On the older three-reel slots, the advice was to always bet the maximum number of coins allowed because that was the only way you could qualify for the jackpot. Most new video slot machines don’t adhere to this rule. Most video slot machines pay proportionally to the number of coins you bet and there is no bonus for betting the maximum.
This is when you need to study the machine you are playing. Never just start playing a slot machine. Always make sure you understand the payouts, the bonuses, and the requirements for the jackpot. If the jackpot does not require you to play the maximum number of coins, then don’t. I will explain why in the last strategy.
