Bonus 21 Feature

On the rightmost reel, some symbols land with an overlayed Bonus 21 symbol that is collected at the end of a spin to the Bonus panel. When all 3 Bonus 21 panels are highlighted, the Bonus 21 feature will start.

In this bonus game, you draw cards displayed on the mini-reel in the upper part of the playing screen by pressing the start button. Every card has a value in points almost like in Blackjack starting with 2 and going up to 11. The points on the card drawn will be added to the meter below the mini-reel. Cards will be drawn until the point total of 21 or higher. Point totals between 17 and 21 represent a win according to the table next to the card reel. In the case the point total is between 17 and 21, the player can either collect a win or draw another card. If the point total is 21, the corresponding win will be collected automatically. But if the point total exceeds 21, the feature will end without a win.

While playing 5-Line Bonus 21, players have the opportunity to win payouts of up to 200x their bet. It's important to note that the winning potential in this classic slot game is relatively modest. To achieve the maximum possible win, players must aim to land a winning combination of 3+ Wild symbols on the reels. This combination holds the key to securing the highest payout available in the game.

5-Line Bonus 21 by Eurocoin Interactive offers a classic 3x3 slot machine experience with familiar symbols. The visual presentation is somewhat generic, lacking modern aesthetics. The inclusion of a Blackjack-like mini-game is the sole bonus feature that adds excitement and liveliness to the base game. However, the low winning potential and below-average RTP might deter even the most dedicated fans of classic slots. While it can provide some entertainment, players seeking higher payouts and better return rates may find other options more appealing.
