About this game

MONOLINE - ONE LINE DRAW PUZZLE

One shape. One stroke. Don't lift your finger.

Trace every line of the shape without lifting your finger from the screen
and without going over any line twice. Simple to understand, genuinely
hard to master.

HOW TO PLAY

Put your finger on a dot and drag. Every line must be drawn exactly once.
Lift your finger before the shape is finished and the attempt is lost, so
think before you commit. Made a wrong turn? Slide back along the line you
just drew to rub it out - no buttons, no menus, your finger never leaves
the glass.

The trick is that most shapes can only be finished from one or two starting
dots. Finding where to begin is often the whole puzzle.

EVERY LEVEL IS PROVEN SOLVABLE

Every one of the 38 levels is checked by the game's own solver before it
ships. No impossible boards, no guesswork, no dead ends that were never
meant to be there. If a level is in the game, it can be drawn in one
stroke - and the puzzle is finding out how.

NO TWO LEVELS ASK THE SAME QUESTION

Most one line games hand you the same puzzle forty times with a different
picture on top. Monoline is built to avoid exactly that. Each level is
measured against the ones around it, and shapes that pose a question you
have already answered do not make the cut.

WHAT YOU GET

- 38 hand-checked levels across 5 chapters
- A difficulty curve that rises deliberately, level by level
- Three stars per level: solve it, solve it without a hint, then solve it
flawlessly on your first try
- Your best run is always kept, so replaying a level can never cost you a
star you already earned
- A hint when you are truly stuck - it costs a star, never your progress
- Clean, minimalist design with no clutter and no timers
- No forced tutorials - the first levels teach by being played

FOR PUZZLE FANS

If you like brain teasers, logic puzzles, connect the dots, maze and path
drawing games, or anything that rewards thinking before acting, Monoline
will suit you. There is no time pressure and nothing to rush. Take as long
as you like.

A NOTE ON THE MATHS

One stroke puzzles are older than they look. The rule behind them was
worked out by Leonhard Euler in 1736: a shape can be drawn in one unbroken
line only if it has exactly zero or two dots with an odd number of lines
meeting at them. Monoline is built on that theorem rather than on trial and
error - which is why every level is guaranteed to have a solution.
