This classic slot comes with an RTP of 95% and a medium volatility rate.

In the 5-Line Bonus 21 slot, the RTP (Return to Player) is below the average at 95%. This indicates that players can expect to receive 95% of their wagers back over an extended period of gameplay. The RTP serves as an indicator of the game's payout potential.

Medium volatility slots provide a mix of excitement and consistent gameplay, offering a moderate level of risk and reward.


5-Line Bonus 21

The 5-Line Bonus 21 slot is a traditional game that showcases recognizable symbols. Its design, however, appears somewhat dated. The playing grid consists of 3 reels and 3 rows, set against a dark brown backdrop. Above each reel, there are collectors for Bonus symbols. At the top of the screen, there is a mini reel that becomes active during the Blackjack bonus minigame, along with the game's logo featuring the charming Lady Joker. The Lady Joker also acts as the Wild symbol in this game. While there is no soundtrack, players can enjoy authentic slot machine sounds during gameplay.

On the reels, players will find familiar symbols such as cherries, lemons, oranges, plums, bells, grapes, watermelons, and Lucky 7s. Forming a winning combination of 3 identical symbols can reward players with payouts ranging from 2x to 25x their bet. Additionally, the Wild symbol has the power to substitute for any regular symbol and offers a payout of 200x the stake when 3 Wild symbols align on a payline.

Finally, collecting 3 special Bonus 21 symbols will trigger the bonus minigame.

Bonus Rounds & Free Spins

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.

Overall Rating


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.
