Math Bowling

Game Rules

1. On a player's turn, a math problem must be answered to initiate a bowling roll.
2. A player must answer math problems until filling a frame just like bowling.
3. Players must fill all 10 frames just like bowling to finish the game.
4. A player has 15 seconds to answer an addition/subtraction problem and 30 seconds to answer a multiplication/division problem.
5. If a player does not answer on time, whatever was entered is taken as the answer. If nothing was entered, then the answer is assumed to be 0.
6. If an answer is correct, the player gets the equivalent of knocking all remaining pins (a strike for 10, a spare for less than 10).
7. If an answer is within the number of remaining pins from the correct answer, then it is considered close. The player gets the equivalent of knocked pins for that answer (e.g. answering 3 or 5 to 2 + 2 gets all remaining pins minus 1). This makes answering the next math problem more challenging just like how the second roll is often more challenging in bowling.
8. If an answer is farther from the correct answer than number of remaining pins, then 0 is awarded.
9. Players with the highest score at the end win.
10. If all players have the same score at the end, it is a tie.
11. Players are distinguished by number.
12. The game may be played with one player only, in which case it is always that player's turn on every bowling roll (problem answer).
