Graphics and Sounds

You can start with 10 up to 100 coins per bet. 4 of a King slot pays from left to right, right to left and through the middle. This 5-reel slot has 3 rows and 10 paylines. If you want to make the most of it, play Bitcoin slots with the max number of paylines. You can click the “spin” button yourself or set it to auto, letting the reels spin until you tell it to stop. If you want to increase your coin bet, click the coin at the upper left corner.

When you first start playing, you get different-colored card symbols and two dealer symbols. If you get a winning combo, the cards will flip over, revealing the kings. It doesn’t stop here though. When you win, you can choose to “take the win,” or “take a risk.”

Bonuses and Special Features

You’ll enjoy this slot’s payouts. Getting the top symbol payout will give you 5,000x your line bet for 5. If you get 5 dealer symbols, you can get 2,500x for 5.  In 4 of a King, the wild symbol is a poker chip with a 4 written on it. It will replace all the symbols and will give you more winning combos. It can even expand to adjacent reels.

This slot also has a “Risk” game. If you take the risk, you’ll see five facedown cards. You need to pick a card with a higher value than the computer’s face up card. Win and you can double your winnings.
