During nine weeks, a riddle will be released every week. To enter the competition, you must answer a riddle correctly which will get you one entry into the raffle to win an Ipad Mini.
Each participant can play on all of the nine riddles, which corresponds to a maximum number of nine entries per participant into the raffle.
An incorrect answer will then disqualify the participant for the current riddle played, however it does not disqualify him/her to play on the subsequent 8 riddles.
If a participant answers to the same riddle on both Twitter and Linkedin, only one entry will be counted.
