what was the player count of roblox in 2018

In 2018, Roblox had roughly 70 million monthly active users (often reported as “around 70 million” or “nearly 70 million”) and was already one of the largest online gaming platforms by user base.

What “player count” means for Roblox

Roblox doesn’t usually talk about a single “player count” number like a traditional game. Instead, it uses several metrics:

• Monthly Active Users (MAU) – how many unique accounts played at least once in a month.
• Daily Active Users (DAU) – how many unique accounts played on a given day.
• Hours Engaged – total time spent in the platform.
• Concurrent users – how many people are online at the same moment (less commonly highlighted in old press).

When people ask “player count of Roblox in 2018,” they’re usually asking for the MAU figure, because that’s the one most press releases and articles used back then.

Roblox’s 2018 user numbers

By 2018, Roblox had already grown significantly from its early 2000s roots:

• In 2017 , Roblox reported about 58 million monthly active users.

• In 2018 , multiple sources and summaries of Roblox’s growth say the platform reached around 70 million monthly active users. Some reports phrase it as “nearly 70 million” or “more than 70 million” depending on the exact month.
• Roblox also noted over 100 million registered accounts by 2018, but many of those were inactive or old accounts, so the active user count (the true “player count”) is the 70m MAU figure.

There is no single official “December 2018” number publicly broken down by month in most summaries, but the 2018 range is consistently described as ~70 million MAU.

Daily and concurrent users in 2018

While MAU is the headline number, it’s useful to understand what that implies:

• If roughly 70 million users played at least once in a month, a typical daily active user count would be in the tens of millions (often 20–30m+ on popular days), depending on seasonality (school holidays, weekends, etc.).
• Concurrent users (people online at the same time) in 2018 were likely in the several millions at peak times, but Roblox didn’t widely publish precise 2018 concurrent numbers in the same way it does later metrics.

Over time, Roblox’s numbers exploded:

• 2020: over 100 million MAU
• 2024: ~79.5 million MAU (note: some reporting shows fluctuation due to different definitions and measurement periods)
• 2025–2026: hundreds of millions of total users and record concurrent peaks over 40–47 million.

Quick summary

• 2018 Roblox “player count” : ~70 million monthly active users.
• Registered accounts : >100 million , but many inactive.
• The most meaningful and commonly cited figure for “how many players” in 2018 is the ~70 million MAU number.
