Isolated and stranded in the middle of the ocean, Tom participates in a trivia quiz to try to win a prestigious trophy, the Golden Brain.
You need to answer 555 multiple-choice questions on various themes.
If your answer is correct, you move on to the next question.
If your answer is wrong, you fall into the water.
There is a checkpoint for each question.
The green counter displays your score.
The red counter shows how many times you have fallen into the water.
A timer records your time. Hurry up!
Players who complete the game earn the Golden Brain trophy.
Aim for a high score, fast time, and few falls into the water.
Your progress is saved automatically at regular intervals.
I’ve put a lot of effort into finding the right balance (hello, I’m Scratch), making sure the questions aren't too easy or too difficult.
My goal was to make the challenge fun and fair for everyone.
I hope you enjoy the game. Good luck!
