Decision matrix
When to use it
When comparing options against several criteria.
How to use it
Filter hard constraints, define criterion direction and weights, compare, then vary weights to test stability.
A real-life example
A purchase budget cap is a hard constraint. Efficiency and energy use can be weighted; weights express preferences, not objective truth.
Try it in a game
Six two-piece handovers: new goals on the same board, upfront costs, hard constraints and your own weights. Compare full consequences, then test other priorities in review.
Play Before the Drop: Classic Line ClearingAfter playing, ask yourself
Which move changed your later choices? If conditions changed, would the same approach still work? What evidence would you need to check before applying the relationships in this game to real life?
Games are simplified practice environments for exploring tools and when to use them. Completing a game does not demonstrate mastery and is not a personality or professional assessment.
