WHAT YOU'LL NEED
You'll need a physical golf simulator setup running GSPRO software. GSPRO is the simulation platform the entire league plays on — all shot data, course play, and scoring runs through it.
An official launch monitor with a live connection to GSPRO is required. This ensures consistent, verified ball data across the entire field.
You'll need an active account on Simulator Golf Tour throughout the entire season. The SGT website also has full details on how to sign up and get started.
Your SGT COMBO handicap needs at least 20 rounds posted before the season begins. No cramming — don't try to post a bunch of rounds right before the season starts. The admin team monitors handicap activity.
All league communication — stream links, scheduling, results, and admin announcements — happens in the SGT Discord server. You'll need to be active there throughout the season.
Every round must be streamed live on YouTube, with the link submitted via that week's scorecard on mashupgolf.com before you tee off. If you haven't streamed before, Google's YouTube live streaming guide is a good place to start. See the streaming section below for the full league requirements.
HANDICAPPING
The league uses its own handicap, called MashCAP — the average of the best 40% of the rounds in your SGT Combo log. It fixes an imbalance in SGT's COMBO handicap: a player with 20 rounds counts their best 12 (60%), while a player with 48 rounds counts their best 16 (only 33%). MashCAP instead always counts roughly 40% of your total rounds, matching the USGA's standard. You can see your own MashCAP, and how it's calculated round by round, on the Handicaps page.
Each week, the field is also normalized so the best player in the field plays to scratch (0 handicap), with everyone else adjusting relative to them. This keeps the competition balanced regardless of skill level.
Handicap allowance varies by format — Solo Ringer plays at 85%, and team formats range from 70–80% depending on how many players' scores count toward the team total each hole, matching standard USGA guidance for that format type.
STREAMING REQUIREMENTS
Streaming is how we keep the league honest and accountable. Every player is required to go live on YouTube before their round starts and submit the link via that week's scorecard on mashupgolf.com. YouTube has a 24-hour wait period before a new account can go live, so sign up ahead of time if you don't already have one.
New to streaming? Check out this and this OBS tutorial, or set up a test stream and post it in Discord for feedback.
Rounds played without a stream are disqualified from that week's pot. If you forget to stream, you can replay with a stream running, but the worse of your two rounds counts. If a stream was properly attempted but had technical issues (frame drops, internet hiccups, etc.), the admin team decides case by case — that can mean a replay or the score standing as-is. Test your setup thoroughly, and consider monitoring your stream from a second device (phone or tablet) while you play.
