Ookina, better known as Leonardo Mantovani, is a huge TFT and slot streamer from Brazil who’s managed to create a great community around himself. Having blown up in the TFT and gambling space over the last several years, he’s not going anywhere anytime soon.

His methodical TFT playstyle, combined with his fun and entertaining personality, has put him in an interesting spot. His viewers are less focused on his content and more on him as a person.
With over 415,000 followers on Twitch and growing, he may not be the biggest or richest streamer in the world, but he’s done pretty well for himself.

Ookina’s Net Worth & Revenue Streams
While Ookina may not be among the absolute top-earning streamers on Twitch, he still has more money sitting around than the vast majority of people. With dedication to his craft, he’s managed to build a substantial nest egg.
Based on available data regarding his Twitch earnings and sponsorships, we estimate his net worth to be approaching, but still just under, $500,000 USD.
Primary Income Sources
- Twitch Income: The vast majority of OOkina’s wealth has come directly from Twitch ads and sponsorships. With between 600-1200 viewers per stream, a couple of 3-4 minute ads an hour will really add up, at least 5 figures per month.
- YouTube Income: While less than his Twitch income, the ads shown on his YouTube videos likely earn him a pretty penny each month, as he hasn’t struggled with monetization issues.
- Sponsorships: Ookina has had several sponsorships over the years, including several lucrative casino deals. Through these sponsorships, he’s likely made over $100,000.
Streaming Journey & Background of Ookina
Ookina, one of the larger TFT and online casino streamers in Brazil, has managed to carve a decent niche out for himself on Twitch. Born on February 15, 1995, in Guarujá do Sul, his journey to streaming stardom started off slow. With some dedication, he’s created one of the more loyal fan bases you’ll find on the platform.
Early in life, he wasn’t too big of a gamer; instead, he focused on dancing until he turned 26, finding that his true calling lay in the world of streaming. His success was largely based on the growth of TFT, but his fun personality definitely didn’t hurt.
Roughly 8 years ago, he decided to start streaming and managed to grab a decent number of Twitch followers in just a couple of months, hitting 1,000 within 7 months of starting. Once he managed to hit that 1000 number, his growth exploded, as he was able to really connect with his audience and showcase some high-level TFT gameplay that wasn’t too common in Brazil.

It didn’t take much longer to become a Twitch Partner, solidifying himself in the scene. However, it wasn’t just TFT that drove his popularity; he also played League of Legends and the old MMORPG Tibia, managing to hold his viewership across multiple games.
He also started streaming online slots in late 2023, but that side of his content has remained a smaller portion compared to his regular online gaming streams.
In recent years, he’s grown his YouTube channel alongside his Twitch following, bringing him a lot more money and reach.
His partner has also been a big part of his success, playing puppetmaster behind the scenes and helping him focus on what matters: his content. Instead of messing around with collabs and losing mental space, his partner deals with all of that.
