CBLOL is one of the oldest competitive leagues in League of Legends, on par with the South Korean LCK, but lower in status. The first competitions in South America were held in 2012 and since then the championships of the series have evolved.

As of 2022, the tournament has received its final look, which has become the hallmark of the competition.

CBLOL format

• 2 splits: CBLOL Split 1 (similar to Spring Split in other leagues), CBLOL Split 2 (similar to Summer Split in other leagues)
• 10 participating teams
• Double Round-robin (all teams play each other for 2 series)
• Bo1 match (all except playoffs)
• The best six teams go to the playoffs: TOP-4 get into the upper bracket, TOP-5 and TOP-6 get into the lower bracket

CBLOL Split 1 winners receive a direct ticket to the Mid-Season Invitational. CBLOL Split 2 champions advance to Worlds.

History of CBLOL: season 2012-2013

The first competitive tournament in South America hosted by Riot Games was the Riot Season 2 Brazilian Championship. The tournament was held towards the end of the second competitive season of the League of Legends as part of the Brasil Game Show.

Riot's first pen trial in a new region for the company was notable for its peculiar format, which will change radically in the future. Riot Season 2 Brazilian Championship featured only 8 teams.

All participants of the Riot Season 2 Brazilian Championship made it through the qualifiers and fought for $50,000. The games were played according to the Single Elimination system with bo3 matches. It is noteworthy that two members of the vTi organization met in the finals of the competition: Nox and Ignis. The last ones were the winners.

For the 2013 season, Riot improved the format a bit. Now the eight teams were divided into two equal groups, and only the 4 most successful teams according to the results of the group stage went to the playoffs. There were more matches and they had higher values. For the first time, the titular organization paiN Gaming entered the arena.

CBLOL 2014

The key change came in 2014. Then Riot held the first Brazilian regional tournament, from where the teams got to the International Wild Card Tournamenet.

After the IWCT, the winners of the mini-tournament had a chance to advance to the Worlds. From Brazil to Worlds 2014 went KaBum! e-sports.

CBLOL 2015

In 2015, the Brazilian league takes on the shape of a franchise. Teams from Promotion tournaments could still get into the basket of the best, however, the game within the Riot Brazilian Championship itself began to resemble the one that CBLOL will receive in the future: a single Double round-robin format, but with Bo2 matches.

6 teams go to the playoffs, and the playoffs themselves play in the single-elimination format. INTZ in the spring and paiN Gaming in the summer became the champions of the “trial” CBLOL.

CBLOL 2020 - transition to a franchise model

After structural changes at the dawn of CBLOL in 2012-2015, there were no significant changes until 2020. In 2020, CBLOL is finally moving to a franchise model. It happened on CBLOL Split 2.

CBLOL Split 2 was marked by a standard format for a single group with a Double-Elimination format and 8 participants. The main feature is that none of the teams left the championship following the results of the group stage.

The champions of the "real" CBLOL were INTZ, who dominated the league before.

In subsequent years, the teams did not leave the CBLOL league, but were listed as its partners. The only option to part with the slot was to buy it out by another organization.

In the 2021 and 2022 season, the number of teams increased to 10. For 2023, the list of CBLOL partner teams is as follows:

• Fluxo
• FURIA
• INTZ
• KaBuM! e-Sports
• Liberty
• Los Grandes
• LOUD
• paiN Gaming
• RED Canids
• Vivo Keyed Stars

Fluxo became newcomers to CBLOL Season 2023. The title Brazilians first announced an appearance in the League of Legends in December 2022.
