• Not all multiple coin machines provide you with the option of betting in ranges.
• Some of them provide you with the option to choose the number of coins you wish to bet, there is a bet max option in most machines.
• Read the pay lines properly in multi-reel, multi-pay line machines. Do not mess up there. Refer the chart for the payoffs and the bonus spins applicable for select combinations of images.
• Understand the wildcard images provided there in the payoff list if any.
