StructureAsian Open Sport Stacking Championships


Prelims Code "open_3829" should be written and placed in view of the camera Stackers will have until 10:00 pm on December 4th (SG Time) to upload pre-recorded videos. Be sure to give yourself plenty of time to upload your videos, late entries will be disqualified.

  • Individual Prelims:

    In this video, the stacker must do their prelims just like they would at an in-person tournament by doing two warm ups and three attempts for each of the three individual events (3-3-3, 3-6-3, Cycle). Everything must be recorded together with no breaks, just like at an in-person tournament.
    Sample Video Submission
  • Child/Parent Doubles Cycle (SS 3-6-3) Prelims:

    Stackers submit a video of two warms and three Cycle (SS 3-6-3) attempts. This event will work like traditional C/P Doubles where one stacker is the right hand and the other is the left hand.
    Sample Video Submission
  • Online Doubles Cycle (SS 3-6-3) Prelims:

    Stackers submit a video of two warms and three Cycle (SS 3-6-3) attempts. The times for each attempt will be averaged with the times their Doubles partner submits and that will be the time for the Doubles team.
    Sample Video Submission
  • Online Timed 3-6-3 Relay:

    Stackers submit a video of three 3-6-3 attempts (no warm ups). The time for each attempt will be added to the times their relay teammates submit and the sum of each attempt will be the times for the team. Teams may have 4, 5 or 6 members, but only times for the fastest 4 members will be used to calculate the team's time. If any of the fastest 4 times is a scratch that whole attempt will be a scratch, we do not move on to stacker 5 or 6.
    Sample Video Submission

Prelims will be judged offline and the results posted on the WSSA website.

Video Instructions:

  • Camera must be in front of the stacker. Videos taken from the side will result in a scratch. Try to light the stacker from the front and avoid strong backlighting
  • Stackers must abide by all WSSA rules, including the rule requiring that: “All cups used at WSSA events must have original Speed Stacks printing that is clearly visible and in good condition. This rule applies to all cups in a set.
  • Event code must be visible to the camera and in the room with the stacker, no video overlays or editing in the code are allowed. Attempts without an event code will be a scratch
  • Camera view does not need to include the stackers head but must include all cups , both side to side and vertically. If using a TD, it must also be completely within the camera view.

    Each video must be filmed without breaks and the stacker must remain in view between attempts.
  • Stackers without a TD must clearly show a zero to the camera before each attempt and must clearly show their final time to the camera after each attempt. Attempts without showing a zero to start and the final time at the end will be a scratch.
