All registered players and coaches must be current members of USA Lacrosse.

Registration is open to any player, or team of players, under the age of 18 and members of USA Lacrosse. Players may form their own teams solely for the purpose of the playday, but must plan to have an adult present and on the team side-line to serve as a coach on the day of the playday. Players may also register as individuals and will be placed on a team with other individual registrants at the selected division level.

Teams and players may play up a division, but they may not play down a division or age group.

All high school, U14 and U12 games are anticipated as full field games. All U10 and U8 games will be half field.

There will be one central horn used for all timing.

Timing: games are currently projected to have four 10 minute quarters, 2 minute quarter breaks,5 minute half time, running clock, and 5 minutes between games. Timing may change depending on the number of Registrants.

The ATX 2026 Zebra Open Girls' Lacrosse Playday will follow all USA Lacrosse and NFHS Rules as it pertains to each age level with some specific modifications, to be determined based on final timing and registration numbers. Full playday rules will be posted here and emailed to Registrants by October 5, 2026.
