Gringo Warrior


We will begin the second day of the conference with a Gringo Warrior lockpicking contest. However the number of participants will be limited so we will use the first come first served rule on the second day.

Gringo Warrior is a scenario-based lockpicking game. Set in a hypothetical kidnapping situation, participants are placed in custody of fictional captors who are holding them against their will and extorting money or some other ransom.

Instead of complying with their demands, participants use lockpicks, assorted tools, or even improvised items like paperclips and beer cans in order to affect their escape through a variety of impediments.

Starting out in handcuffs, players in Gringo Warrior have to free themselves from these shackles, then escape from the “room” in which they are being held… essentially, they simply have to open a locked doorknob. In this scenario, their captors have taken the player’s wallet/passport and have it locked in a filing cabinet. If the participant chooses, he or she may try to open this lock as well. There is one more door lock between them and freedom, but it is a deadbolt and slightly harder than the previous one. Ultimately, if the kidnap victim makes it outside the last door, they even have the option of attempting an automotive lock in order to make use of one of the captors’ vehicles as they escape to freedom.
