How Pixactly scoring works.
Pixactly scores visual precision by comparing the rectangle you draw with the target dimensions shown for the round. The score is meant to be plain. If your rectangle is close, you did well. If it is off, the game shows where the miss happened.
Width error and height error
Each round has two separate measurements. Width error is the difference between the target width and the width you drew. Height error is the difference between the target height and the height you drew. If the target is 180px wide and you draw 194px, the width error is 14px. If the target is 120px tall and you draw 111px, the height error is 9px.
The split matters. A single total can hide what actually happened. Two players can both miss by 25px overall, but one may be stretching every rectangle while the other keeps drawing short. Those are different problems, so they need different practice.
Total off
The round score is based on total pixel error: width error plus height error. Lower is better. This keeps the game direct and avoids complicated scoring that would distract from the main skill. You are not trying to create a beautiful shape. You are trying to match the dimensions as closely as possible.
A 0px round is possible, but it is rare enough that it should feel a little accidental. Most useful sets are not perfect. They are the ones where you can say, "I keep going 12px too wide," and then make a better attempt next time.
Accuracy percentage
The accuracy display helps translate raw pixel error into a more intuitive result. A 10px miss on a very large target is not the same experience as a 10px miss on a tiny target. Looking at both the pixel error and the percentage gives a clearer read on the quality of the attempt.
If you only look at percentage, you may miss the practical detail. If you only look at pixels, tiny targets can feel harsher than they are. The two numbers together are more honest.
Time is there, but it is not the main point
Pixactly shows the time for each round because hesitation is part of the feel of the game. Still, speed is not the first thing to chase. A fast bad guess does not teach much. A slower guess with a clear miss is more useful while you are learning your own bias.
Once your misses get smaller, then speed becomes interesting. At that point you are testing whether your first read is calibrated enough to trust.
Final score and personal best
Pixactly uses a five-round set. At the end, the final result shows your total performance and round-by-round details. The browser also stores your personal best locally on the same device. That local record is useful for practice because it gives you a baseline without requiring an account or leaderboard.
Treat the score as feedback rather than judgment. A higher score tells you where your eye drifted. A lower score means your estimates are getting tighter. The most useful result is the one that tells you what to try on the next set.
For practice, compare sets on the same device. A laptop, phone, and big desktop monitor all change the physical feel of a pixel. That is part of the challenge, but it also means your best score is most meaningful when the screen stays the same.
