low-floor
No stairs needed
Low-floor describes something designed with a minimal barrier to entry or participation.
A low-floor activity requires little prior knowledge or skill to begin.
The term comes from public transit—a low-floor bus lets passengers step on without climbing stairs.
In education and game design, the concept pairs with "high ceiling": easy to start, with room for mastery.
Chess has a relatively low floor but an extremely high ceiling.
