The first thing to remember is that you have to have a stable internet connection. If you do, the next step is qualifying to enter the competition. Leo the ray will let you know when it starts, at which point you’ll have to collect just five bolts by beating levels. That will get you access to the tournament.
Keep collecting bolts to move up the Leaderboard and finish at the top. Once the competition is over, the top ten players will get prizes.
