Zeroes is puzzle game for Android. Your goal is simple. Make zero on each dot! How to prove it? By placing blocks between dots with numbers. There are several types of blocks to use. Blocks with plus, minus, multiplication or division, horizontal, vertical and diagonal, shorter or longer. You have to use them all to solve every puzzle. But you have to use especially your intelligence to succeed in this logic game! Why did I created such game? Because I want to show you, that math can be fun and beautiful, when you can play with it and experiment. Math is not that monster, which all of us remember form school.

Add sounds and music!


I have already added some sounds during summer, but it was necessary to add more sounds. Sounds add another layer of informations to player. There was also no music. Adding them seems easy at beginning. Search through databases of free sounds, choose some sound effects and put it into game.

The first problem come early. Many sounds and music are free for non-commercial projects only. It wouldn’t be problem if I knew, that Zeroes will be 100% free. I am still not sure, but it will be free probably. I just want to keep back doors open. Another problem was, that there are too many sound samples and a lot of them are low quality. It is literally like looking for needle in haystack. When you are choosing some picture, it is quite fast. You immediately see whole image. But this is not the case of sounds, no no. You have to listen ideally to whole sound to check, whether there is good part. And it tooks some time.

I ended up with very few sounds and no music after searching through free databases. Another solution was to create my own sounds. Great idea! But I have no capturing device. Phone and cheap microphone doesn’t count. Only one solution left, to open my wallet and buy music.

I have to say, that commercial databases were much more comfortable, faster and I founded suitable sounds almost immediately (not so immediately actually, but faster than on free databases). You can download sound for free with some voice over it, to try it in game. So you can get quite good image how it suits to game. So far so good.

I didn’t pay much attention to prices. What what a mistake! My main goal was to find most fitting music to Zeroes. I was looking for something funny, energetic but not much disturbing. I founded three music tracks, which I thing fits game very well. One is for each world. Great, let’s go buy them!

Price of sound effects was quite fair. About 1$ or 2$ for each. Problem was price of music. There my wallet really hurts! They wanted 40$ for the first two tracks and 18$ for the third one. But I decided, that it is better than to spend my money in pub or for cigarettes. And I will be showing this game to my grandchildren maybe one day :D . It showed up, that 40$ is without vat, so final price was 48$. Really great, I am thankful that I have summer job. But result is worth of it (at least for me)!

To implement sounds to game I used new Unity’s Audio Mixers. You can use it since version 5. It is quite easy to use and powerful. I used only volume changing and some high and low pass filters, but there is much more settings which I don’t fully understand. I can imagine, that some musician can do interesting stuff with it.

What lesson I get? I should get better not only at making graphic but also at creating sound. It can save money! Excuse me now, I’m going back to creating the game. You can meanwhile like new Facebook page www.facebook.com/ZeroesGame or follow me on Twitter www.twitter.com/er_mrk.
