Tees: Choose the course handicap used for the entire season (Blue or Grey). Blue players may declare from Blue or Grey tees but always use the Blue course handicap. Grey players declare from Grey.
Audit: Play a declared round with another 18×18 competitor. Canyon Cup and Club Championship individual rounds are the exception.
Declaration: Declare before your tee shot on hole 1. You receive 50% of your course handicap that day.
Putting: The hole you take must be one you holed out on—no three-foot gimmies.
Posting: Post the result in WhatsApp and on canyon18x18.com after the declared round.
Lightning: If the horn sounds, wait to see if play resumes. If it does not, either undeclare or use a hole completed before the horn.
Fine print: You cannot declare, drive directly to only the remaining holes, play them, and post a score.
