Daily one-button pendulum puzzle
ArcSwing
Swing a pendulum through target gates by holding to extend and releasing to retract the rope. A one-button physics puzzle with daily seeded layouts.
Statistics
Frequently Asked Questions
How does ArcSwing work?
A ball hangs from a pivot and swings like a pendulum. Hold to extend the rope (wider, slower swing) and release to retract it (tighter, faster swing). Swing through all the target gates to win.
What do the difficulty levels change?
Easy has 8 gates with reduced gravity. Medium has 10 gates at normal gravity. Hard has 12 gates with increased gravity — tighter timing and more targets to hit.
Is the daily puzzle the same for everyone?
Yes. The daily gate layout, rope length, and gravity are generated from the UTC date, so every player worldwide gets the same puzzle each day.
How is the grade calculated?
Your grade depends on how many swings you used compared to the optimal number. S grade means you matched or beat the optimal count. A is within 1.5x, B within 2x, and C is above 2x.
What Is ArcSwing?
ArcSwing is a daily one-button pendulum physics puzzle. A ball swings from a rope and you control its arc by holding to extend or releasing to retract. Clear all target gates in the fewest swings possible.
How to Play ArcSwing
Hold anywhere on screen (or press Space) to extend the rope — the ball swings wider and slower. Release to retract — the ball snaps tighter and faster. Time your holds to thread the ball through every gate.
Why Pendulum Physics Games Train Spatial Intuition
Predicting a pendulum's arc requires reading continuous motion and timing your input to the phase of the swing. This spatial-temporal reasoning is a distinct cognitive skill from reaction-based or logic-based games.
