### 2/5 — Too many solutions & no notes

*2020-06-06*

The ability to take notes is necessary to solve this type of puzzle. I’ve had to recreate the puzzle by hand, but even then the puzzles have either not enough information to solve without guessing or have more than one solution.

### 3/5 — Needs pencil marks

*2020-02-26*

Clean and simple, but definitely needs a pencil option. Also, I would prefer an undo option as apposes to a complete revert to start button.

### 2/5 — Needs a pencil option

*2018-09-21*

I love this puzzle and I like the design of the app, but it really needs a pencil option.

### 1/5 — Garbage

*2016-02-04*

Only 5x5 is available. Can't pencil in numbers. There are much better versions out there.

### 3/5 — Yes and no

*2016-01-03*

So happy to have found my favorite type of number puzzle in app-form. On the other hand, really wish there was a "pencil in" option and a way to check progress as you go. As it stands, it is fun and satisfying to a point but would pay for above-mentioned upgrades.

### 5/5 — Love!

*2015-10-01*

My new favorite app

### 3/5 — Good but needs improvement

*2015-09-27, version 1.1*

Fun but could do with a better hint system - currently you see the entire solution if you ask for a hint. Would also be nice if you can put pencil marks in so you can see your working.

### 4/5 — A fun game

*2015-06-20*

The only thing missing is an undo button.

### 5/5 — Really good

*2015-06-04, version 1.1*

Good

### 4/5 — Help???!

*2015-03-15*

Purchased game and completed first 2 sections (9+9) but cannot advance, says complete more tours but there are no more!
