# A Carnival Puzzle
Suppose a carnival has games \(A_{1},A_{2}\), and exactly one must be played.
Game \(A_{i}\) has:
1. A four-sided die with \(F_{i}\in\{1,2,3,4\}\) good faces.
2. A starter score \(S_{i}\in\{0,1,2,3,4\}\).
Playing game \(A_{i}\) requires one to:
1. Roll its die exactly four times.
2. Exit the carnival with score \(\max(S,S_{i})+S_{3-i}\), where \(S\) is the
number of rolls that landed on good faces.
When should one play either game?
