One complete free run of each practice game: Red Rock, Sea Wolf, SFL Classic and SFL Island, with your score and worked review. Start without an account; a free account is needed to finish and keep the debrief.
Original scenarios built to the stages candidates report. Each format includes one complete free run, your score and worked feedback with visuals. Start without an account; a free account is needed to finish and keep the debrief. 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.
Investigation: save the facts the answer needs to your journal.
Analysis: pick the chart that shows what the board asks for.
Cases: choose the evidence, then calculate.
Debrief: your score by phase and the step that cost the most.
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.

Simulation 1 in full: one ranking and twelve situational decisions on one project, with no countdown. The ranking-and-scenario format candidates report on 85-minute invitations.
Pictures show an earlier practice edition of the same Sea Wolf site in both modes, step by step. Learning provides coaching and feedback as you go in all four practice games, untimed in the clocked games. It requires the matching game pack, the Solve pack or qualifying Annual access. The free Simulation run includes its worked review at the end.

Know exactly where the points went.
Your completed free run includes your score, where points went and worked feedback on each submitted decision. Visual explanations include highlighted calculations and charts in Red Rock, constraint and treatment visuals in Sea Wolf, decision and dependency diagrams in Classic, and evidence chains, placement maps and team feedback in Island. No payment is required for that first worked review.
