Gambling

The first machine where Max tried his luck was the slot machine. 

Unlike earth where the slot machines were mostly digitally controlled, the dwarven made gambling machines were much more complex and mostly mechanically driven with the lucky jackpot being the triple hammer sequence instead of the cherries. 

The reason why Max chose to try his luck at the slot machine was because he had heard about the ' Rhythm Method ' in his past life which increased the odds of winning at a slot game. 

The way this method worked was that depending on how quickly one pulled at the start of each game, one could precisely control the outcome by stopping the reel each time at the same timeframe interval. 

With practice one could develop the skill of controlling the first reel to make it stop on the same symbol every time.

This way by being sure to catch the hammer in the first reel atleast, the chances to get a jackpot increased significantly.
