How to play

OneStroke starting
This is an example of a OneStroke starting grid. The aim of a OneStroke puzzle is to draw all of the lines in this puzzle without lifting your finger (or mouse) off the puzzle, i.e. in one stroke.
It is possible to lift your finger/mouse off the puzzle to have a think about your next move, but you will need to continue from your last point.
Some lines will have arrows on them, and they have to be drawn in that direction. Some lines will be dotted, and they will need to be traced twice.
OnStroke partial solution
You can see here that we have started this puzzle. We have drawn over the dotted line once, and you can see that line has changed colour.
If you decide you have made a mistake, you can retrace your path back to the previous point as many times as you want. Alternatively, you can always reset the puzzle.
