## What is Tentenbou?

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.

## Version history (last 4 releases)

### 1.4.0 — 2026-09-27

- A fresh look for the board: nodes are now coins you pick up as you pass,
  and the goal is a flag carried by our mascot
- Clear a board without Undo, Reset or Hint and its coins go into your total
  (top right). Coins grow in value as you advance: copper (Lv1-4),
  silver (Lv5-9), gold (Lv10+)
- Moves, vanishing lines, coins, switches and clears are now animated
- The default move sound is now Cowbell. You can switch back to Voice or
  Drum in Settings ▸ Move sound; if you already picked one, it is kept

### 1.3.0 — 2026-08-30

- Choose the sound your moves make: Voice, Drum, or Cowbell
  (Settings ▸ Move sound). Voice — the "ten-ten" and "boh" the game is
  named after — stays the default
- Drum is a TR-808 style kick and snare; Cowbell plays a short bouncing
  riff that loops every four moves
- The sound is purely a matter of taste. Boards, difficulty and every
  other sound are unchanged

### 1.2.0 — 2026-08-22

- One-way lines: a new kind of line you can only travel in one direction
- Every board is now measured for difficulty as it is generated, so each
  level plays the way it should — no more boards that solve themselves
- 18 levels with a proper ending. Clear them all for a COMPLETE!
- Earn a point for every clear without assists; 3 points advance a level.
  Points are never taken away
- New home screen: level mode and all four practice stages in one place
- Bigger, clearer boards with more space between nodes

### 1.0.0 — 2026-07-14
