Lost Marbles · How to play
Lost Marbles is a room-based puzzle game with marbles, doors, crates and hazards. A move can affect several interacting objects, so planning the order of moves matters as much as reaching a visible exit.
Controls
Press Enter/Space to start, then use arrows or WASD to move. R restarts the room; touch direction and Start buttons are included.
Rules & goal
- Start from the title and move through the first room with directional inputs.
- Use the room’s switches, levers and movable objects to change blocked routes.
- Avoid traps and guide the pieces toward the exit; restart the room when necessary.
Beginner tips
- Notice which objects move together after one directional input.
- A safe setup move can be more useful than immediately moving toward the door.
- The game moves on key release; touch buttons apply one move when you lift your finger.
