Ease Match
A ball moves once with a hidden easing curve; pick the curve that matches.
How to play ↓A ball travels from A to B once. Then four curve cards appear, each a plot of how far the ball has gone against time. Pick the curve that matches how it moved. Press Start to watch the first ball.
Assist mode: you can watch the ball again, at normal or half speed, up to 2 times per round. Looking again caps that round at 8 points.
How to play
Five rounds. In each one a ball travels from A to B in about a second, once. Then four curve cards appear. Each card is a plot with time running left to right and distance travelled going up. Pick the curve that matches how the ball moved: a straight line is a steady speed, a curve that starts flat is a slow start, and one that levels off at the top is a slow finish.
The first two rounds use clearly different curves. Later rounds add stronger and subtler versions, overshoot, pulling back, steps, bounce and spring, and the wrong choices are the curves closest to the real one. A right pick scores 10. A wrong pick can still earn up to 6, depending on how close its curve is to the real one. The total is out of 50.

Ways to play
- Click, tap, or use the keyboard as above.
- Assist mode: watch the ball again, at normal speed or half speed, up to twice per round. Looking again caps that round at 8 points.
- Progress bar: a bar fills in the same way instead of a ball moving. It is still motion, only simpler.
- Reduced motion: the movement is the thing being judged, so it stays, but it is shorter and nothing else bounces or sparkles.
Who this works for
Sighted players who can judge motion. You have to watch the ball to know how it moved, so there is no non-visual version. Each card has a plain-words description for screen reader users, such as "starts slow and ends fast", and after every round the result is written out, but the ball itself cannot be described without giving the answer away. This has not yet been checked with a screen reader.
