Ranks and difficulty, game by game
Every title runs its own promotion ladder, and no two use the same number of rungs or the same names.
The general shape of rank progression — solve cases, get promoted, unlock harder assignments — holds across the series, but the actual ladders are specific to each game and worth listing on their own, since fans moving between titles tend to assume one game's ranks apply to all of them.
The ladders
- Where in the World (1985): five ranks, Rookie up to Ace Detective.
- Deluxe (1990): nine ranks, from Gumshoe to Super Sleuth — the manual's own wording is “you start as a Gumshoe, and move up through eight ranks finally reaching Super Sleuth,” i.e. eight promotions on top of the starting rank — with Hall of Fame induction waiting at the top and retirement offered after roughly eighty cases beyond that.
- Where in the U.S.A. (1986): ten ranks culminating in Super Sleuth status, plus further Special Commendations beyond it; promotion between ranks is gated by a short quiz rather than case count alone.
- Where in Time (1989): seven ranks — Time Cadet, Time Patroller, Time Investigator, Time Inspector, Time Detective, Ace Time Detective, and Super Time Sleuth — with retirement offered after about eighty cases.
- America's Past (1991): eight ranks, from Greenhorn and Tenderfoot through Jr. Birddogger, Birddogger, Jr. Tracker, Tracker, Scout, and SuperScout, with the same pattern as Deluxe: Hall of Fame induction at the top rank, retirement offered after roughly eighty cases beyond it.
- Where in Space (1993): seven ranks, Space Cadet up to Sun Admiral, also ending in Hall of Fame induction.
- Where in Europe (1988): eleven ranks, from Gumshoe up to Super Sleuth — the same top rank as Deluxe and the U.S.A. game, reused for a third title.
- Junior Detective (1995): no ranks at all — fourteen flat cases with no promotion structure, in keeping with its much younger audience.
What actually gets harder
Across the games that do rank a player, the same few levers get pulled while climbing: cases arrive with less time on the clock, pull from a larger suspect pool, and eventually name Carmen herself rather than one of her gang. The 1985 manual states the principle outright — “the higher you rank, the tougher the case” — and every later title inherits some version of it, even where the specific dial being turned isn't spelled out in the surviving documentation.
