The Button Bars on Video Slot games vary considerably in appearance, but provide basically the same displays and controls, as described below:
Pay Table Button(s). Clicking on a Pay Table button allows you to view the Pay Table Screen, which shows you the rules, paylines, payouts and bonuses for the game you are playing.
Ticker Display. This is the display window at the top of the Button Bar. It displays information relevant to the game. The exact information given varies between games.
Coins Display. Not to be confused with the Coins Button, which may have a display built into it; the Coins Display is usually on the far left, and shows the number of coins that you have left to bet. Note that this will vary depending on the value of the coins you are using. If you have 1000 credits and are using 1-credit coins, the Coins Display will read 1000. If you are using 100-credit coins, the Coins Display will read 10.
Sometimes, the Coins display will not be labelled, and will only show the relevant figure.
Coin Selector. The Coin Selector looks slightly different on each game, but always shows a coin of the value that is currently selected for betting on this game. To change the value of the coins you are using, click on the Coin Selector until you have selected the coin of the value you want.
Note: Not all games have the same selection of coins; make sure you know how much you are betting before you spin!
Lines Button. The Lines Button allows you to change the number of paylines you bet on. Clicking it will increase the number of paylines in use by one, until the maximum is reached, after which it will return to one payline.
Coins Button. The Coins Button allows you to change the number of coins you are betting on each active payline, up to the maximum allowable for the game.
Gamble Button (Where applicable). Games that have a Gamble Feature will have a Gamble Button on their Button Bar. This button only becomes active immediately after a win on one or more of the paylines. If you win a payout, then before you spin again, you have the option to click the Gamble button, which lets you play a feature game in which you can gamble your winnings. If you win, you can keep gambling until either you lose, or you win the maximum gambling amount for that game. If you any of the gambles, you also lose your original payline win.
Auto Button. The Auto Button allows you to set up a number of automatic spins. When you click on it, a panel will pop up to enable you to enter the number of times you want the game to spin automatically for you. Once an automatic spin sequence has begun, you do not have to press anything else, as the game will continue placing bets and spinning automatically, until the number of auto-spins has been completed, while the display tells you how many automatic spins are left.
While Auto Spins are in progress, the button changes into a Stop button. Clicking the Stop button will end the Auto Spin sequence at the end of the current spin.
Bet Max Button. The Bet Max button is usually on the right, just next to the Spin button. Clicking the Bet Max button sets both the number of paylines and the number of coins per line to the maximum allowable for this game, and automatically spins the reels.
Note: the Bet Max button will not change the value of the coins you have selected, it will only bet the maximum number of coins possible on a single spin.
Spin Button. This button spins the reels, making a bet with the settings you have specified, as long as there is enough credit in your account to do so.
