Puzzles & Survival, with the numbers actually written down

Tools and answers for a game whose community has been guessing. Every figure here is traceable to a source we kept — and where we do not know, we say so.

Ultimate Challenge answers

71 levels with verified solve footage. The only index of its kind anywhere.

Immigration ticket planner

26 HQ levels. How many flight tickets you need to change state — a question nothing in English answered.

HQ upgrade costs

54 verified figures, cross-checked across two sources, published as approximate.

How we verify

What we keep, what we refuse, and why a gap beats a guess.
