Slot 21 is another interesting game from Slotland provider, made exclusively for Win a Day casino players. Slot 21 game has Black Jack theme having 5 reels and 21 pay line, where the bet coin size starts from 0.01 cents, where the minimum bet is 0.21 cents. The symbols on this game are a bit classic having gold bars, cherries, red peppers, ringing bells, crowns, jester hats, lucky sevens and grapes. But watch out for the Ace, King, Queen and Jack symbols while you play, because collecting all 4 of them, will give you a special win of 2-200 X your bet.

But playing Slot 21 game,while you collect 4 of those symbols, the player needs to have higher balance then 1$, so that way you'll be given the opportunity to play the Black Jack game, pressing the 21 button, so that way, either will double your win or lose everything. Another bonus round is when scatter symbol lends on the fifth reel, you'll have a chance to play Red Black bonus game, so if the light color matches with the color of your card, which is on the right side of this game, the winnings will be doubled, but if not you lose everything, but you can bypass this bonus round and collect the winnings,without playing the bonus game.

I must say, when I played this game at the beginning I didn't understand it, but as I played it more often it's really interesting game, specially when it's given to be played for free. The only thing I didn't like about Slot 21 is its graphics and the colors which this game contains. I have played this game, many, many times and the last time I played was 2 days ago, as I mentioned before, even this game is given as a free tournament slot for any player can enjoy this game, even walk away as a winner of 50$ which Slotland gives you the opportunity in the free slotland site.

Good luck.

Slot 21 belongs of course also to the Slotland gaming platform and just like all the slots here that I had the opportunity to play before, is fundamentally different from the others. I guess that every game from Slotland would only bring exclamations of joy and superlative words, such beautiful and exciting are these slots.

If you are old enough, I guess that 30-40 years ago you had the chance to play at least once at the first slot machines that have paved the way to these online casinos. I mean the flippers of childhood (the pinball games) and the mechanical slots having 10-20 push buttons and as many flashing lights that lighted up randomly or not, and where you never knew what to expect. Playing Slot 21, I felt like being teleported back in time to the good old childhood in the „Luna Park“ (the largest park with mechanical games and slots from the Black Sea side, in the country where I am) waiting once again for some hundreds coins to fall at a lucky spin.

In a few words, even it is built like a classic slot, this slot is a true extravaganza, full of bright colors and flashing lights that shine and bring each a new element in the game.Like all slots from Slotland the number of paylines is unusual (21 paylines in this case) . To tell a little about the slot action, I will start saying that the basic symbols are the classic Cherries, the Seven, the Bell, the grapes etc. In addition to this, on the reel 5 (last reel) appear occasionally the 4 figures of the playing cards (A, K , Q, J) and a special symbol Red/Black which triggers the double up feature (so here you can not play when you want a Double Up - you need to wait for it to be offered). When a card game is visible on reel 5, it lights up the corresponding figure on the right up corner of the slot. When all the 4 figures lights are on, some random amount is added to a special „Bonus Game“- a BlackJack card game. The „Bonus game“ can only be triggered by the push on a button on demand, only when the total gain of a spin is over 1 Euro. The Double Up feature here is worth playing when the win is between 1 and 5 cents and can multiply up to 200x the original amount. There is of course present in this game also the Wild symbol and it is quite common . Telling about wins the slot is generous, and there are here some kind of progressive wins, the lowest being 1 cent and highest 10 Euro. It is quite common that once every 5-10 spins to have a win of at least 1 Euro, so the Bonus Round is triggered here without problems.

I repeat, the gaming experience is amazing, you have the impression that you are in front of a real mechanical slot machine from a few decades ago.
