RTP (Return to Player), the theoretical percentage of winning back the money put into a game over a very large number of games - it is a good indicator but provides little information about a specific game session. Volatility relates to the frequency and size of the payouts: a low-volatility game will provide more frequent payoffs of smaller amounts, and a high-volatility game will offer less frequent payoffs, but may have a larger potential payout. Both are important in choosing a game, as they will directly improve the session's experience, and both are much more significant than the theme of the game.
Popularity is a third factor, more practical – games that are more commonly played will likely have more helpful information, more consistent performance, and better track records, which will newer or niche titles simply not have developed yet. The rankings below come from the game library of OKBet, which takes into account all three factors, and not any one in isolation.
The No. 1 category by player volume on OKBet is Slots, and it's not hard to see why: they're fairly straightforward to play, and all you have to do is pick a bet size and hit spin. Check out all of our Jili games guide on the site, betting odds and bonus round analysis of the most popular slot titles.
As you compare slots, look at the RTP and the volatility rating (if available). Surprisingly, a slot with a high RTP but high volatility can have long runs of no real value to the player, who thinks that the RTP will reflect the rate of payout from one session to the next.
Table games are a different class of games: they're more structured, there's more room for informed decision-making, and in general, they offer lower house edges than most slots played with correct strategy. Basic strategy knowledge is rewarded in blackjack, baccarat involves no player decision other than the initial bet and roulette has a variety of bet types with a variety of odds.
This is because Baccarat is an easy game to play – it only offers 3 possible bets – and it offers a relatively small house edge on the banker bet in particular, making it a popular game in the Philippines.
A real dealer interpreting the game over a video live stream, sometimes with chat options to allow players to interact with each other, live dealer games fall at the intersection of the table game and social casino experience. These are usually more attractive to users that used to prefer the ambiance of brick-and-mortar casinos and wish to have a more comparable experience online.
In addition to the slots, table games, and live dealer options, slot machines also feature specialty games, such as bingo or scratch cards, which provide a less intense experience and are preferred by some gamers for shorter sessions. These are usually games of little or no strategy and can be learned and removed in a short amount of time and are often used for casual play.

Don't think of this as a list to work through so to speak, but as a list to start with, depending on what you are looking for in a particular session. For the fastest and easiest games to play, begin with the highest slots. For those who want to choose a game with a house edge that is not as high and clear rules, begin with table games. But when it comes to the social & real time aspect, then live dealer is worth considering even if it offers a slightly lower RTP than a slot.
The concept of volatility is clearer with an actual example. Let's take two slots, both of which have an RTP of 96%. Low-volatility: A player could win 40 smaller wins over 100 spins and not see a huge variation in the swings and losses or wins in a slot with low volatility. Slot B is high-volatility: You may only win 15 times in 100 spins; but a win may be a ten- or twenty-time payout and then a period of no wins occurs.
There is no "better" slot, they are just different for different tastes. A player seeking a more consistent experience with extended playing times with minimal dramatic swings would be better off playing Slot A. If you are willing to risk taking a long losing streak in order to have a big win in one shot, you may want to go with your slot of choice, which is called Slot B.
In addition to RTP and volatility, there are several other considerations to take into account when selecting a slot: the frequency and size of the bonus rounds, the highest possible win multiplier and how fun the base game is on its own even if you don't land a bonus round. A bonus round that is easy to trigger may make a slot with an interesting theme quickly boring, while a well-designed base game can still be fun even if you don't land on a bonus round.
It's also good to take a look at the lowest and highest betting limits of a slot machine because it will know how long the bankroll will last if you are betting on that range. Even with the same RTP, a slot that has a high minimum bet will use up a small budget much faster than a slot with flexible minimums.

Just because a new game has been released in the catalog doesn't mean it's one of the best, and it is a good idea to wait for a good amount of players to have been active and for the RTPs to have been published before assuming that it's one of the best titles. Buzz builds up around new releases sometimes because they have some really new mechanics, but a splash and a bang doesn't always mean the game will have legs.
One thing to do is to first test a new release in demo mode, get a proper idea of its pace and frequency of bonuses, and only then, either take it into your everyday real-money rotation with well-known releases or forget about it.
The argument can be made to play a limited number of games you know well, as this will make it easier to detect when a session is going as expected or not. Meanwhile, it's also a good idea to try something new every now and then so play doesn't become repetitive and to find a beloved game that was previously unknown. A sensible compromise is to reserve most of the money in each session for playing the same games and to use a small portion of the session's budget for a new game in each session.
Each slot has a paytable — a reference screen that displays the payouts of each symbol combination and details any bonus features. Before playing, it is best to see this before going into spins as it provides a much better idea of what you can expect from a specific title, what bonus rounds trigger and the approximate value of the highest payouts compared to the base bet.
In table games, it's knowing the actual payout percentages of the different types of bets that can be made before you make them — as there are some that are actually quite a bit worse than others, despite being roughly the same length on the game board, such as in roulette and baccarat.
While it may be obvious to only list the games with the highest jackpots, this doesn't necessarily mean the game will be of the highest quality or value. A large jackpot that seems to be statistically very unlikely to win doesn't tell you anything about how a game works during the vast majority of normal game sessions where the jackpot is not applied. When ranking games, we take into account more important factors such as realistic session experience, RTP, volatility, and bonus frequency than the headline jackpots, which are only relevant to those few who are in the jackpot mindset.

RTP is the acronym for Return to Player, which is the theoretical long-term payback rate of a game and is based on a very large number of rounds. It's a handy reference point, but doesn't indicate what may happen in any given session.
In general, yes with regards to long-run value, but there is volatility to consider as well. Although a high-RTP and high volatility game might be the best for getting the big wins, it can also have extended periods of losing streaks between huge victories, depending on the player's preference of smooth vs. swingy games.
Low volatility slots are more likely to offer smaller, more frequent payouts, resulting in a more stable gaming experience. Slots that have a high volatility have smaller payout frequencies but higher potential payouts, and therefore larger swings.
Play some of the various formats in brief sessions and take note of the payout limits, the dealer's style, and how fast or slow they are. The 'best' live dealer game will be the one that you feel most comfortable with, and that you enjoy the most.
