A little perspective.
Every day.

How tall? How far? How many? Plain Game turns the scale of the world into a short daily flight.

You do not need perfect recall. Read a target, name something close, and see how your intuition compares with a sourced number. Each good answer carries your plane higher.

A game you can come back to

Everyone shares seven daily questions. Between flights, explore 27 topics across 15 areas, practise four question types, choose a difficulty or try Survival. Daily missions, levels and lasting badges record what you learn.

Better with a crew

A challenge link lets a friend try your flight. Groups put your daily and weekly climbs together without requiring everyone to create an account. Your guest passport is saved on the server and this browser; an optional configured account adds cross-device sign-in.

Numbers with a source

Each topic has a defined scope and a fixed data snapshot. Sources appear alongside the answers and on our Sources page. Snapshot values can differ from a current live statistic; the named snapshot is the value used for every player.

Independent by design

Plain Game is an independent game inspired by Plain. We are not affiliated with its creators. Our implementation, illustrations, extra practice modes and progression are our own.
