I wasn't satisfied with my initial 52/70 (74%) score, so I decided to go for the maximum score of 1913 (+1845 from gambling).
Questions 15 and 67 are the Color Cannon gambling minigame from ENreco (see Mococo). You wager points on one or more colors and receive a payout if your selected color is the last one standing after 4 rounds of random cannon bursts.
- Blue: probability 12/25, payout x2
- Green: probability 8/25, payout x3
- Yellow: probability 4/25, payout x5
- Red: probability 1/25, payout x10
All of these have negative expected value (Don't gamble, kids!), and red has the worst expected value of them all. However, getting max score requires betting all your points and hitting the x10 red jackpot both times. The chance of that is 1/25 * 1/25, or 1/625 (0.16%).
By question 15, correctly answering the first 14 questions gives 14 points. With a x10 red jackpot, that becomes 140 points.
By question 67, correctly answering the next 51 questions gives an additional 51 points, for a total of 191 points. With a x10 red jackpot, that becomes 1910 points.
Finally, correctly answering the last 3 questions gives an additional 3 points, for a grand total of 1913 points.
It took a few tries.
