The Victorian government's battle with two gaming firms over huge compensation claims for the expiry of poker machine licences comes to a head on Thursday.

Tatts and Tabcorp lost their duopoly over the operation of poker machines outside of Melbourne's Crown casino in August 2012, following a state government decision four years earlier.

The government was in June ordered by the Supreme Court to pay Tatts $540 million in compensation, while Tabcorp's application for about $687 million was dismissed.

The government appealed the Tatts ruling, and a judgment will be handed down by the Victorian Court of Appeal at 1630 AEDT on Thursday.

However, Tabcorp also appealed its loss in the Supreme Court, and a judgment in that case will also be delivered at 1630 AEDT.
