The easy hashi sets are built so that there is nearly always a forced bridge waiting to be found. You will spend your time on the pleasant part of the puzzle — spotting an island whose count can only be met one way, drawing it, and watching the constraint ripple outward — rather than staring at a board where every option looks equally possible. It is the right level for someone who has understood the rules and now wants to build the reflexes that make bigger boards solvable.
Easy hashi boards with a moderate island count, printed with generous spacing so double bridges can be drawn as two clean parallel lines. Clue numbers sit inside circles large enough to stay readable once bridges meet them. Each puzzle comes with an answer page showing the complete bridge network. Black and white, single US Letter page per puzzle.
Three worth memorizing. An island whose number is twice its neighbor count needs a double bridge to each neighbor. A 3 with two neighbors needs at least one bridge to each. And any island whose number is one less than twice its neighbor count must have at least one bridge to every neighbor, because dropping one entirely leaves too few slots.
Can bridges cross each other?
No. Bridges may not cross other bridges and may not pass over an island. That restriction is what makes the puzzle work — a bridge drawn early can block a whole line of the board, which is often the deduction the puzzle is built around.
What does connected mean exactly?
From any island you must be able to travel to any other island by following bridges. It is not enough for every island to have the right number of bridges: a board that splits into two separate networks, each internally correct, is still wrong. Checking connectivity is usually the last thing you do.
Is hashi the same as Hashiwokakero or Bridges?
Yes. Hashiwokakero is the full Japanese name, usually shortened to hashi, and English-language collections often print it as Bridges or Build Bridges. Same rules under all three names.
