Fixes a bug where, under certain cases, an incorrect cell responds while playing a resumed game. This is now resolved.

User reviews

No save progress

Fun game. However, 3 times now my game has been reset mid game, hours into progress game stops working. Do not shut off app while in mid game, it will not save state. Frustrating to lose game over and over after hours of play because developers are lazy. Do better jeets

Removing incorrect entry

The directions you give for deleting an incorrect number doesn’t always work. This is extremely frustrating. Is there a way to fix this?

Missing useful functionalities

From a near zero failure rate on difficult level 9x9 grids (played on other apps) I now have nearly 50% failure rate on your 16x16 medium level, to the point where I’m now doubting the app itself!
The following features would be really helpful add-ons:
1. a « Backstep » button;
2. an error flag (on/off setting);
3. a « Show all errors » button;
4. a « replay grid » button.
The Notes button should be bigger; half the time I have to repeat entries because the button hasn’t triggered on/off, even on the larger view iPad. Ideally two separate keyboards should be available, one for notes, the other for actual entries, if the screen real estate can accommodate this.
Otherwise I’m happy with the 1-16 numbering, but offering 1-9 + A-G as an option would make the app more appealing to some players.

Some good some bad

Like the layout but no way to change notes when you know it can not be those numbers. Should be able to edit notes easily. Could not navigate the use of the control buttons when they are used for different things by how many times you punch or hold. Too confusing.

Response from developer

You can enter or delete notes using the following steps: 1. Pressing Notes button enables/disables Notes editing mode. 2. While in the Notes editing mode, select a number that you want to enter or delete in notes. 3. After that, pressing a square will a. Enter the number as a note if it is not already there or b. Remove the number from notes if it is already there. 4. You can also long press Notes to remove all notes.

Thank you

Thank you for creating those grids. They are my favourite and they are so rare!! I can’t imagine how hard they are to create. The highlight also really helps compared to a paper grid. My only request would an option to have # 1 to 9 + letters A to G for 16x16 grids, instead of #1-16, but that’s only because that’s what I’m used to. Thanks again!!
