Few games embody the iOS indie-dev dream so perfectly as Matt Rix's Trainyard
. Its perfect trajectory from unknown puzzle game -- developed by just one man in his spare time for less than $1000 -- to number 2 paid app around the globe represents the aspirations of countless prospector game developers as they set out into the iOS wilderness.
Success came literally overnight. Trainyard
was released on June 10 this year, selling modestly till Apple featured the game in its recommended list a the start of October. The increase in sales the next day was astronomical, shunting the game from relative obscurity into the hot limelight.
Gamasutra's European editor Simon Parkin caught up with Rix two months after this crucial turning point to discuss the game's development, and what its gigantic success means for the developer's future.
How did you come to develop Trainyard?
I really wanted to do something that would bring me closer to my goal of developing games full time. I made games in my spare time on-and-off for my whole life, but the last time I released a game was over 10 years ago. I decided that I was going to take some steps to prove I could make a successful game, and hopefully bring myself closer to full time game development.
I developed Trainyard
whenever I could find the time. There were a lot of difficulties, slowdowns, and complete stoppages, but I never gave up. I spent a year chipping away here-and-there until it was finally finished.
What's your day job?
I work full time at a company called Indusblue
in Toronto. We develop iPhone and iPad apps for ďbig nameĒ clients. Itís a lot of fun and very challenging. Itís a small company with only 12 employees, so thereís often a lot of freedom to innovate and experiment. I actually started working there five years ago as a Flash developer, but over the past year the company has transitioned from the Flash advertising business into the iOS app business.
Where did the idea come from?
I was going through a period where Iíd spend all my commute time (on a train, of course) coming up with game ideas and prototyping them on my netbook. Iíve always had a love for colour theory and a love for logic puzzles, so I was trying to figure out with a way to combine them. I came up with the concept for a game called ďPaint TrainĒ which eventually turned into Trainyard
The basic idea was pretty simple: there are trains carrying different colors of paint, and when the trains crash, the colors mix. I played around with drawing train tracks on a grid, and finally figured out something that worked. Trainyard
is the only game Iíve ever made where the final gameplay was the exact same as I planned it out on paper.
What attracted you to iOS development?
There were a few key factors. The biggest one was that I knew Trainyard
would work fantastically on a touch screen. I couldnít wait to physically interact with it rather than play it with a mouse. The financial possibilities of the App Store were also very enticing. At the end of the day, my goal was to make games full time, and all of the massive App Store success stories made it seem like it really could happen.
It also helped that I came up with the idea for Trainyard
right around the time Indusblue was starting to investigate iPhone development. I would learn some iPhone stuff at work, and then go home and learn even more. That made the technological barrier to iPhone development seem a lot smaller, because at the end of the day, AS3 and Objective-C really are pretty similar.
What was the biggest challenge you encountered during development?
I think the hardest thing for me was staying motivated. There were times when I didnít work on the project for a couple weeks or even a couple months, so Iíd lose all momentum. Itís relatively easy to stay motivated when youíre working on game engines and particle effects, but when you have to rewrite all your Twitter authentication code for a third time, you start to question what youíre doing.
The game continues to unravel new design ideas across its duration. How did you come up with all these different variations?
Iím lucky because the mechanics of the game just seem to offer endless possibilities and variations. Throughout the puzzle creation process Iíd constantly discover new tricks and ways to use the basic pieces in different configurations. My process for creating a puzzle usually starts out with a very specific idea of what Iím trying to accomplish, whether itís teaching a user how to use a piece, forcing them to use a specific technique, or making an interesting pattern.
How much did the game cost to make?
The game cost very little to make. All of the development tools were provided by Apple and included as part of their $100/year iOS Developer Program. My main expenses were buying a $400 Dell Mini 9 Hackintosh, which failed miserably, and then replacing that with a $600 Macbook. I spent a couple hundred dollars on advertising, but thatís about it as far as marketing budget goes.
The game released on June 10th. Its rise in popularity was slow. Why was that?
The App Store is a chicken and egg scenario: the best promotion comes from the top sales charts, but the only way to get into the top sales charts is if you already have great sales. Itís very hard to break into the top charts without a lot of marketing, and marketing costs money, which I didnít have.
The other two things that can help are being featured by Apple, and to a lesser extent, being mentioned on TouchArcade (the largest iPhone game review site). Unfortunately neither of those things happened to Trainyard
in its first four months on the market.
What changed the game's fortunes? Can you outline is journey from obscure indie game to worldwide slash in the weeks that followed?
The big change was releasing Trainyard Express
, which was a free version of Trainyard
with 60 brand new puzzles created specifically for it. The free version quickly became very popular in Italy, then spread to the rest of the world, which lead to Apple discovering the original game and deciding to feature it.
Once the game was featured, I knew I had a unique chance to make a big move. I waited until the game was in the top 50 (October 12th) and then dropped the price from $2.99 to $0.99. I publicized the sale with a blog post
detailing the history of the game, as well as a post on Reddit. The story was picked up by a number of big tech and gaming blogs like BoingBoing, TUAW, Gizmodo, and Joystiq, and the game quickly shot up the charts to reach the #2 position, overtaking Angry Birds
Chart showing sales before Apple featured the game, and after.
What proportion of Trainyard Express downloaders bought the paid app?
Unlike most popular iPhone games, I donít have any analytics or tracking in Trainyard
, so I donít have precise numbers on this sort of thing. I can only go by what I hear on Twitter, which is that quite a few people have finished Trainyard Express
and upgraded to the full game. A general rule of the thumb in the industry is that 2 percent of people will upgrade, and I imagine thatíd be pretty accurate for Trainyard
About how many sales do you make a day at the moment? Has that tailed off?
The sales have dropped off considerably from where they were a couple months ago, but theyíre still substantial. Iíve raised the price back up to $2.99, and Iím currently selling approximately 600 copies per day.
Where next? Both in terms of Trainyard and possible future developments?
In January Iíll finally be following my dream and starting my own game company. At first itíll just be me working from home, but Iím hoping itíll gradually grow into something bigger. My first order of business will be working on an update for Trainyard
. Iím planning to include a mode for users to create and share their own puzzles as well as adding some other cool features.
After that, I have a bunch of potential game ideas to work through. One is a puzzle game thatís somewhat similar to Trainyard
, another is a platforming game thatís like Canabalt
mixed with Tony Hawkís Pro Skater
, and thereís even one thatís a two-player co-operative iPad game. As much as I hate to say it, Iíd also like to look into social games and see if thereís a way I can create one with true depth and complex gameplay while still appealing to the casual demographic.
What lessons have you learned through this process?
Iíve learned a ton of lessons, but the biggest one is to pick a goal then follow through till youíre done. Youíve got to be motivated and determined to finish your game, or else you just wonít. I see way too many people biting off more than they can chew, attacking huge games or just working on prototype after prototype ad nauseum. I think youíll learn way more from finishing and releasing a single game than youíll ever learn from working on dozens of prototypes.
Do you have any regrets or anything you'd do differently?
I really donít have too much to complain about, but I think my main regret is just that I didnít do this sooner. I wish Iíd started learning about the App Store the moment it was announced rather than waiting a couple years, but thatís just how things go. I also think I should have released Trainyard Express
sooner rather than waiting four months. I donít think itís a good idea to release a lite version at the same time as the full game, but waiting four months is just ridiculous.
