The level was fair.
You weren't ready.

Phoebe is an infinite, deterministic, progressively harder minimalist game. Every level is provably fair; every failure gives a specific reason. It runs entirely on your device — no account, no sign-up, no personal details.

Provably fair

No rigged levels. No fake difficulty. Just you, losing.

01

Seeded

Every level is generated from a number. The same level is the same for everyone, forever.

02

Validated

The engine solves each level before you see it. If it isn't beatable, it's re-rolled.

03

Explained

Miss, and you get the exact reason — off by 14%, 0.2s too late, wrong tile.

Eight ways to lose

Eight challenge families, each with a thousand-plus hand-tuned difficulty steps. Then Level Devil starts changing the rules while you play.

Precision

Land the dot. It looks right. It isn't.

Timing

One tap. One window. No second chance.

Balance

Hold the beam steady while it fights you.

Trace

Follow the corridor without touching a wall.

Sequence

Watch the order. Repeat the order.

Stack

Drop the block. Build the tower higher.

Observation

Find the one that doesn't belong.

Level Devil

The rules change mid-play. On purpose.

Private by default

Progress lives on your device. The optional leaderboard uses an anonymous ID and a random handle — never your name or email.

Ads only when you ask

One rewarded ad, watched by choice, buys a single extra life. Decline tracking and they become non-personalised.

You're in control

Opt out of the leaderboard, ads, and notifications anytime — and request full deletion of anything stored.

Every failure has a reason. It's just never a good enough one.
