The objective is to slide the numbered tiles on the grid and combine them to obtain higher numbers.

In this variation of the game you have to combine the tiles in correspondence with the Fibonacci sequence, i.e. 1, 1, 2, 3, 5 ...

Swipe or use the arrow keys to move the tiles. Go back up to 5 moves by tapping on the small arrow key at the top or by pressing "B".
