Getting Started
At the start of the game, you will need to insert coins to get credit. Press to gain 1,000 credits each time. When you are done, press to complete. Then use to bet, with 3 coins covering all possible combinations of rows.
 * First coin: Covers just the middle row.
 * Second coin: Covers both the upper and lower rows.
 * Final coin: Covers the diagonals.

Gameplay
When the slots have started spinning, you can choose to stop them at any point. They spin too fast to see what you will end up with, but it is some more interactivity and after all these slots can go on spinning for a very long time.

When the large red button is lit, the game changes slightly. The smaller red dots will come on one after the other until the red light sequence has ended. In this mode, you can bet on individual slot stops. Bet using and stop a reel. Individual columns pay out. If you wish to change your mind about the bet, hit a few times in a row. After the fourth small light, the mode will return to basic slot spinning.
