• The WSSA reserves the right to combine, split or eliminate certain age divisions in order to create more meaningful competition depending on the size and scope of each sanctioned tournament.
  • A Stacker’s Age Division coincides with their age on the final day of the tournament. (Note: The WSSA reserves the right to request proof of age for any Stacker.)
  • Tournaments: Separate “Male” and “Female” divisions are mandatory for age divisions 6U through 17-18 and optional for Collegiate, Masters and Seniors divisions depending on the size and scope of the tournament.
  • Doubles and Relay Teams – 6U to 18U compete in division of oldest stacker on team; 19+ to 60+ compete in division of youngest stacker on team. A stacker 18 years of age and younger may compete with a stacker 19 years of age and older in the “Open” division, which in tournaments is combined with the 19+ division.
  • Child/Parent Doubles – Division based on age of child. “Child” can be of any age and is limited to one team / Parent partner. A “Parent” is defined as a child’s parent, step-parent, legal guardian, grandparent or step-grandparent and may compete with each “child” in their immediate family.
  • Relay Teams may be made up of Stackers of multiple ages. (e.g., A Relay Team with Stackers of ages 7, 10, 11 and 12 will compete in the 12U division for the Relay events.) Stackers on Teams are limited to competing with only one Team throughout a single event.
  • Special Stackers Division – A Special Stacker is defined as a stacker that has a diagnosed physical and/or mental disability that would impede with the normal functioning necessary to perform a variety of sequential physical skills, specifically sport stacking.

Special Stackers competing in SS18 and younger divisions are students who require specially designed instruction and are served in a self contained classroom for 80-100% of their school day. Special Stackers competing in the SS19+ Division are adults who require assistance and/or support to access the workplace and employment. Special Stackers compete in one of two “levels” in their age division based on their average 3-6-3 time (except for Doubles and the Timed 3-6-3 Relay as noted). The average time for Level 1 is 7.999 seconds or below. The average time for Level 2 is 8.000 seconds or above. Special Stackers in the 15-18 Age Division may “play up” to the SS19+ Division for the Doubles and Timed 3-6-3 Relay events.
