Player observation, behavior acceptance and finding accessibility barriers.

## Before you start

- [Scope and a testable prototype](https://gamemechanics.pro/en/lessons/scope-and-prototype/)
- [States and transitions](https://gamemechanics.pro/en/lessons/state-machines/)

## Lesson sequence

1. [Running a playtest with a concrete question](https://gamemechanics.pro/en/lessons/running-a-playtest/)
2. [Verifying gameplay behavior](https://gamemechanics.pro/en/lessons/gameplay-acceptance/)
3. [Basic accessibility across a play session](https://gamemechanics.pro/en/lessons/game-accessibility/)

## Put it into practice

Use the exercises to check decisions from the lessons. Preserve conditions and comparison results.

- [Three minutes at the museum](https://gamemechanics.pro/en/practice/#three-minute-museum)
- [Rhythm without rushing](https://gamemechanics.pro/en/practice/#rhythm-without-hurry)

## Outcome

A repeatable acceptance scenario, playtest record and list of accessibility barriers.

## Completion checks

- Expected behavior is distinct from observations.
- Checks run in the target environment with recorded conditions.
