Click the flag 2+ times so it actually works. Also I'm out of music so there is none. We go tetrational and quickly go past Giggol. Part 4 is from 10^^10 to 10^^10^^10. It is about 2:48 long.
Numbers come from many sources Part 6 will be coming soon and will be from 10^^^3 to 10^^^10. This is my 1,000th project!!
