## Description

18 levels. Sweep every line off the board, alternating dots and bars. Each board is measured before you see it, so the difficulty fits. No ads, no purchases, offline.

Tentenbou ("dots and bars" in Japanese) is a one-stroke puzzle:
travel dotted lines and solid bars in alternation until every line
on the board is swept away.

■ Simple rules
- Travel lines in alternation: dots → bar → dots → ... (always start with dots)
- A line disappears once you have traveled it enough times; sweep them all to clear
- The ending matters: sweeping every line always lands you on the goal,
  so plan a route that reaches the goal last

■ Deep thinking
- Lines marked "x2" must be traveled twice — how you loop is the key
- Lines with an arrow are one-way. Take them from the wrong side too early
  and you can strand them
- Switch nodes flip the color (dots ⇔ bar) of every connected line
  when you land on them. The order of your steps changes the board!

■ 18 levels
- Clear a board without using any assist to earn a point. 3 points to advance
- Points are never taken away. Get stuck and take help, and what you have
  already earned still stands
- Finish every level for a COMPLETE!

■ Every board is measured, not just generated
- Each generated board is played out on the spot to measure how hard it
  really is, and only boards that fit the level are served
- Every board is guaranteed to have a solution

■ Features
- Four hand-crafted practice stages (loops, one-way lines, switches, triangles),
  all playable at any time straight from the home screen
- Stuck? Undo one move, rewind to a solvable point, or show a hint
- Illustrated "How to Play" guide
- No ads, no purchases, no data collection. Fully offline.
