How to play Factor Links

Tap tiles to build a chain using each once. For every neighboring pair, one number must divide the other with no remainder. Tap a selected tile to remove it. Any valid full chain wins.

Choose Daily challenge for today’s shared set, or a practice level for a fresh set. Daily difficulty increases over five rounds. You may retry an incorrect answer; each incorrect check reduces that round’s score by 10. Hints cost 15. Reveal gives the worked solution for 0 points. Reloading resumes your daily round.
