However, keep in mind that penny slots can cost more than a cent, since there is a fixed number of paylines on some slots. For example, if you play on slots such as Vikings Go To Hell, the number of paylines is fixed at 25, and you can only adjust the coin value. This means that a $0.01 bet will now cost $0.25 per spin . Decide how much money you’re willing to bet and set yourself daily, weekly, or monthly limits.
