International Platinum StarLeague Winter 2025 - CSLPRO Reimagined
CSLPROs Future - International Platinum StarLeague
The CSLPRO season has now ended with the finals at CSLAN 3. We want to start by thanking everyone for watching and playing in CSLPRO, without you guys none of this would be possible.
We’ve learned a lot and gotten lots of feedback on how we can make CSLPRO bigger and better. We’ve taken all of it to heart and we’re implementing a bunch of changes for the 2025/2026 season.
For all information about IPSL check out the IPSL page!
New Name - New Format - Same Passion
The first and most noticeable change we are enacting is rebranding CSLPRO to International Platinum StarLeague, IPSL for short.
International Platinum StarLeague will begin in September 2025 and run until August 2026. During those months there’ll be 2 starleagues, IPSL Winter 2025 and IPSL Spring 2026, 10 monthly tournaments and an offline finals at CSLAN 4. Yes, we will be back in Chicago for CSLAN 4 next August.
To accompany the changes in format there’s also some prize pool changes. IPSL Winter 2025 and IPSL Spring 2026 will have a prize pool of $1500 each. With prize money given to everyone who qualify and the Round of 16 and up. The monthlies will continue being $75 and have the same prize distribution as before. CSLAN 4 will have a prize pool of $2500. The prize pool distribution for CSLAN 4 will be announced closer to the event.
The Round of 4 players from each Starleague as well as the best performing player from the IPSL Monthlies will be invited with travel assistance to come to CSLAN 4 in Chicago to play in the Finals. Just like with the CSLPRO Finals anyone attending the LAN can participate.
International Platinum StarLeague Winter 2025

Starleague Format and Prize Pool Breakdown
The Starleagues have a similar format to ASL, so if you’re familiar with ASL’s format then you already have a good idea of how IPSL will work. Each Starleague consists of the Qualifiers to get into the IPSL starleagues and then the Main Tournament. The Main Tournament starts with the Round of 24.
Qualifiers
The Qualifiers consist of 3 Qualifier Days. Every player are divided into 4 groups for each Qualifier Day. 2 players qualify from each group so 8 players qualify per day. The winner of each group win $15 and the runner up $5.
Every group consists of a single bracket where every match is a Best of 3. There’s no lower brackets. If you don’t qualify during a Qualifier Day then you can play in the next one to try to qualify.
If you qualify for IPSL then you are not allowed to compete in the rest of the Qualifier Days. The players seeded into the Round of 16 are not allowed to play in any of the Qualifier Days.

Main Tournament
The main tournament consists of a Round of 24, Round of 16, Round of 8, Round of 4, Third place match, and the Grand Finals. The
Round of 24 consists of Best of 1s in a dual tournament format/”ASL format” in groups of 4 players with 2 players continuing on to the Round of 16 per group. There’s no additional prize money for losing in the Round of 24.
Round of 16 is also a dual tournament format/”ASL format”. The starting games are Best of 1s and Winners, Losers and Decider matches are Best of 3s. Every Round of 16 group consists of 4 players with 2 players per group winning their way to the Round of 8. Players who end their ISPL run in the Round of 16 win $40.
The Round of 8 consists of 4 sets of Best of 5s between 2 players. The winner of each Best of 5 continue to the Round of 4. The players who end their IPSL run in the Round of 8 win $80.
