If you’ve heard about a ‘game’ named Roblox, then you’ve already been given the wrong end of the stick. Rather than a singular game, Roblox is a platform that hosts millions of games created by users themselves. Roblox is a global phenomenon that attracts people of all ages and walks of life. 

David Baszucki and Erik Cassel, founders of Roblox, believed in a block-based coding system to make game creation more accessible. Spoiler alert: it was a brilliant idea, leading to historical success, and games are not the only things users can create! An endless Roblox catalog is available to find cosmetic content shared by players.

What is Roblox?

Created in 2006, Roblox is an online platform where players create and play games. Developers at the Roblox Corporation wished to create a virtual universe where players could express their imagination through user-generated content.

Available in 16 languages, players around the world can meet virtually and socialize thanks to millions of games of all types on Roblox servers. Since 2024, the integration of simultaneous AI translation to in-game chat has allowed players to break the language barrier.

With most of its community being children and teenagers (56% of players are younger than 16 years old), Roblox does its best to keep players safe with monitoring systems and filters. The goal is to ensure that Roblox characters and content are appropriate for players of all ages.

What can you play Roblox on?

You can play Roblox on a wide range of different platforms. It initially came out on Windows PC. However, it’s now available on iOS devices, Android devices, PS4, and Xbox One, as well as some TVs. 

You can download Roblox for free and start discovering the games created by other players. One of the perks of Roblox is its cross-play functionality. That means people on different devices can all play together. It also means that you can swap from one device to another with the same account and keep your progress.

A free browser extension also exists to make the user experience more seamless. Roblox+ aims at notifying players when some exclusive items are available to buy or are on sale, better inventory management, and trade notifications. However, this extension does not allow players to access games directly.

Is Roblox free?

Yes. Downloading Roblox is free, as are many of its games. It’s also completely free to make your own games via the Roblox Studio. You can enjoy most of the Roblox experience without spending a single cent on the game.

When it comes to the best free Roblox games, we recommend:

• Brookhaven RP
• Adopt Me!
• Grow a Garden
• Piggy
• Bedwars

Some extra features can be accessed thanks to paid transactions, but all of the above games are perfectly functional for free.

A virtual in-game currency exists, called Robux. These can be spent in a whole host of different ways. For example, you can customize your Roblox avatar with exclusive cosmetics. Robux can also grant you access to unique games as well as the ability to enhance your experience with particular abilities or access to restricted areas in the virtual world. 

There are two ways you can buy Robux: with a one-time payment that will give you a definite amount of the virtual currency, or you can subscribe to Roblox Premium. Every month, you pay a fee and receive Robux alongside a few other perks.

Roblox Marketplace stands as another paid feature and allows you to create, share, and buy cosmetic items to customize your avatar. Some exclusive items, Limited and Limited U, respectively, can be resold by premium users only. Selling items on the marketplace is also a way to get Robux through transactions made within the platform.

What are Roblox game modes?

Every single game, or ‘experience’, is distinct. There’s no limit to the type of game developers can create, which means that your way to play will be completely different from one game to another. Experiences are divided into different modes. The most popular genres available include simulation games, horror experiences, RPGs, and platformers.

It’s hard to determine the exact number of experiences available on Roblox; people create and delete them all the time. However, in 2025 so far, there have been 6.4 million distinct games available to play.

How popular is Roblox in 2025?

On August 23, 2025, 47.4 million concurrent players were active at the same time, breaking the pre-existing record. Roblox initially gained traction in the 2010s and became even more popular as a result of the COVID-19 pandemic in 2020. In 2025, the platform records 79.5 million daily active users and 23.4 million unique paying users every month. In 2024, Roblox welcomed 340 million active users. 

Historically, Roblox has experienced constant user growth. While more than 9 million monthly active players were recorded in February 2016, it quickly moved up to 70 million in September 2018, 134 million in March 2020, and 300 million in May 2023.
