Motorbike repair minigame
From Summertime Saga Wiki
Grace - the motorbike not the character - is broken and the player is going to have it repair in a minigame all the easiest. This unique event is a mandatory step on Eve's route and 5 points in intelligence are a prerequisite to trigger it.
Instructions
Click on the wrench in the middle of the screen and start a circular movement in a clockwise direction. Continue until the counter at the bottom left shows 20 crank turns.
Reward
Fixing the bike allows the player to progress in Eve’s route.
