NFC - RFID Urban game using the touchatag contactless service

“ Capture the Tag” an NFC-based Urban Game powered by touchatag Antwerp, August 2009 By Derk Humblet & the touchatag team

Context: touchatag NFC urban game challenge in cooperation with Mobilkom A1

Capture the Tag an NFC-based Urban Game, powered by touchatag
Concept
Adapted from classic game “Capture the Flag” http://en.wikipedia.org/wiki/Capture_the_flag
Overview
Each of two teams, red & green, is assigned a “flag”—a set location marked by an NFC tag
Several additional ‘neutral node’ tags are located around designated play space
Goal: Locate and capture the other team’s tag before your own team’s tag is captured
But that is possible only after your team has captured enough neutral tags
Set up with game creator @derk_humblet, and referee @hansdemondt

Capture the Tag Setup
Participants
“ Team Green”
“ Team Red”
2 referees
Each team gets
One or more NFC phones
One map of the urban area (Antwerp, Belgium)
Starting Point
Referee gives a short briefing before game begins
Each teams starts from the location of their team’s tag
@bowa and Michael Elias at the briefing phase

Capture the Tag Game Play
All nodes are initially hidden
Players only know the location of their own team’s tag
Find and capture neutral nodes
Each node has a unique ID
Uses team’s NFC phone to claim a node
Claimed nodes can be reclaimed by other team
Winning
When a team claims enough neutral nodes, the location of other team’s flag is revealed
First team to scan the other team’s tag and correctly answer the question wins!
Having found a node, Bram Bogaert touches with his NFC phone

Capture the Tag Neutral Nodes
Nodes
Each is an NFC tag located at a fixed point somewhere in the city
To claim a node
Scan with NFC-phone
Phone prompts team with a question.
Correct answer captures node and possibly reveals clue hint to other hidden nodes
Incorrect answer reveals location of the node to opposing team (by text message), and forbids team from attempting to capture this node again for a set time period
Touching a NFC tag with an NFC phone @touchatag (Toon Coppens) attempts an answer

Capture the Tag Game Play Scenarios
When Team Red captures a neutral node…
Team Green gets text message that Red has captured a node
When Team Red claims a node that is already claimed by Team Green…
Team Green gets text message telling which node Team Red has claimed
When Team Red captures the flag…
Team Green gets text message telling them that Team Red has won the game
Hey, @touchatag and Diether: Only cheaters look up the answers online!

Result
We played with 8 people, 2 teams of 4 people
1 NFC phone per 2 people
The game lasted just over 1 hour
Great team building event as well (as far as this is needed in the touchatag team  )
