What's New

Gone Free! Enjoy the challenge of building Nacci numbers into the millions! Also, check out Fibonacci Central, our new feature that brings all the best stuff about Fibonacci together in a single entertaining library.

App Description

1, 1, 2, 3, 5, 8, 13, 21... And on and on. It's the Fibonacci sequence, where every new number is the sum of the previous two. In Nacci, your job is to join up the Fibonaccis together, one by one. That's right, find the two ones on the board first and join them into a 2. Then find another one and join it to the 2 to become a 3. Then find another two and and join it to the 3 to become a 5. If you can't find the number you need, you can make it by joining numbers together on the board. See how far you can go before you run out of options.
