Both the casino and nudge/hold machines feature the same basic controls. The top three buttons control the betting and spinning of the reels, se the left/right keys to select a button and press fire to activate that button. The basic buttons are:

Spin - Red button:
Simply spins the reels using the number of coins you have set.

Bet One - Yellow button:
Allows you to change the number of coins you bet. The maximum is three coins, the coins will cycle back to one if you press the button again.

Bet Max - Green button:
This button bets three coins and spins the reels automatically.

When the reels have spun the payout will be displayed if you have been lucky enough to win.

Nudge/Hold Machine:
The nudge/hold machine also features a number of additional buttons. Once the reels have been spun you may get the chance to hold or nudge any of the reels. Use the direction keys to select the appropriate button and press fire to activate it.

Hold: This holds the specified reel so that it is maintained on the next spin. These can be un-held by activating the button again before spinning the reels.

Nudge: Activating this button causes the specified reel to nudge to the next symbol (the one above the current symbol). Once nudged the reel cannot reset.

The number of nudges and holds are shown next to the appropriate buttons on the machine. If any reels are held on one spin you will not recieve any further holds for that spin.
