Use
Once The Pig placed a Reverse Bear Trap on a Survivor's head, the Game will randomly choose one of the available  as the key to remove said Reverse Bear Trap, with the others serving as decoys.

Trapped Survivors will see the of all available  that they have not yet searched.

Searching a Jigsaw Box for the key to unlock the Reverse Bear Trap will take ' to complete and has a chance of ' to trigger each second. Failing these Skill Checks will briefly pause (for ') the Progression, apply a Regression penalty of ', and trigger a Loud Noise notification for The Pig, alerting her to the Player's location.

Once the progress bar is full, either of two things will happen depending on whether or not it was the correct Jigsaw Box:

Correct Jigsaw Box

 * The Reverse Bear Trap is removed from the Survivor's head.

Wrong Jigsaw Box

 * The  of that Jigsaw Box is no longer shown to the Survivor.

Patch 2.5.0

Trivia

 * In the Game files ' are also being referred to under the name Puzzle Box'.
 * The presence of  on a Map reveal The Pig's identity to Survivors in a similar fashion as do The Trapper's Bear Traps.

10 Pints of Sacrifice Trap

 * The ' are most likely inspired by the 10 Pints of Sacrifice Trap featured in SAW V. They have a similar look and some of the Add-ons affecting the ' point to a similar use.
 * This Trap required the Victims to "donate" 10 Pints of their own blood within 15 minutes, to unlock a door or they would be killed by nail bombs located in the room. Inside the Trap, circular blades would cut open the Victims' hands and collect the blood in a glass beaker below.
