rules:
each post contains either a number or a word (ping or pong)
its a normal count 1, 2, 3, 4, etc
every time the number is a multiple of 5 you write ping instead of the number and game goes back to previous user.
every time the number is a multiple of 7 you write pong instead of the number and game goes back to previous user.
number like 35 or 70 u write Ping-Pong and game flows normally (no previous user)
for exemple the person that writes the number 3 cant write the word ping as game didnt go back, this avoids a little bit of post number padding.
so exemple:
User A: 1
User B: 2
User C: 3
User A: 4
User D: ping
User A: 6
User C: pong
User A: 8
every time someone errors (wrong number/number instead of word/previous user not the replier of a word/post edited(this will count as an error:P))
Update on post edit rule: a post 1 min after previous aka double post can be edited. as it just happened on first 6. this should allow game to continue after a double post.
if the previous user doesnt reply in 24 hour time another can reply (to avoid topic dying)
Best try: 35
