Every living room in the world seems to have different rules for the Box Game. One of the founding directives of the IBGL was to codify these variations with the goal of creating distinct divisions in which participants may compete. There are 5 formats of the game, each with their own restrictions.


In this format, competitors are free to adopt any technique to achieve the clutch and elevation, so long as the core rules are adhered to:

  • Competitors must be begin their attempt in a fully upright standing position
  • No other bodily part should make contact with the floor, nor any other supporting surface, other than feet or footwear.
  • Competitors must pick up the box with their mouth or teeth, elevating the box at least 30cm from the floor for a minimum of 2 seconds, all the while holding the box with their mouth or teeth only
  • If all of these criteria are fulfilled, the attempt is deemed to be successful


  • A foul is committed if any part of the competitor other than feet or footwear comes in contact with the ground or any other surface for support.
  • Loose clothing that is providing no supporting function may come in contact with the ground. It is important that competitors try to avoid this, and ensure that the clothing does not prevent adjudicators from determining whether the rules are being adhered to.
  • If the competitor makes a foul they are required to start again from a full standing starting position before recommencing their attempt
  • If three fouls have been committed at an attempt at a single height, the competitor may make no more attempts, and is removed from competition

nb. Because of the unrestrictive nature of the freestyle format of the game, remotely-submitted attempts for records are ineligible for inclusion due the difficulties with verifying below-zero heights. Records for this format will only be contested at events with an approved competition step setup


In this format, competitors are required to keep their legs straight at the knee from the standing position until the clutch and elevation has been completed, including when positioning their legs for the attempt. In this format, special attention needs to be paid to what part of the feet are on the ground. One of the following criteria must be satisfied:

  • The sole of one foot must have full contact with the floor. Full contact is defined as the ball of the foot and at least four toes. The competitor may use any part of the other foot below the ankle for support, including the side or top of the foot or toes.
  • OR, the soles of both feet must be in contact with the ground, with both having the ball and at least 2 toes touching the ground


In this format,  the competitor must clasp their hand together in front of them or behind their back. The arms may be bent or straight, but the hands must be held in the same position throughout the attempt. No restriction on the use of legs or the parts of the feet in contact with the floor applies, so long as the freestyle rules are applied-to.


In this format, the competitor must use only one foot for support:

  • The free leg must be lifted from the ground at the full standing position. It may be lifted freely or held, and the competitor is free to change the position and restraint of the free leg at any stage so long as it stays elevated and not in contact with any supporting surface.
  • The leg must remain off the ground until the attempt has been completed after the clutch and elevation


In the Crane format, the rules of Straight-leg and Hand-clasp are combined, so competitors must keep their legs straight as well as their hands clasped during the attempt.
