Hashi is a grid-based logic puzzle that can be solved by logic only, similar to Sudoku or Kakuro. Hashi is also known as Hashiwokakero or Bridges. The puzzle is invented by Nikoli, a Japanese publisher that also invented the most popular logic grid puzzle of all: Sudoku. With Hashi, they have developed another puzzle that is at least as challenging and addictive as Sudoku. All puzzles in this app are produced by brennerd. brennerd.com/puzzle_games

Hashi Puzzle user reviews :

How nice to find a well designed and professionally laid out game, which makes you seriously think, what looks easy is not necessarily so, there are hidden pitfalls all along the way. It is great that you can do these when you have a few moments to spare, and each one is challenging, very well done, thank you.

Nice game! Great build-up of the difficulty, easy ones for beginners, but the tough ones are seriously tough

The puzzles are well-made, tricky and super good. I love the fiendish levels very much. I think there is a bug in the timer. It shows 33:31 min when I solved it in 3:31 minutes. Edit: The issue is now resolved. Thank you

  • Thanks for your review! And thank you very much for reporting the timing issue. I finally found the bug causing it and fixed this in the latest update.

Well-built logical game which makes you think a lot. Like it so much.

This game is challenging and fun at the same time. Enjoyed playing it.

Nice app, but a few minor problems. There’s no grid, I wish there was a feature where, if I tapped a node, I could see the all of the other nodes it could potentially connect to. If I held down a node, I could see all of the other nodes it’s currently connected to – that would help a lot with visualization. also, I’m fairly confident that Difficult Puzzle #2 is unsolvable, I’ve tried it multiple times with hints, but I don’t think that configuration has a solution.

  • Thank you for your review! If you tap and hold a node, all connected nodes will be highlighted. I like your suggestion of highlighting neighboring nodes on tap, I will consider adding that feature. Difficult #2 is maybe a tough one, but can be solved. If you are really stuck, you can always send a screenshot to bbrennerdd[at]gmail.com for help.

This is a wonderful challenging game and it has been well implemented. I am currently enjoying the fiendish levels which keep my mind engaged. It’s a great feeling when you manage to solve one of them. Recommend to all who enjoy a challenge.

excellent! Well made difficult ones that can be beaten with logic rather than trial and error. Also the game only asked for this review after completing 100 difficult.

The hint feature makes it a lot easier to get into. There’s no punishment for taking hints, so it’s kind of like a tutorial you can engage with at any time.

An amazing brain puzzle game. A good way to develop skills and addictive as well,.

Very tricky puzzle game, I really was clueless about possible solution of some levels. Think about adding hints)
  • brennerd
  • Thanks for your review! They are hidden away a bit, but you can always ask for hints using the menu in the bottom right of your screen.

Very good game , with good graphic design and exiting play , interesting game
