Draw the hidden symbol for the word.
The dots are where its lines meet. The number on a dot says how many of its lines touch it.
Tap one dot, then another, to guess a line between them. A right guess draws the line, and the pen waits at its end for your next tap. A wrong guess leaves a dotted mark and costs a try. Tap the pen's dot to lift it and start somewhere else.
Find every line. Par is no wrong guesses. Early boards can be solved from the numbers alone; later ones need the word, and your misses, to help.
Tap a dot, then another — guesses the line between them
Drag — guesses each dot you pass
← ↑ → ↓ then Enter — chooses a dot; Z undoes, H hints
The numbers work as in Hashiwokakero, the bridges puzzle. Charles Bliss built his symbols (Semantography, 1949) from a few shapes drawn on a square between a skyline and an earthline, so a hand that knows the meaning can find the shape. Moving a pen from point to point is EdgeWrite's idea (Wobbrock, Myers and Kembel, 2003), made with the eyes in EyeWrite (2008).
