Playing Chess Online
Playing chess online should be fun. Here are the most common questions about playing SparkChess on our website and about chess in general.
Why does the board look wrong, images are missing?
SparkChess should look and work perfectly on any browser released in the last 5 years. We test it thoroughly and make sure there are no issues on Chrome and Chromium-based browsers (Microsoft Edge, Opera, etc.) as well as on Firefox.
There are isolated reports of the board not displaying correctly and in some rare cases missing images. The known conditions are:
- older Microsoft Edge with high contrast mode enabled;
- Chrome (or another Chrome-based browser) with a Dark Mode extension.
Extensions can affect your browsing experience in unexpected ways. If you have extensions enabled, try loading SparkChess in an incognito (or private) window, without extensions. It should run fine. You can also try disabling one extension at a time to see which one is misbehaving.
What are the browser requirements for playing SparkChess online?
SparkChess works on any modern browser. Supported browsers include:
- Microsoft Edge Browser
- Google Chrome and Chrome for Android
- Safari and iOS Safari
- Opera, Vivaldi, etc.
- Android Browser
We strive to keep SparkChess compatible to as many browsers as possible, but there’s always a tradeoff. As of 2020, SparkChess still works on Internet Explorer 10+, but it’s no longer officially supported.
If in doubt, we recommend you to use Google Chrome (or its open source brother Chromium) on any platform as it provides all the features SparkChess needs, speed, stability and security.
For Internet Explorer 9 and below we still have a Flash-based version but it’s no longer updated and supported.
Why do you show ads?
SparkChess could not exist without ads and paying customers. Simply put, they pay the bills.
Developing a game like SparkChess, operating a website with over two million monthly views and maintaining a multiplayer service that needs to be up and responsive 24/7 is not cheap.
For example, we use MaxCDN so that the game loads as fast as possible, we use a EV SSL certificate to make sure the connection is secure, DNS with failover so the site never goes down, IP filtering to mitigate attacks, code signing certificates so you can trust downloading the game and so on. We even need to buy mobile phones and tablets to make sure SparkChess runs anywhere. Then there’s development and customer support.
For ads, we’ve been using AdSense exclusively. AdSense has the most strict rules for websites and advertisers and disallow misleading ads, malware or annoying ad types. They don’t pay best, but we feel they are the best for you, the player. We also try not to abuse ads – on any given page you will not find more than 2 ads, even though most sites place far more than that.
We are now experimenting with in-game ads for two main reasons: it’s what Google recommends for games and they allow the game to take up all the screen size. We think it’s a good tradeoff. Currently we show ads when the game starts and then on game over, at least 8 minutes apart.
Is playing SparkChess online free?
Yes. Online play is free, although we display unobtrusive ads from Google. If you prefer not seeing ads, you can download the standalone version of the game or subscribe to SparkChess Premium Live.
I see both SparkChess and flashCHESS mentioned. What’s the difference between them?
They are the same product. When we created the first game engine in 2002, we called it flashCHESS. Later, in 2008 the third generation of the engine, rewritten from scratch, took the web by storm and we wanted to keep the name due to its heritage, naming it flashCHESS III. Later, to prevent any trademark complaints from Adobe regarding the use of “Flash”, we decided to rename the game as SparkChess.
