Croker isn't really a poker game, but more of a fruit machine game that uses poker-like combinations. You just keep dealing new cards and hold the ones you like.
The gameplay gets boring fairly quickly, and there's not much in the way of strategy involved.
The bonus game Bet Mania is essentially a clone of Bruce Forsyth's famous gameshow Play Your Cards Right, and is a nice novelty at first but with no real depth.
