Hint Unlocking Museum bonuses
To unlock most of the pictures in the Museum, just start each of the three main games five or ten times. Then, play each one for a few hours. Just leave the game idling. You do not have to be actually playing for that amount of time. Play Sonic Gems Collection once every day and accumulate over 24 hours of game play. Then, start the game 30 to 70 times to unlock the different end Bosses to many classic Sonic games that you can play.
