## How it works

Observation, experimentation, and returning to known locations reveal hidden areas and rewards.

## Variants

### Variants and applications

<a id="family-group-18-variants"></a>

- Hidden passages. Rule: Geometry or camouflage hides the route from normal inspection. <a id="variant-mv-199"></a>
- Non-destructive revelation of illusion. Rule: Approaching, touching or special mode reveals a false wall. <a id="variant-mv-200"></a>
- Visual and audio cues. Rule: An unusual detail signals a possible secret or rule in effect. <a id="variant-mv-201"></a>
- An inaccessible reward in plain sight. Rule: The player sees the goal in advance and later returns with a suitable means... <a id="variant-mv-202"></a>
- Branch reward. Rule: An optional path gives an item, knowledge, resource or a new route. <a id="variant-mv-203"></a>
- A chain of interconnected secrets. Rule: One find tells you where and how to look for the next one. <a id="variant-mv-204"></a>
- Multi-stage mystery. Rule: The solution requires collecting information from several areas and systems. <a id="variant-mv-205"></a>
- Challenge for improvement. Rule: The permanent reward is hidden behind a separate movement, combat or observation task. <a id="variant-mv-206"></a>
- Knowledge of new uses for old tools. Rule: Understanding expands the capabilities of an existing set of actions. <a id="variant-mv-207"></a>
- Reward for returning after the event. Rule: The state of a familiar place changes and reveals a new research result. <a id="variant-mv-208"></a>

## Context and limits

The author's working taxonomy of mechanics, access rules, structural patterns and support systems. This is not an industry standard or a statement that every item is required or present in every game. Hybrids and support are highlighted separately. Any finite list is limited by the level of detail; combinations and new options remain open.
