[Android] Quadropoly - Free with Ads, Quadropoly Pro - $2.99 (Was $9.99) No Ads No IAP Full Functionality @ Google Play

280

G'day guys,

It took me half a year since my first attempt to release this app on Play Store to improve it based on user's feedback. I am still very far from being done, but in regards to what it was 6 months ago - almost nothing left from the original version, with the number of features expanded manyfold.

The main feature of the game is AI. This is the first attempt to build Artificial Intelligence with Machine Learning for Monopoly, and the third in the World for any game, the first and the second being Deep Blue for Chess and AlphaGo for Go. AI for Monopoly is much harder to implement though as there are 4 players instead of 2, and the Dice add the element of random, making brute force calculations of any possible combinations useless. It took me over 2 years to get that far, and the AI improvement is an ongoing process.

These are the main foundations Quadropoly has been built on:
🔵 No cheating. No re-rolls, every dice roll is final. No hidden luck parameters used by others, regardless of the difficulty. Pure data science for Machine Learning versus your skill with guaranteed random dice rolls
🔵 No preferential (discriminatory) trading for AI. This is the second trick others use to lift the difficulty. In Quadropoly, AI does not know whether their trading partner is another AI or a human, regardless of the difficulty: trade offer evaluations depend on pretty much everything on the board at the moment of trade, but not on who their opponent is

There are 5 difficulty levels at the moment, so you can stop on a level you feel comfortable with. You can also use AI advice system, which would guide you through many tactics, show trading opportunities and help estimating every trade at any point in game. This is designed to help anyone to learn and improve up to Monopoly Tournament participation level. Every single AI in every game is unique and has its own personality which defines its risk taking or risk averse tendencies as well as the attitude towards property. AIs are great at imitating real people: they could be annoyed, desperate and greedy as well as 'feel' a range of other emotions. The main difference is the fact that AI is not going to through their game piece at your face when it is about to declare bankruptcy :)

Game is highly customisable - you can change many rules and parameters, select or remove chance/chest cards any way you like, enable some or all house rules, or even play with external (physical) Dice. You can also choose to play in horizontal or vertical layouts, change the game speed and many other options.
The game contains extensive Rules and features description section, as well as in-game tutorials explaining User Interface and basic functionality.
Quadropoly does not contain any adult material as such and can be safely given to children who could learn a lot from it. However, the game is primarily created for highly intellegent adults who appreciate true challenge of smart AI and quick gameplay (10-15 minutes per game on average), rather than cheap flashy animations and easy (but very lenthy) wins.

There are 2 version of Quadropoly available for Android right now:
1) Free trial version with ads (no popups in the middle of the game) and limited functionality
2) Paid full (Pro) version with no ads

Neigher version has any microtransactions. I would suggest starting with a free version here: https://play.google.com/store/apps/details?id=au.com.quadrop…

If you like the game, please support my further development efforts by upgrading to Pro version, especially while it is on sale: https://play.google.com/store/apps/details?id=au.com.quadrop…

Even if you have seen the game 6 months ago, please give it another GO - pretty much everything has been reworked from scratch after 22 major and countless minor releases (full list here: http://quadropoly.com.au/app-releases/ )
Any questions, suggestions or bugs are always welcome, either here or at [email protected]

May the Dice roll always in your favour ;)

    Good on you for all of your efforts in producing a game, and OzB is definite a great place to get it out there.
    Supporting the homegrown commitment.
    All my blessings for future projects and programming!

    • Thanks a lot! I am from Melbourne, and the board is based on Melbourne suburbs with other states planned too. It is hard to get more local than that :)

    Free with ads is like free blood transfusions with aids tainted plasma cells

    • +4

      You have the choice, free with ads, or no ads if you pay.

      Sounds fair to me - how else is a developer supposed to make money? I've tried giving games away for free and living on love, but eh, my belly rumbles when I don't have food.

      • +4

        Exactly. The only other way to pay for hosting, cloud storage etc is to include data mining SDKs which would collect your data for whatever reason. This is way worse than ads in my book. And I am not showing popups in the middle of the game, as almost everyone does.

        • oh elaborate more on the data mini SDK? Are they paying you for the data you gathered?

        • @h4zey:
          There are companies who do pay per active user per day as their SDK collect data about user's phone, location (the most important data for them) and who knows what else. I am not using those SDKs, so noone pays me anything :) The best way to learn whether an app has those data mining SDKs is to check if app requests location permissions. I am not a specialist in that area, but I have been contacted by sales people from those companies - never even replied once I learned what they are.

        • @CutMeOwnThroatDibloh: thanks for this, do they monitor your usage in the background regardless if you use the app or not?

        • +1

          @h4zey: I cannot say for sure since I have not tried to use it. But I guess the answer depends on whether the app is allowed to run as a background service (i.e. some apps run even when minimised and send you notifications when some event happens, like new multiplayer game available or something). If it is, then it is possible to collect data even if you close the app. Quadropoly does not have background processes and fully paused when minimised.

        • @CutMeOwnThroatDibloh: I used to have my phone rooted and could see when apps accessed the GPS, sent/recieved data. I removed most of my apps after that.

          Eg. why the (profanity) does IMDB have to get my location and then send data a few times per day, when I only open it like 1x / month?

          Uber is another offender, randomly pulling up my location and accessing the network when I haven't even opened it that day, but unfortunately I depend on it :(

    Bought it just because its on OZb and i like supporting home grown, ta.

    ps: this post effort alone looked like it was worth $3.

  • +1

    I've been playing this since the dev released it many months ago and love it. I think I've played about 150 games. The AI is getting very challenging now, I used to get a 25% success rate on Monopolist and now I haven't won a game in a very long time. Luckily there are many levels of difficulty in order to have a break on an easier level.

    Sometimes the app gets some bugs after a set of improvements, but the dev updates it frequently because I see that it's always on my update list, but those bugs are always fixed. The latest set of updates has improved the graphics, and a dramatic improvement has been made on the speed it seems. Thanks!

    BTW it would be nice to have the landscape mode also work on the opposite side. Seems fixed on one side only.

    • +1

      Thank you! In regards to the landscape side, this has been requested a few times. I am still looking into it, but so far I could not find a technical possibility for my platform. But I am learning a lot, often improving the core structure of the platform itself, so eventually I hope to be able to do it too.

  • +2

    Post + great username made me check out. Looking forward to trying this after work!

  • If only there was an iOS version. Would buy, love a challenging Monopoly.

    • This is definitely coming, I am just trying to finish off a very active development phase having to support just one platform for now. Working on two simultaneously would be too much. I will try to publish it on App Store in the next 6 months or earlier. Thanks!

      • Are you using a toolset that will allow targeting different platforms from the same assets and code?

        If you are, ignore me, if you're not - there are drawbacks, but the benefits can outweigh them for some games.

        • +1

          Yes, it is written in Python & Kivy, which allows building most of the code unchanged for iOS. The iOS support for Kivy is much worse though than for Android, so there will be issues to deal with. Having to resolve them for every new version (which I do almost weekly) would be taking up too much time.

  • +1

    I bought this mostly because it has Melbourne suburbs in it :)
    I'm guessing OP lives in the south eastern suburbs.

    • Thank you! You've got it right, I live in the most visited suburb on a board - 8 steps from the Prison :)

  • +1

    You had me with "You are imprisoned for selling yesterdays donuts to the policeman. Go to PRISON" haha bought. Agreed on you with the ads too. I don't mind banners.

    Tried this when it was brand new. back then it was rather buggy, won the first game and it would crash as all the players went bankrupt. Much better now. Only issue thus far is the "AI head" covers up the $ values sometimes, insignificant.

    • Thank you! It gets rather hard to find a good place for every UI element as the screen is extremely busy. I will think about changing that though. Thanks for the tip!
