a2Ropes
A game on zen2play
Tie the towers. Connect them all.
a2Ropes is inspired by the classic Bridges logic puzzle. Every tower holds exactly as many rope ends as it has floors — tie one or two ropes between neighbours, never cross a rope, and join every tower into one network.
- 6×6 and 8×8
- Medium and Complex
- Exactly one answer, no guessing

A solved 6×6 from the game, seen from the top.
Four rules
The towers stand where the puzzle puts them. You only tie ropes.
The floors are the clue
A tower of 4 floors holds exactly 4 rope ends. A double rope counts 2 at each of its towers.
Straight, to the nearest tower
A rope runs along a row or a column to the nearest tower that way. Two towers share no rope, one rope or a double.
No crossings
Ropes never cross each other and never pass over a tower.
One network
From any tower, a path of ropes reaches every other. Loops are allowed.
Playing
Tap a tower: a rope hangs from its roof. Tap a lit tower to tie it, or drag the loose end there. Touch a knot to cut that end loose; touch the tower a rope hangs from to drop it. Turn the board, or look from the top.
Every puzzle can be solved by thinking
Each puzzle has exactly one answer, and you can reach it by reasoning alone — Complex puzzles need one “what if” along the way, never a guess.
