Pick a unit. Set prices, choose strategies and work the cost curves.
Not tied to a unit — all six units of AP Micro in one multiple-choice game with a graph you can move.
Every multiple-choice question comes with a graph.
Practices Supply and demand shifts, elasticity, price controls and taxes, trade, cost curves, monopoly, game theory, factor markets and externalities.
Drag a curve or a slider, watch the equilibrium change, then pick your answer. Claim lands on a map, take the Exam Hall at 70 seconds a question, and play a new daily graph each day.
Scarcity and gains from trade — absolute advantage, opportunity cost, and terms of trade.
Ten rounds. Place one die each round: take the sure points, park it in Long Term to multiply later, or burn the round on Spite.
Practices Opportunity cost, sunk cost and marginal cost.
Parking a die gives up that round's points.
Five rounds.
Practices Absolute advantage, opportunity cost, comparative advantage and terms of trade.
Work out the advantages from plant data, then decide whether the proposed terms are worth signing.
Which events move the curve, which put the economy inside it, and which slide it along.
Practices The production possibilities curve: shifts, idle resources, opportunity cost and economic growth.
Play solo missions, duel a rival who sets traps, or pass one device between a Saboteur who picks the event and an Analyst who calls it.
Elasticity applied to real pricing calls, plus price ceilings and floors — why the same price hike saves one firm and sinks another.
Five rounds. Pick the right formula, compute the coefficient, then recommend HIGH, MARKET or LOW pricing.
Practices Elasticity: PED, XED, YED and PES.
Every call swings company revenue.
Twelve levels. Drag a legal price line across a supply and demand graph and watch the queue or the pile appear.
Practices Price ceilings and price floors: binding and non-binding prices, shortage and surplus, consumer and producer surplus, deadweight loss and the role of elasticity.
Later levels read the surplus areas, predict a shift in supply, and turn the feedback off until you submit.
Six dials on one supply and demand market.
Practices Supply and demand: equilibrium price and quantity, consumer surplus and producer surplus.
Some events leave price or quantity indeterminate, so a Slyder, the table's hidden saboteur, can peg either dial and defend it.
Read the graphs, finish the cost table, and decide how much to make — or whether to shut down.
Four quarters, about ten minutes.
Practices Perfect competition: marginal cost, MC = P and profit maximization.
You own a small business with $500. Read the graph, finish the cost table, find MC = P, and set output.
Call what happens right after a shock, then what entry and exit do in the long run.
Practices Perfect competition: the market and the firm side by side, short-run profit, entry and exit and zero economic profit.
Play solo missions, duel a rival who sets traps, or pass one device between a Saboteur who picks the event and an Analyst who calls it.
Payoff matrices, dominant strategies, Nash equilibrium, and why collusion falls apart.
Five rounds, 11 scenarios.
Practices Game theory: dominant strategies, Nash equilibrium, prisoner's dilemmas and coordination games.
Find both firms' dominant strategies, click the Nash equilibrium on the payoff matrix, then make the call.
Move demand, marginal cost and fixed cost, and see which calls change and which do not.
Practices Monopoly: MR = MC, price, profit, deadweight loss and price regulation.
Play solo missions, duel a rival who sets traps, or pass one device between a Saboteur who picks the event and an Analyst who calls it.
MRP, labor supply, the wage, and what a minimum wage does when there is one employer.
See what a wage floor does in a competitive market, then in a monopsony.
Practices Factor markets: MRP, labor supply, the wage, minimum wage and monopsony.
Play solo missions, duel a rival who sets traps, or pass one device between a Saboteur who picks the event and an Analyst who calls it.
Externalities, the gap between private and social value, and what a tax, subsidy, rule or deal does to it.
Read the graph before the event hits, then call every change.
Practices Externalities: the four CED graphs, the socially optimal quantity, deadweight loss, and what a tax, subsidy or deal does to the gap.
Play solo missions, duel a rival who sets traps, or pass one device between a Saboteur who picks the event and an Analyst who calls it.
Six dials on one market with a positive or negative externality.
Practices Externalities: marginal social cost and benefit, the socially optimal quantity, deadweight loss and taxes and subsidies.
A tax cuts output and a subsidy raises it, so a Slyder can defend the wrong sign.
