This topic is always a head scratcher to me. We had a regular weekly $2/4 limit game for several years played with 200 $1s and 300 $5s. Standard buyin was $60 with 10 whites and 10 reds.
Used to play with 10 people all the time and sometimes 16 at two tables. If we ever started running low I busted out $25s...but to be honest I don’t remember that happening often. Not once did I or any player ever think “hey, this game would run a lot better with 2-4x more chips.” And believe me, I’m a nut about things like that and would have bought more in a heart beat.
Now, years later, I joined this forum and found out that you “need”
at least 1000 chips to play 10 handed with 2000 being optimal. I think if you ask this question to poker chips enthusiasts vs just plain poker enthusiasts you may get a completely different answer. It’s like asking an alcoholic how much beer you should buy for a party.
