Choices at the table

How the decisions in Old Hazard, Full Steam, High Flush and Iron Duel work, and what our suggestions mean.

Four stalls with a choice

Four of our stalls ask you to choose something. In Full Steam you choose whether to throw the freight again. In High Flush you fold or raise. In Old Hazard you name a main before the first throw. In Iron Duel you call a rail, a colour or the inverse before the deal.

Only the first two change what a round is worth on average, so for those we show the option with the best long-run return on screen when the choice appears. The main in Old Hazard and the call in Iron Duel change how a round plays out, not much what it returns: seven nicks most often but also has its own outs, and the four calls in Iron Duel are within a whisker of each other.

How the suggestions are worked out

For Full Steam we work out, for the freight in front of you and the throws you have left, every way the next throws could land, and compare that with standing. High Flush uses a fixed rule found by simulating millions of hands: raise with four cards of a suit or more, or three headed by a jack or better.

The suggestions run in your browser with the same rules as the game, so they always match the pay plate.

What they do not do

Following a suggestion gives the best average over many rounds. It does not make any single round a winner, and it does not make the stall return more than it takes. Over a long run, even perfect play ends a little down.

That is exactly how games of chance work everywhere. Playing or success in these games does not imply future success at real-money gambling: no system or skill turns a game with a house edge into a way to come out ahead.
