What is the relationship between the number of paylines and the cost to play a slot game?

The number of 7️⃣ paylines available in a game is one of the most important features of a slot machine. If a game has 7️⃣ 40 lines and one credit per line, then the base bet is 40 credits. However, if you place a dollar 7️⃣ bet on a five-line slot at 20 cents per payline, the payout is higher.
