About this quiz
Each Fibonacci number is the sum of the two before it: 1, 1, 2, 3, 5, 8. Only a handful fall below 100, so most of the board is mined.
- There are 10 different Fibonacci numbers from 1 to 100.
- The last one on the board is 89; the next, 144, is off it.
- 1 appears twice in the sequence but once on the board.
