Magic Camel

Android game "Magic Camel" involves camel asking the player to pick a random 2 digit number. In few steps the camel will find out your number. Do not believe? Try it now! The player is then asked to sum the digits of the number and subtract them from the original number. The Magic Camel then presents a list of symbols, of which the player finds the one corresponding to this new number. The dromedary (Magic Camel) then proceeds to correctly guess the player's symbol, supposedly after reading players mind.
