Across
- 2. (or constant-sum) game: one player's winnings are the others' losses, so the net gain is zero across all players
- 3. player must try to reason what his opponent will do now, knowing that she will be asking the same question herself, and so on.
- 9. game: when agreements are not enforceable (although players may still have common goals, such as the Battle of the Sexes)
- 12. behaviour: players are perfect calculators and flawless followers of their best strategies
- 13. payoffs must be cardinal, not ordinal, in this case.
- 15. simply the choices available to the players
- 16. all that is important to a player about the game. For example: profits, market share, envy of rivals' positions, etc.
- 17. a once-off simultaneous game, simply the action taken on that single occasion. With sequential moves, a strategy could be "If he chooses X, then I'll choose B, but if he chooses Y, then I'll choose A" -- a complete plan of action.
- 18. an interaction between (or among) mutually aware players
Down
- 1. game: when joint-action agreements, pre-game contracts, etc. are enforceable
- 4. moves: players move together, in ignorance of the others' moves
- 5. (or non-zero-sum or variable-sum) game: players have some common interests; not constant-sum, which means that win-win or lose-lose is possible in two-person games
- 6. player must think: If I do this, how will my opponents react?
- 7. moves: players do not move together
- 8. the number (ordinal or cardinal) attached to an outcome
- 10. the consequence for a player of a specific combination of all players' strategies
- 11. payoff: the weighted average of all possible outcomes, where each weight is the probability of that outcome's occurring
- 14. each player is using the strategy that is his best response to the strategies chosen by the other players
