You Should Be Making A Premium Flash Game

Are you trying to make flash games for a living, but having a hard time making ends meet? Have you made an engaging & fun game, then spent months polishing and tweaking it to perfection before releasing it onto the world? Maybe you got it right and it's a hit - it's been played and enjoyed by literally millions of people! Well time to sit back and watch the pennies roll in, my friend, because that's all you're going to be getting. This may sound alarming, but it's what most flash game developers have experienced using what I call the 'Ad Model' of monetisation.

All this could be yours!

The Ad Model

Over the last few years Flash gaming has enjoyed a massive rise in both the quality and quantity of games on the market. What caused this? The online ad market boomed. It suddenly became (marginally) profitable to build a flash game, throw in some easily-included ads and set it free on the internet. A few well-documented hits made a relatively large amount of money, yet were often made by a single developer working in his spare time over the course of a few months (as previously flash simply couldn't fund an actual team of developers), and this caused a 'gold rush' effect of developers piling into the flash games space. Over time the ad model for flash games has matured into a market where developers can make money from various sources:

  • In-Game Ads: in-game ads such as MochiAds, usually shown once while the game is loading
  • Around-Game Ads: site ads like Google AdSense shown around the flash game either on the developer's own site, or on a site like Kongregate or Newgrounds which offers revenue share to developers
  • Sponsorship: this is where a portal pays the developer to 'tag' their game with the portal's branding (and usually a 'more games' link), effectively paying for traffic delivered to the portal as the game is distributed around the internet. FlashGameLicense was set up to help developers find sponsors for their games, and it has proven to be very effective.
  • Licensing: this is where a portal or site pays a developer for a one-off license to use their game; generally they pay a fixed fee to be able to use the game without the sponsor logo, in-game ads, links to the developer's site, etc on their own site; multiple licenses can be sold alongside a sponsorship

Generally speaking you can, and should, use all these options at once as Ada Chen advised in a talk she gave at Casual Connect in 2008. This model is working for some developers, the ones who can efficiently make engaging, short flash games and keep churning them out, but it's really only been a success for very few. Most flash game developers are still relying on other sources than ad-funded games to keep going full-time (for example, making games on contract for third parties).

Not Enough To Go Around

The problem with the ad model is that all the money is coming from one limited pool: advertising. You might find that sponsorship and licensing get you significantly more than in-game ads, but the money from those things comes from that same pool. Portals buy traffic from you (via sponsorship/licensing) with the money they earn from .. advertising! The amount of money in the advertising pool is limited, plus needs to be shared out amongst a whole load of middlemen before it trickles through to developers. No one has explained this better than Dan Cook in his recent Flash Love Letter, Part 1:

The guys making the big bucks here are the ones aggregating lots of games and leveraging massive visitor traffic (like the big games portals), or else delivering a solution used by all developers and getting an aggregated margin that way (like the ad companies). Individual developers simply cannot get the high levels of traffic necessary for ad-funded solutions to bring in the (serious) cash.

A Better Model

Luckily there's a better way to fund game development than scrounging for ad-pennies. It's been proven in almost every form of consumer entertainment ever made, from theatre to music to cinema and yes, even games: ask the consumer of the entertainment to pay you for providing it. That's it. Asking the players to fund game development takes away the dilution effect of trying to get ads to pay everyone's cut, and directly rewards the developer regardless of the size of their 'aggregated traffic-power'. It works for all those other kinds of entertainment, and it certainly works for the rest of the gaming industry.

And it can work for flash games too. Several developers have been successfully charging players for full versions of their free flash games, by integrating a payment processor such as PayPal. This method (often called a "demo", write that down) is so proven that almost no console or PC game doesn't use it. Others have tried splitting out the purchase into smaller bundles using a microtransaction/virtual currency provider, and are charging for decorative things like a fancy hat or small upgrades like level packs and new weapons instead of selling the whole game in one go. In fact recently launched providers such as MochiCoins, GamerSafe and Heyzap have made it easier than ever for flash developers to take payments from players. One advantage of the idea of using virtual items, temporary powerups, or other small purchases is that you aren't putting a cap on how much your biggest fans are able to spend on your game. Generally speaking selling virtual items works best in a persistant-world / MMO style of game, where you can put all kinds of social and economic effects into play to really leverage the idea - just look at this breakdown.

Regardless of how you are charging players, or what they are paying for, the fact that you are charging at all means you are using what I call the 'Premium Flash Game' revenue model.

Premium Games Need To Be Frickin' Sweet

One downside to charging money upfront is that you need to make players fall in love with your game before they will pull out the credit card, and that means spending a lot more time polishing the gameplay and expanding the content before release. The quality level of today's (and yesterday's!) flash games is definitely high enough to convince players to pay - developers just need to focus on expanding the experience; make "long form games" instead of focusing on quick, throw-away games. Again no one's explained this better than Dan Cook, so make sure to read his Flash Love Letter, Part 2 - you can do it right now if you like, we'll pause this part of the internet until you come back.

And Now For Some Examples

Lets have a look at some real-world examples of revenue made by flash developers using the Ad Model, and compare them to ones using the Premium Model. I'm going to use 'Gross eCPM', a term I just made up, as the baseline stat to compare these ad-based apples versus premium oranges. If you aren't familiar with it, eCPM is an advertiser's term and stands for effective cost-per-mille - or how much an advertiser has to pay out per 1,000 impressions of their ad on average. As the payee, you can think of it as how much revenue you made per thousand plays of your ad-enabled game. What I call Gross eCPM is calculated by taking the total amount of plays of a game, and dividing it by the total revenue made from them (whether it be from ads, sponsorship, microtransactions or full game purchases). This handily lets us compare two very different ways of monetising with a single comparative number.

First up let's look at the numbers for some flash games using the traditional Ad Model to generate revenue:

Desktop Tower Defense (play)
One of the original 'break out hits' of modern free flash games, created by a single developer, and supported by ads inside & around the game. 

Total Plays: 15 million in the first few months
Gross Revenue: ~$12,000 in that same time frame
Gross eCPM:

Mytheria (play)
A fairly typical successful flash game, though not a massive hit in terms of plays

Total Plays: 3.7 million plays to date
Gross Revenue:
~$8,200 to date
Gross eCPM: ~$2.22
[source: email interview]

Armor Wars (play)
Another game by the same developer as Mytheria (Diffusion Games), released afterwards to stronger interest from sponsors

Total Plays: 2.2 million plays to date
Gross Revenue: ~$9,300 to date
Gross eCPM:
[source: email interview]

Chronotron (play) Another game created by a single developer, and supported largely by revenue share on ads on Kongregate.

Total Plays: 7 million at time of this article
Gross Revenue: ~$15,000 in that same time frame
Gross eCPM:

Now let's have a look at some games using the Premium Model by selling full games:

Fantastic Contraption (play)
A free-to-play flash game, hosted on it's own site plus some portals, with a premium unlock for $10 that let you make your own levels and play other people's custom levels. Included solution-sharing via unique URL that helped it spread virally.

Total Plays: "over 3.5M unique users in the first 3 or so months"
Gross Revenue:
"for every unique site visitor, he converts 0.5% to a paid version [at $10]" = ~$175,000
Gross eCPM:

Now Boarding (play)
A free-to-play flash game hosted on various portals that had an upsell to a downloadable for-sale version (at ~$15)

Total Plays: 4.2M - 6.2M plays (some portals made it impossible to track this, hence the range) over the last year
Gross Revenue: 10,500 sales so far x $15 = ~$155,000
Gross eCPM:
~$25.00-36.90, depending on above
[source: phone interview]

And some games using the Premium Model by using microtransactions:

Twin Shot (play)
A free-to-play flash game by Nitrome with various virtual currency unlocks, including a level pack and cheats

Total Plays: "over 10 million plays"
Gross Revenue: unspecified (but calculations from the eCPM they gave says it would be about $25,000 at the time of the Q&A)
Gross eCPM:
~$2.50 but up to around $5.00 in english speaking territories (based on 60% developer cut of Mochi Coins revenue alone)

SAS: Zombie Assault 2 (play)
A free-to-play flash game by Ninja Kiwi with various virtual currency unlocks

Total Plays: "about 5.7M plays and 700k plays from the expansion pack" = 6.4M plays
Gross Revenue:
Gross eCPM:
~$3.50 but up to over $11.00 in english speaking territories (based on 60% developer cut of Mochi Coin revenue alone)

Minions On Ice (play)
A free-to-play multiplayer flash game by the Casual Collective where you could pay to get bonuses and access to extra vehicles quicker than normal

Total Plays: n/a
Gross Revenue: n/a
Gross eCPM:
an ARPU of $0.40 was mentioned by the developer, which means $0.40 revenue per unique player. My Gross eCPM counts total plays rather than unique plays, but if we ignore that we would get a Gross eCPM of $400; if we had the 'total plays' number this would be lower - but not all that much lower.

That's a massive, orders-of-magnitude difference between the revenue rate for ad-funded flash games and premium flash games. And once you start charging the players instead of hoping for ad money, the sky's the limit. Puzzle Pirates, a casual MMO run by Three Rings revealed last year that they make make an ARPU of ~$1.50 per player, per month - which would give a comparative Gross eCPM of ~$1,500. Yep.

Set Phasers To Premium

I hope this has convinced you, the flash game developer, to seriously consider moving away from the Ad Model and moving into Premium Flash Games. It's the future - embrace it.

PS- Many thanks to all the flash developers who have shared their revenue numbers with the rest of the industry. We too will be doing this as we work on our first game.

Wow, this is a really great read, Colm. I'm glad someone is talking about this, and your examples are very informative.

Kudos Glen! The actual revenue data is terrific. Wondering if any of these premium games uses the method of first X levels are free and final X are unlocked via payment.

I think the lack of a sense of ownership might be a deterrent here. A game of equivalent quality and cost on an iPhone gives the consumer a sense that they've actually obtained something (because it resides on a device they possess). But anything on the internet is inherently not "ownable" by the consumer since the product is not under their control (eg, the website goes down, forgotten login credentials etc).

Perhaps if the user could download the flash game and play it offline on their desktop as part of the purchase then this would become a more accepted model by consumers. (I understand this is possible already with some trickery, but it is not generally supported).

I'd be interested to hear if others think this isn't an issue and why.

To Ben Sullivan:

I would say it isn't an issue, because non-download content only affects ad-based/licensed income. There ARE flash games which allows user to download, though granted they're few and far between.

In fact, a suitable solution is to have both options present; Users can either play the ad-based/licensed game online, or purchase and download the offline version. Granted there's the whole issue with piracy, but that itself is mitigated simply by the fact that a free version exists anyway.

Thanks for the kind words.

Eric: Twin Shot 2 in my examples does just that; 50 levels for free and an 'evil themed' 50 level pack for sale. Nitrome said in the linked Q&A that they will try a different approach next time however.

Ben: A good point about ownership. The full version of Now Boarding is an installable game packaged up via Adobe AIR which runs on win/mac/linux. If you go to their site and install the demo you'll see how straightforward it is. Definitely a good approach as long as you are happy with the constraints involved (no high end GFX/3D, full screen but without resolution switching).

This article is what I'd been waiting to read for a long time!!! Straight to the numbers and full of useful links!

I have a 3d animated motion comic distributed for free at my website ( and tried the ad revenue model with no success, even when selling my own t-shirts and stuff. I'll be going for the Premium model for the next episode and see how it goes.

I've been creating some games as well but what worries me about Flash is the piracy issue. Anyone has links or info on how to avoid piracy on Flash games?
