[APP] Checkers and Reversi Pro

Hi, it's been 20 years since I developed for a living, so wanted to get back in the game with the WP7. With VS 2010, and a couple of free books (Charles Petzhold C# and WP7 books) I was able to create two games (Reversi Pro and Checkers Pro) - both with free versions, and launched them a few weeks ago. It has been an interesting experience. Here is my blog, with all the (long) history, and 'inside scoop' about developing each of these games:
//berzamora.wordpress.com/
So far they have had more than 30,000 downloads in the past 5 weeks! (and both programs are in the top most free downloaded games). Each game has had several revisions, and there are many lessons learned about developing for WP7 for a newcomer. I tried to tweak, optimize, and in general make the AI in each the best one. I got an iPhone loaner, and purchased all the equivalent games in iPhone and played game after game vs all of them to compare strength... in the last version of Checkers Pro and Reversi Pro, they match or beat all the other iPhone games in their highest difficulty - iPhone users, you've lost the crown!
CHECKERS PRO
Interesting facts about Checkers Pro: It can now do the equivalent of 900,000 board evaluations per second (in a Focus WP7 phone, incredible how a simple phone can have so much computing power!). BitBoard algorithms make the game very fast and compact. Top features users request: undo, no forced jumps, save (tombstone) state, nice graphics, and online play (online play not implemented yet). I have never beaten it in Grand Master or Impossible level.

REVERSI PRO:
Interesting facts about Reversi Pro: I focused on making the graphs very simple and clean (with all the plumbing and complexity hidden), and the result ended up (surprisingly) being very good looking and users like the simplicity of the layout. Even though the algorithms are not as fast as Checkers, I had the phone play more than 80,000 games against itself, with different board evaluation values, and after these games it produced a had a matrix that identified the best possible values to use to have a strong game. I have never beaten it in Grand Master or Impossible level.

ENJOY THE GAMES!
P.S. If anyone has 30 minutes to help me create a very simple webservice that I can later deploy in a hosting site, and I can access though the WP7 phone, please contact me: berzamora at yahoo.com

Drastic DS (Nds emulator)

Hi 4x HD users,
I found a app that runs ds games almost whitout lagg
I played mario kart, super mario bross and pokemon black almost whitout lagg :3 (haven't tried other games)
Here is a playstore link : https://play.google.com/store/apps/...google&utm_medium=organic&utm_term=drastic+ds
The app cost 6,99 euro ( i dont know how much dollar that is)
Al thanks go to the developer(s) of Drastic DS
(Sorry for my bad english i want to share this great app, what i find on the xperia play forum)

I have been playing on this for a while now, seems to run poorly on CM 10.1 & 10.2 stock kernels but once you change kernel to anything else it runs almost flawlessly, even while underclocking the CPU to 1,2 GHz.
The game i used to test this emulator was Pokemon Black (1) but i have also played Pokemon SoulSilver, Okamiden, Phoenix Wright Ace Attorney, Pokemon Diamond, Pokemon Mystery Dungeon Explorers of Sky and Rhythm heaven on it and they run with no problems.

Excellent it is.
I've been running on both CM 10.1 and 10.2, with stock or prime kernel. It runs pretty much the same. Edit: That is for FF tactics A2, Tales of Tempest, Shin megami Series, Castlevania: Order of Ecclesia, Suprisingly Chrono Trigger compared to the awful version on google play lol.. Oh yeah Fire Emblem: Shadow Dragon. Except for very few times when i push the menu on CM 10.2.. The App goes out of the game to the loading menu screen. Im sure with the updates.. It will not do that anymore.. I also clock it on 102 - 1200mhz too with Dithering disabled, 128/ 256 VM heap size. It is a great app despite its alpha stage.. (Minus Suikoden, and Golden Sun)

THanks man! Finally i can play pokemon again without buying a stupid DS

How to monitor your app in first few days?

Hello everyone,
We have launched an android app, Factor Monsters (by Knowledge Platform), yesterday. Google Play is not showing downloads as for now and I came to know that it will show number of downloads after 2-3 days.
I am curious that, in such case, how can I benchmark our app's performance? We have received 30 ratings so far. Are they a good start? Is there any benchmark or tool to determine if our app is going fine or not?
I tried to do Google Search but was unable to find any answer which can give this information.
I shall look forward to learn from you in this regard.
Best,
Hira

Once and for all. Remember one thing. You should integrate analytics services into your app to get prorper information and on time.
30 is rather good but the amount of marks rarely indicates the amount of downloads. I would suggest 100-500 in your case.

You would suggest 100 - 500 of what in his case? Downloads?
Usually, you can expect that less than 0,5% of the users will review your app, and that 1 - 3% will give you the rating. Top games (Clash of Clans) get up to 10% ratings. But with such a low data, anything could happen. Also, many things could affect them:
- have you reviewed your app? With 30 reviews, your review is 3,3% of all your reviews...
- have your friends or family reviewed your app?
- have you asked people to review your app?
Anyway, good indicator would be to check how many impressions have you generated. Ad providers are much quicker with their dashboard updates. Also, integrating Google Analytics or Flurry could give you detailed insight in your users count, session length etc.
If you got 30 unincentivised reviews from general audience (not your facebook friends etc) it would mean you are most likely in 5000+ downloads range. But I guess you got these reviews from your friends or people that are somewhat familiar with you, and you are in 100 - 500 downloads range. Anyway, you can't expect any detailed and accurate data with such a low reviews count.

Hey hzainab,
30 ratings is a good starting point for just 2/3 days on the store, but as others have stated, I would wait until you have reached a higher volume if you want to use ratings as a metric.
I would focus on getting to know my users and the retention. Ratings may be good, but have you wondered how many of your new users have returned to your app after the first session? Or even if they are using the app the way you intended? Who are they? How much are they using? These KPIs will be more important on this stage since they will allow you to fine tune your users experience.
Google Analytics or Flurry can be an option and they are free services, but they will just give you some (limited) information. Since this is a newly app and you probably don't have a gigantic user community already, why don't you try other services which will also be free for your current numbers?
I know I am biased because I work for Liquid, but I would suggest that you take a look at what we do.
Regards and much success.

Yep, downloads. Usually you get bigger review\download rate in the beginning because of friends review , friend of friends review - etc. One crappy game of mine got 60 reviews and less then 700 downloads

Hi, You can choose App Annie, App Figures or Flurry to track your apps performance.

We used Google Analytics and BugSense.

Tips to monitor your app -
1.Firstly – don’t only focus on app downloads!
2.Want to improve your app? The real data is about engagement!
3.More behavior to track? Push notifications!
4.Track those all important reviews and ratings
5.Depressing uninstall analytics – not to mention crash stats!
6.User Acquisition – where did a spike in downloads come from?.

Below is the data you need to track immediately after launching:
New users from acquisition sources
First-week engagement rates
First-week retention rates
Most used features
Least used features
App-store views and ratings
App installs vs. churn
Glitches/bugs

Help! My Google Play app is being spammed with hundreds of 1-star ratings!

This has been a nightmare for me tonight, watching my app go from a 3.9 rating to a 3.7 in a matter of hours.
I regularly monitor my app's statistics in both the Google Play Developer Console and an app called Andlytics. I look at my average rating, reviews, downloads, app crash logs, etc. Being intimate with my daily numbers, when they start to change drastically, I can easily spot when something is off.
On 11/7/2015, I got hit with numerous fake ratings and reviews. I received a total of 52 1-star ratings for that day, which is about 30-40 above average (I average about 5-20 1-star reviews a day). Other than the countless negative ratings, nothing else was abnormal (normal downloads, normal crash logs, etc). After reading a few of the reviews they happened to leave, the picture became clearer... all of them came from the same handful of devices, and every single one of them had the en/RU language set on their device. I went ahead and flagged those reviews as spam -- so far they are still there, but fingers crossed that they will go away. As far as the ratings go, I am unsure of how to view and flag the individual ratings (reviews left without comments), but I am absolutely sure that they left some of those as well (by my count, at least 10-20). Here are some screenshots I was able to take of the reviews...

A few days went by with no strange activity. Until on 11/15/2015, I again was spammed like crazy with a whopping 613 1-star ratings! No reviews were left this time -- only ratings. And again, besides the avalanche of bad ratings, other app statistics looked normal (normal downloads, normal crash logs). This time around, I knew exactly what was going on, as I had read about it a few days prior... Apparently there are services out there where users can pay for thousands of fake reviews on a competing app, to ultimately lower its ranking in search results. Notice how in the screenshots below, the 1-star ratings go from a 277 at 9:20pm, to a staggering 609 at 10:12pm! In less than an hour my rating had drop 0.2 -- from 3.9 to 3.7 -- in comparison, my usual rating change for a day is a +- 0.001... By the end of the night, the final number of 1-star reviews settled at 613, as seen in the third screenshot.

As you can see, I am clearly being attacked -- most likely by a competitor who wants to get their app ranked higher than mine. I believe that 100% of these ratings (minus the normal 5-20 daily average) are falsified, and would like help in getting them removed from my app's rating. Every moment they stay, it hurts my app's reputation on the Google Play Store.
Does anyone know the best course of action to report these fake ratings? There are several resources on the Google Play Developer help section, but they simply tell you to flag the review -- unfortunately you cannot flag reviews that were left without comments -- which the majority of mine are. I did fill out a generic form for support, but I have no idea if I'm actually sending to the right people. Anything you guys know would help!
Thanks,
-Jake

Hi all, my first post, and I've just got my global NOH-NX9.
Tried a few games w it.. it seemed like most of them looks pretty bad like in 640x480 on a high res screen.... (my reference comparison is my mate20). My stupid question is, is it because these games are tied to GMS some how?
Asphalt9 is the only normal looking one.....
(tried honkai impact, genshin impact, csr2 and some other random games)

I think those games you mentioned have compatibility issue with the new Mate40, can you try some more popular game such as Clash of Clan, Brawl Stars and LOL Wild Rift? They are not available in the Huawei App Gallery but should be able to download from other app stores

Thanks, I go try the others. Unfortunately, tried downloading LOL WR.... doesnt allow me to install (via peta)

Take it from Aurora store.
I just installed to check ...
