitations: lead four researchers across three days. Practice 1 is a full free project with a worked debrief, and 9 more come with the SFL pack.

A Sustainable Futures Lab run: five initiatives dragged into order against the ranking rules, the order confirmed, and the round marked Correct.

The whole run on film: rank, confirm, review.

Simulation 1 in full: 13 linked decisions on one project, from ordering the work to the scale call. The ranking-and-scenario format candidates report on 85-minute invitations.

Learn it untimed. Rehearse it on the clock.

Pictures show an earlier practice edition of the same Sea Wolf site in both modes, step by step. Learning explains every decision as you go. Simulation gives you the full clock and holds the explanation until the debrief.

Choose one attribute range and the Needed trait; your starting cultures stay the same.

Learning mode

Sea Wolf Learning mode, profile step: choose two preferences, no clock, with a Check profile button.
No clockCheck: feedback now
Check profile gives you feedback straight away.

Simulation mode

Sea Wolf Simulation mode, profile step: the same two preferences with a 9:00 clock and a Submit profile button.
Clock runsSubmit: feedback later
The same choice with the clock already running. Submit and move on.

Learning hints. Worked reasoning after every decision.

Start here, then switch to Simulation.

Simulation hints. None, and feedback held until the debrief.

Finish here, a few days before your test.

SFL Classic has no timer in either mode. SFL Island runs on a 30-minute clock in Simulation mode.

Know exactly where the points went.

Every run ends with a debrief that works the problem step by step, so the next run fixes something.

Earlier treatment-only Sea Wolf debrief after a Simulation run: 60 percent, nine of 15 treatment checks met, next steps, where the points went by site and each decision to review.

Earlier practice edition: Simulation score, next steps and points by site.

Your score, where the points went, and the next three runs.

  • Practice scoring: Profile 10%, Classification 20%, Pool viability 20%, Treatment 50%
  • Your points, and where you lost them by site or skill
  • Treatment ranges and trait checks, with the arithmetic shown
  • A read on hard filtering, boundary handling and treatment optimisation
