I guess there's no filter option for $0.30 tables yet. OnGame is not available for US players so the developers prossibly didn't realise there were 30c tables. Please create a ticket on the
Support system , and link to this thread.
Suggestion: I don't know whether the TableTracker architecture allows it, but it might be a good idea to allow us to choose a range of limits, rather than having to select specific limits (I mean, as well as, of course).
