Play Slot 21 for Free

Slot 21 sticks to some basic, old-school graphics and recreates a fun and addictive casino environment for players to enjoy.

The entire game screen is a close-up on a virtual slot machine set on a black background. The machine has a fun, lopsided look and features plenty of command buttons all over to help you customize your next spin freely.

Add some vintage sound effects and a lot of flashing lights, and there you have Slot 21. The game does not exactly have an original look given how popular retro slot game are nowadays, but at that point you are still probably curious about the gameplay itself. Let’s take a look at it in our next section.

Now that you are a bit more familiar with your surroundings, you will notice that Slot 21 actually follows a classic gameplay pattern with which you are probably already familiar.

You have 5 reels and 21 paylines to bet on at most, and your task consists of lining up symbol combinations onto these paylines in order to score some cash rewards. Use the command buttons at the bottom of the game screen to adjust your wager and the number of activated paylines before you let the reels spin loose.

Your rewards are determined by the symbols and the size of your wager. This means that betting more on the reels can lead to larger payouts in the future. If you are feeling lucky, set up the game the way you want and switch to autospin mode. This will let the reels spin on their own with a constant bet for as long as you want.

The paytable of Slot 21 features common reel symbols that you have probably seen in other slot games in the past.

The most frequent on the reels are the cherries, grapes, sevens and chili peppers. The rewards are capped to 100 times your wager with these symbols, which is already significant.

For even bigger wins, aim for the bells, gold and crown symbol. With winnings going up to x1000 here, needless to say that the stakes are exceptionally high. On top of all this, Slot 21 also includes some special features worth mentioning here.

The 3 different special features of Slot 21 help spice things up a little for the players, starting with the jester’s hat symbol. This wild card does not pay any cash prize but can instead replace any basic symbol listed above and give you an extra chance at a big win.

The red and black symbol is a scatter that can only appear on reel 5. Once you find one of them, you get a chance to wager your last win and double it by guessing the color of a hidden card. You can keep on playing as long as you win, but remember that a wrong guess will take all your money away.

Finally, remember to collect the Jack, Queen, King and Ace special symbols as you play. Once you have gathered all 4 of them, you gain access to the blackjack mini game. Follow the on-screen instructions and try to get as close to 21 with the cards you are dealt for a surprise jackpot prize.

Slot 21 is a classic slot game mixed with an original blackjack bonus feature that is both refreshing and unoriginal at the same time. This might sound paradoxical, but the game does appear to lack the charm and dynamism of other WinADay creations.

That being said, if you are all about classic casino games, then you will probably enjoy playing 2 of them at the same time and winning some sizable prizes in the process.
