Factor Dance

Prime factors · 30 levels

Dots dance into rings of rings: every number's portrait.

How to play

1. Tap a prime ring to add it inside your stack: every dot splits into that many dots. Tap a ring in the stack to take it out.
2. The first ring is the outside: 2 then 3 is two groups of 3; 3 then 2 is three pairs. Same number, different portrait!
3. Copy the target portrait, build the given number, or name the number in a portrait (multiply the group sizes).

Read a portrait from the outside in: how many big groups? Inside one, how many smaller groups? Keep going down to single dots.
