Fun Factor

Fun Factor is a relaxing but increasingly tricky number puzzle. It was developed partly as an experiment to discover how high a number can be reached mathematically. Give it a try and share your score in the comments!

Place numbers onto the board and connect them through their factors. Each number automatically links to any of its factors that already exist on the board.

The challenge is to keep the network untangled.

If lines start to cross, you’ll need to rearrange the board to keep the structure clean and playable.

The numbers keep increasing, the web grows more complex, and eventually the puzzle becomes surprisingly difficult to manage.

Simple rules. A satisfying mathematical web. How far can you go?

How to Play

• Place the next number onto the board. • It connects automatically to any numbers that are factors of it. • Avoid creating intersecting lines. • If things get messy, you can drag numbers to reorganize the web. • Keep the board untangled as long as possible.
