Fibonacci

The Fibonacci sequence is the series of numbers: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, ... The next number is found by adding up the two numbers before it.

1+1=2
1+2=3
2+3=5
5+8=13

Similarly to other games (1024 or 2048) the aim is to get to the 18th number in the sequence (4181) by merging tiles which are consecutive in the sequence.
