The casino games are in the hands of croupiers from Otumoetai Lions Club.
Treasurer Ann Treadgold says the casino night - this year is the fifth - is the toy library's major fundraiser.
This year it will be doubly important to raise plenty of money as the toy library has just come through a bit of a sticky patch.
Ann says there has been ''a bit of a blip'' in funding streams.
''In the short term, things were a little bleak,'' she says. ''We've been applying for grants and one [from COGS] has come through now and there are a couple of others that are usually reliable in the pipeline.''
After hearing of the toy library's plight, Rotorua MP Todd McClay made a donation of stationery and a basket of goodies.
''Over the years I've had the opportunity to visit the toy library and they do a fantastic job,'' he says.
''It's important for the wider community to be involved as it can be challenging for organisations like this.''
Ann says the running costs of the toy library sit around $35,000, with subscriptions, toy hireage and fundraising meeting around $15,000 of that.
The rest comes from grants.
She says she is looking at other revenue streams such as sponsorship from businesses.
