Tentenbou: Dots & Bars Puzzle

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?
