Number Knot

Sometimes known as hidoku or hidato, you are given a sparse grid with just a few key squares pre-filled. You must then fill in an ascending sequence of numbers going sideways or diagonal.
Play 36 levels of different size grids for free with no adverts!

If you enjoy the free trial, buy the full game or some keys to unlock more than 600 levels ranging from easy 3x3 grids, or tough 12x12s
- best played on tablets.

No timers, music or annoying sound effects
- take your time and take on the challenge of the Number Knot!

Tip: There's no need to start from 1 and work all the way to the end, you can jump around and fill in any easy sections first and join them together at the end.

I'm not sure what happened, but apparently it's lost my progress, tapping on the grid doesn't always change the selected cell, and the whole thing is suddenly harder to actually complete. Add to this the fact that the Back button is in an odd spot (right beside the Restart button), and the fact that it plays an ad every single time you go back to the puzzle selection screen (whether you finish the level or not), and it's far more frustrating than it's worth.

The concept is simple, but many of these puzzles can be almost infuriating to complete. The range of complexity is very wide, which means there's one to fit any state my brain finds itself in. Addendum: Having owned this game for well over a year, I'm still coming back to it. I've gotten far better and am ready for a level beyond the red now. I hope the developers introduce one soon.

Great logical puzzles. Some can appear easy but then you may get stuck and have to change your answers. Software error: none of my hinter achievements have been rewarded despite achieving them. Sometimes I use hints but they are not counted towards the hinter achievements until I leave the game then open it another time. I have become a master achiever, therefore I should have hinter achievements. I have not been rewarded my master achievement either despite achieving it.

Love this game, had to stop playing though since unlocked levels on previous phone won't transfer to new one for some reason 😭 but it's a great game if you love number puzzles. Definitely makes you think and can be a good time consumer when you move on to difficult levels.

I don't know how else to ask a question other than to write it on the review. I absolutely love this game!! LOVE! That being said, something is not working on my phone on this app. I don't know how to fix it and I really would like to still play it. Can you tell me a way I could communicate my issue with the developers? I can't text what all I want to on the review cuz it's too long. Please help!!!

Way too many not skipable ads during first level. I got 7 ads within the first 12 fields. Game destroyed because you never get into the groove...

Good game - reasonable UX missing a few possilities such as an 'undo' that allows you to rollback X moves. Be nice to be able to drag from one number to another number and the inbetween numbers get filled in...

Redownload on a new phone, game is broken because none of the other levels are unlocked but when I do use a key to unlock them they are already completed from the last time I played but doesn't give me keys to unlock new levels

Great game, but needs more free levels. I got through them all in a couple days.

You just can't say no to this. I've used more than 5 different phones. Everytime I just had to install this game

contains too many ads. after every level you have to watch 30 sec ad. and that's very rubish

This game this a lot of fun, which gets very challenging as you get past the levels.

Nice game, good time pass, some times twisted hard even though enjoyable, it makes mind free

Very addicting and thought inducing. Can easily kill hours of down time.

Too much full screen ads... 30sec full screen ad after every 1 min game is ridiculously annoying...

A. G. u. Apr 4, 2019     

I enjoyed the game. I have four keys left. There is no way I can use them . I have played all the games. So what can I do with them ? I thought I would get more games ,to use them.

I was playing great number puzzles with the best scores.

I love this. Only criticism is the awards given, not using hints limits the me to an apprentice. When will there be more levels released? Please say soon :)
