01 · Look
The room never changes shape.
What changes is what you have to realise. A wall that lies about its own number. A door that will not take a single finger seriously.
Lateral-thinking puzzles
The first door opens when you walk into it. The second one does not, and from there the room stops playing fair. The answer is almost never in the room. It is usually in your hand.
The door is on the right.

Thirty single ideas
01 · Look
What changes is what you have to realise. A wall that lies about its own number. A door that will not take a single finger seriously.
02 · Reach
Some trials are solved by tilting, shaking, charging, muting, or laying the iPhone face down. Roomerang never changes a setting for you. It just notices.
03 · Unlearn
A third of the trials subvert something the earlier ones deliberately taught you. Every door fills as you get closer, so you always know whether what you just did counted.
Private by design
Roomerang has no accounts, network requests, advertising, analytics, tracking, purchases, or third-party SDKs. Every hint, answer, and skip is free.
