Pin Down is a game for Android that combines elements of capture the flag, a scavenger hunt, and geocaching.
In each 20 minute game, players compete in two teams to gather the most treasure while preventing their opponents from doing the same.
First, one player creates a game with a name and a codeword. The game is set to start in three minutes, during which other players can join based on the name and codeword and discuss strategies with their teammates.
Once the game begins, Team A has 3 minutes to place treasure and traps for the other team to find. Each player on Team A places 3 treasures (each worth one point) and 1 trap by walking to the location they want to place it and tapping the appropriate button. Treasures that are not placed after the 3 minutes is up are automatically awarded to Team B.
Next, Team B has 6 minutes to find as many of Team A's treasures as possible while avoiding their traps. To help Team B in their search, their screen will display the distance and approximate direction to the nearest treasure. If a player walks into a trap, their scanner is disabled for 30 seconds.
After a two minute break, the process repeats, this time with Team B hiding items and Team A searching for them.
Whichever team has the most points after both teams have had an opportunity to search wins.
The app is written in Android with a simple backend in PHP. Individual clients are more-or-less indifferent to who else is connected (as game rules such as even teams can typically be enforced by the players themselves), so Pin Down easily supports the drop-in, drop-out style play that is often necessary for games with large groups.
