What’s New

Version 1.38.0

Some small corrections and enhancements. The changes in detail:

- The page showing the outcome of a puzzle now includes summary information to describe the puzzle just played (this is shown at the top).

- In the performance analysis, the analysis at group level now shows the average points for the puzzles in a group, instead of the total points.

- Long help explanations can now be scrolled. This ensures that the explanations are able to fit within the display space available.

- In Random Play, when the setting for selecting the size of the next puzzle has been turned on, a new option lets players choose to see the outcome page of the previous puzzle when Random Play is first launched. This makes it possible to select the size of the first new puzzle to be generated.

- Also included: some cosmetic improvements, a fix to the way the candidate values for empty puzzle squares are determined and more corrections to the help explanations.

Perfectly challenging

Sumaddle is a great game for fans of number puzzles. I was looking for something that was a little more challenging than sudoku, and this game really delivers. I was more than happy to pay the couple dollars for the extra puzzle sets and the endless puzzle option, and it’s continued to keep me entertained for several months.

My only criticism is that I sometimes get penalized for “using help” even when I haven’t asked for a hint. It seems to happen when I am trying to remove a number from the possible options in a box, and I double tap the number. If I’m too slow, the game thinks I meant to put that number in, it tells me that the number is not a possible option for that row’s sum, and then I get docked points. It can be a bit of a killjoy when you’re proud of finishing a puzzle, and then you get the notification, “Your score would have been higher if you hadn’t used hints.”

Other than that, it’s still a 5-star game, and it will remain a staple on my phone.

Hi preiring and thank you for your great review!

Interested by your comments about difficulties with number elimination using double tap. The double tap does not need to be done quickly, you can actually take as long as you like. So I'm wondering if the problem might be, that you're missing the number altogether with your second tap?

UPDATE: Just to let you know that version 1.29.0 has gone live in the App Store today with some improvements to button sizing. This should make the buttons easier to hit or, more to the point, harder to miss. The change benefits large devices the most (larger iPhones and iPads), hope this includes you and you find the problem happens less. Thanks again for your helpful feedback which is what prompted this change!

Ps. The FAQ at the support site provides more detail about how using the help can impact the scoring, if you're interested. A link to the FAQ can be found by tapping the info icon below the main menu.

Enjoyable and Helps You Build Your Logic Skills

One of the best aspects about this game is the hint function! Starting with just telling you whether everything on your board looks correct or if there appears to be an error somewhere (if so, you get the choice of just removing the wrong bits, restarting from scratch, or undoing some of your last moves and seeing if that fixes things), asking for more of a hint tells you what row or column to look at for your next move and shows you the possible combinations of numbers that equal the sum for that column or row, and asking for additional help pencils in the available options for each cell in that row or column, with the option to view an explanation of how you can come to such conclusions. The only downside is there is no option to selectively pencil in notes for yourself beyond whether something is a number or a block. Sometimes I can eliminate certain options for a cell myself, but without being able to selectively pencil in numbers, I can’t keep track of those unless I keep them in my head (difficult to do when I still see those eliminated options penciled in) or write them down on paper. Please add an option to shift between pencil/notes and pen/confirmed modes!

Hello Paise19 and thank you for your positive feedback! I am pleased to let you know that the app does in fact have a pencil mode. Previously, this was only available to Random Play players. However, as of version 1.18 it is now available to all players! This version has gone live in the App Store today. I hope it gives you the functionality you were looking for.

Well designed all around

I don’t think I’ve ever written an app review before, nor have I paid for a free puzzle game, but this one is so good I’m doing both.

The number puzzles themselves are good in the vein of ken ken, skyscrapers, or the like. What makes the app shine is how easy the interface is. Adding or removing possible values from a cell is super intuitive, and it automatically tracks possible values for a given cell, so you don’t have to do it yourself all tedious-like. And once every cell has only one possible value remaining (because you entered it or all other values are shown eliminated) you’re done! Again, a great way to avoid the tedium.

Finally, the game has no ads! No obnoxious bar at the bottom of the screen, no pop ups between levels. I appreciate all of this so much that I threw the developer some dollars. What a delightful, clean app.
