No.258Paper Trail01The core loop
Action → feedback → next choice- 01Look at both sides
- 02Choose a fold
- 03Check the new path
- 04Unfold or fold again
↻Feedback changes the situation — the next round starts from there.
Walk through one round
A simplified design example. Situations and numbers illustrate the mechanic, not exact rules from a reference game.
- T1
Turn 1 · The situation
The hero is bottom-left, the exit top-right, a river between.
- T2
Turn 2 · The player chooses
Fold the top-right corner down so the bridge on the back covers the river.
- T3
Turn 3 · The feedback
The bridge connects, but the exit is now folded out of sight.
- T4
Turn 4 · The next decision
Cross, unfold, then fold from the other side.
How it plays
The world is drawn on paper that folds along edges, laying the back over the front. A fold may join paths or hide them. Players imagine both sides and the order of folds.
What the player weighs
- Fold to open a path or keep the old one exposed
- Fold a big panel or a small corner first
02Start small

03One mechanic, different implementations
Paper Trail
Players fold a world drawn on paper, the back overlaying the front, to join paths and avoid obstacles for the heroine.
Tengami
Themed as a Japanese pop-up book, players pull and fold paper structures on the pages to change scenes and open routes.
The difference worth noticing
Paper Trail's folding follows systematic grid rules; Tengami's is more about pop-up book scene transformations.
Case notes are Yoroll editorial summaries; rules may change between versions.
04What could you combine?
The backpack is a foldable map: folding stacks cells to fit bigger items but hides route information on that part of the map.
