Analysis
 What is theory /concept behind this game?
 How did I arrive at the number you guessed?
Binary numbers (1’s and 0’s) is the number system used by the
computer systems.
We humans use decimal number system that has 10 distinct
symbols (0,1,2,3,4,5,6,7,8,9)

Find the treasure game
 You have all been sent a message
 Collaborate among you to find a partner who
has the message that can decrypt the code
 Only one pair has the treasure location and the
rest have the password
 The pair that has the treasure location and the
pair that finds the password first together can
get the treasure and WIN.
