Sling (Yuki Games)
Five quick physics calls a day: say where the cannonball lands, the cut string flies or two dots collide, then watch.
Every day: Five physics prediction rounds (arc, spin, gears, bounce, meet) seeded by the date, identical for every player that day. New puzzle: Midnight in your own time zone (the menu counts down to local midnight).
Sling is a free browser game that tests your feel for motion. Each day brings five rounds, the same for everyone: predict where a cannonball lands, where a ball flies when its string is cut, which way the last gear turns, where a bounce ends up and where two moving dots meet. After each call the real motion plays out and you score 0 to 100.
About Sling (Yuki Games)
Sling is one of a set of small daily browser games by Yuki Andersen, alongside Gauge, Keel and Helm. It is about physical intuition rather than formulas: every round shows a bit of motion, asks you to commit to a prediction, then plays the true motion so you can see how close you were.
The daily gauntlet is seeded by the date, so every player gets the same launches, strings, gear chains, bounces and collisions. In Arc you see only the start of a cannon shot and tap where it will land. In Spin a ball whirls on a string that is cut at a marked point. Gears asks which way the last wheel in a chain turns, against the clock. Bounce shows a ball heading for a tilted pad, and Meet shows two dots gliding at steady speeds toward a collision.
Each round scores from 0 to 100 with partial credit for near misses, and your daily result is the average, shared as a row of five coloured squares. After finishing you see how many people played in the last 24 hours and the best score among them. A practice mode lets you drill any single skill up a 12-level difficulty ladder, and XP from every round climbs a rank ladder kept in your browser.
The whole daily takes about a minute, needs no account and runs on phones and school Chromebooks, so it suits anyone curious about how good their eye for motion is.
How to play Sling (Yuki Games)
- Open Sling and start today's gauntlet.
- Watch the short preview of motion in the round.
- Tap where you think the ball, string or dots will end up (or pick the gear direction).
- Press LOCK IN to commit your call and watch the real motion play out.
- Finish all five rounds and share your average score.
Tips
- Arc: steep launches climb more and land shorter than they look.
- Spin: a cut string sends the ball in a straight line along the direction it was moving at the cut.
- Gears: count the meshes; an odd number reverses the direction, an even number keeps it.
Questions
Is the daily the same for everyone?
Yes. The five rounds are seeded by the date, so all players get identical launches and gear chains.
How is it scored?
Each round scores 0 to 100 with partial credit for close calls; your daily score is the average of the five.
Do I need an account?
No. It is free, runs in the browser and keeps your stats on your device.
Can I practise?
Yes. Practice mode offers endless rounds of any single skill with a 12-level difficulty ladder.
