What is SIMDEX™?

The handicap built for indoor golf.

Official golf handicaps don't accept simulator scores, and every simulator brand plays differently. SIMDEX™ is SimLeague HQ's indoor handicap standard: it gives every golfer one verified number that's fair across lounges, simulators and settings — so you can play in leagues and tournaments against anyone, anywhere.

How SIMDEX™ levels the field

A quick look at why indoor scores aren't comparable today, and how SIMDEX™ gives every golfer one fair, verified number — no matter which simulator or lounge they play.

One fair number

Every simulator plays a little differently. SIMDEX™ turns your scores from any brand of simulator into one comparable handicap.

Accounts for sim settings

Things like automatic putting circles make indoor golf easier than the course. SIMDEX™ adjusts for them so a 74 means the same everywhere.

Built to stop sandbagging

Your index uses your best recent rounds and verified scorecards, so players can't inflate it to win prize pools.

Your ticket to compete

A verified SIMDEX™ lets you enter local skins, state series and national events against players at any lounge.

How to get yours

  1. 1. Play at any participating lounge.
  2. 2. Scan your final scorecard with your phone.
  3. 3. Get verified after 8 rounds and unlock your Passport.

Governance Rules

EPV Gimmie Curve

Auto-gimmie radii differ by bay. SIMDEX™ applies an Expected Putting Value adjustment based on how often golfers actually make putts from that distance, so a generous gimmie no longer means a cheaper score.

Cross-Hardware Modifier

Each supported simulator platform carries a calibrated modifier maintained by SimLeague HQ. Modifiers are locked for sanctioned events and cannot be edited by venues or players.

Anti-Sandbagging

Your SIMDEX™ uses the best 4 of your last 8 verified rounds. Sudden upward moves are capped, and exceptional rounds are reviewed automatically.

Dispute Policy

Score disputes must be filed within 48 hours via your venue. HQ reviews the verified scorecard capture; decisions are final for sanctioned events.
