What it is

Trail Drag is the catalogue's gentlest game — and its quietest test of motor control. A curved line is drawn on the canvas, with a green start dot and an orange end dot. You press down at the start, drag along the line, and lift at the end. Your score is the average perpendicular distance between your trace and the actual curve, inverted and scaled — closer to the line = higher score. Perfect would be 100; a casual run typically lands between 60 and 80.

How to play

Press at the green dot. Start the trace.
Drag along the line. The line is white; the trail you leave is orange.
Don't lift until the end. Lifting mid-curve ends the run early with whatever score you've earned so far, plus a penalty.
End at the orange dot. Your run is scored and saved as best (if higher than your previous).
Each new run draws a new random curve — two control points, smooth Bezier-shaped.

The trick

Speed and accuracy are in tension. Most beginners try to be slow and careful and end up trembling, which is worse than moving steadily. The trick is to move at constant moderate speed, looking slightly ahead of your finger rather than at it — the same principle that makes you drive better when you look down the road rather than at the hood. The eye corrects the hand based on prediction, and prediction needs space to act.

What this scored well on

Generous scoring. Distance from the line is converted into a score with a gentle curve — small errors don't punish much, large errors punish a lot. Most players feel "I did well-ish" rather than "I failed", which is the right emotional register for a precision game.
Pointer events. The game uses pointer events, so mouse, touch, and pen all behave identically. A tablet with a stylus is a fun way to play, but not required.
Honest curves. The procedural curves are generated to be tricky-but-fair — no sudden reversals, no microscopic detail, just one or two natural-feeling bends.

What it gets wrong

Trail Drag rewards device quality in a way the other games don't. A laggy old phone makes the curve harder to follow. A high-refresh-rate stylus on a recent iPad makes it easier. We minimised this by sampling the trace at 60Hz regardless of device, but the underlying motor task is the same and faster hardware really does help. If you find this game punishing on your device, that's likely the reason.

Who it's for

Trail Drag is for the kind of player who appreciates a game that's quiet and analytic rather than loud and reactive. It's also a useful warm-up for any fine-motor task — handwriting, drawing, surgery (if applicable). Five minutes of Trail Drag visibly steadies the hand for half an hour.
