The best single line slot is Emerald Diamond.
Emerald Diamond is a classic one-line slot online machine that plays and feels like a real physical slot machine in a Vegas casino. Red Tiger really nailed the visual design of this game.
The gameplay is very simple, as you would expect from a slot like this. The Emerald Diamond symbol is the only special feature, and it is a wild, a re-spin and a multiplier all baked into one.

Triple Tigers brings you a Chinese-themed online slot that focuses on one thing and one thing only. This is as simple as an online slot can get, which is what makes it good.
Pragmatic Play released Triple Tigers in 2018. The game became fairly popular with UK players who were looking for a straightforward online slot that was easy to play.
The game has no special features and only a single payline. Even though our experts love a complex slot, sometimes it's fun to go back to basics and enjoy the simpler things.

Halloween Luck has a very unique design, as it is a single line, single reel online slot. It also features a clever push-your-luck mechanic that lets you take more risks if that is what you want.
The game has three symbol columns, and each time you get a symbol, that column goes up by one. You can then claim everything you have collected so far or keep playing. The risk is that there is the pumpkin symbol that will reset them all.
There are also a few special symbols on the reels. The witch is a wild that lights up every column, and then there's the potion that will give you free spins with no chance of hitting the pumpkin.

NetEnt's Grand Spinn Superpot brings you a stylish slot machine that is played using only a single payline. The visual design reminds us of the classy European casinos, which is a nice change of pace from the Vegas-styled games.
The game has an interesting nudge feature. This activates after you win something and not when you almost win. The game will start going through the reels, and if the same symbol is above it, it will nudge it down for a new win. This can happen quite a few times for each win.
There are two versions of the Grand Spinn slot, the regular version and the Superpot slot. The difference between them is that the Superpot jackpot is a progressive jackpot, and the regular game has a fixed 10,000x Mega Jackpot.

Free Reelin Joker 1000 is an expanding single line slot that feels like you are spinning a combination lock.
The gameplay is very simple but unique. The reels have numbers on them, and the number you see when they stop is how many coins you win. If you get a 5 and a 0, those make a 50, which is your payout.
What makes the game even wilder is the special features. Occasionally, the reels squeeze a little, and if you hit a joker, you reveal a fourth digit. This can unlock the maximum win, 1,000 coins.

Multiplier Riches is an art-deco-themed online slot that would fit even Jay Gatsby's fancy estate.
The slot combines Vegas-style mechanics with an elaborate and extravagant visual design. The game looks beautiful and plays like a charm. The game is very similar to Emerald Riches, but Multiplier Riches changes the payout structure a bit. This makes it more volatile but, in our expert's eyes, a bit more lacklustre.
What makes Multiplier Riches special is the growing multiplier feature. Every multiplier that lands on the reels is added to the total multiplier, just waiting for the next winning combination.

What could be more British than a cricket-themed slot machine? Games Global's Cricket Penny Roller is just that, a single line online slot with a heavy focus on cricket.
Cricket Penny Roller is a penny slot, meaning that you can bet one penny per spin if you want to play at the lowest pay level. There are three levels, and playing at the maximum level gives a bit better payouts.
The game is very simple to play. There are no special features, and you see all the payouts immediately on the game's main screen. However, it is just that simplicity what draws players in.

Tree of Riches is Pragmatic Play's Chinese-themed single payline slot that has been surprisingly popular with UK players and casino experts.
The game looks very simple, but there are quite a lot of neat little special features hidden in there. With only a limited number of symbols, this is quite an achievement.
The wilds are what you want to see. They will substitute other symbols and sometimes add a random multiplier that can be up to 10x. And if you get two of them on a payline, the slot is re-spun as many times as it takes to get a win.

Grand Wheel is a slot with a seemingly simple design, but the Bonus Wheel mechanic is what turns this low-volatility slot into a thrilling game.
The base game is fairly simple. You have six symbols and one payline, and all the possible payouts are listed on the machine itself. Nothing that special just yet.
When you get a Grand Wheel symbol on any of the reels, you get a random multiplier payout. If you get two, those multipliers are first added together and then paid. And if you do happen to get all three Grand Wheels, you get a huge wager multiplier that can be up to 1,000 times your bet.

DJ Fox is our last highlighted game, and it is a bit of a stretch. This game starts off as a single line slot, but can temporarily become bigger.
Push Gaming's DJ Fox is a stylish game with a clever idea. When you hit VIP symbols, your playfield starts to grow. Your single payline turns into two, then three, then four and all the way up to five lines.
All this is done with re-spins with multipliers, so the payouts can grow quite rapidly.

Single line slot games are online slot machines with exactly one payline. The number of symbol reels can vary, but the common feature of these games is that only a single line can have a winning combination.
Single payline slots are often thematically classic slots, meaning they use symbols and visuals that were common in older physical slot machines.
There has been an increased popularity of single line slots lately, especially with Asian-themed games.
Single pay line slot machines often have a very limited number of special features. These games are more reminiscent of classic slots rather than modern online video slots.
There are some simpler features that are common with single pay line slots. These are bonus mechanics that you could have easily seen in physical slot machines.
Common features of single line slots include:
The number of paylines changes how a slot plays and feels. While it is mainly a personal preference, the number of lines can have some significance.
When you play multiline slots, you often see games with tons of special features and massive wins thanks to symbols hitting multiple lines. Single line slots, on the other hand, are simpler in design and compact.
While it is true that multiline games can have higher maximum payouts, the value of a single win relative to your bet is often better in single line slots.
Below, you can see some of the differences between single line and multi line slots:
| Single Line | Multi Line |
|---|---|
| Smaller payouts with single payline | Large total wins through multiple lines |
| Easy to evaluate symbols and wins | Symbol value can get confusing |
| Simpler gameplay | More bonus features |
