joining 99 Slots — A Complete Guide to Choosing the Right Game
How slots work, which type of game suits you best, and what to understand before you play — all in one guide.
Slot Types and Their Differences
Not all slots are the same. Slots can be divided into several main categories based on their mechanics, number of paylines, and bonus structure.
Classic Slots
3 reels, simple paylines, and old-school symbols like cherries and sevens. Ideal if you want to play in a familiar format. Fiery Sevens or Hot Triple Sevens are popular examples of this type.
Video Slots
5 or more reels, many paylines, and rich animations. They feature free spins, multipliers, and special bonus rounds. Fortune Tiger and Gates of Olympus are games of this type.
Megaways Slots
The height of each reel changes on every spin, so the number of possible winning paths can reach from thousands to hundreds of thousands. Bonanza Megaways and Extra Chilli Megaways are pioneers of this technology.
Jackpot Slots
Fixed or progressive — a set prize or a pool that grows with every bet. Super Ace and Fortune Gems 2 are well-known names in this type of slot.
How to Choose the Right Slot for You
Keep three things in mind — volatility, theme, and budget — and choosing a slot becomes much easier.
What Is Volatility and Why Does It Matter?
Volatility refers to how often and how much a slot pays. High volatility games deliver large wins, but less frequently. Low volatility games pay smaller amounts more often. Mahjong Ways 2 is a good example of high volatility, while Fortune Mouse is known for relatively steady payouts.
Match the Theme to Your Mood
A slot's theme shapes the overall experience. If you enjoy mythology, Gates of Olympus or Rise of Apollo are good options. If you prefer fruits and colorful symbols, Sweet Bonanza or Sugar Rush will be enjoyable. For Eastern motifs, try Fortune Tiger or Mahjong Ways.
Set Your Bet According to Your Budget
Every slot has a minimum and maximum bet range. If you want to play for a long time on a small budget, choose a low volatility game and keep your bet size low. Check the RTP — the higher the maximum RTP, the better the theoretical return. Fortune Mouse has a maximum RTP of 96.96%, and Mahjong Ways 2 has 96.95% — games with high RTP offer an added advantage for longer sessions.
RTP Comparison of Popular Slots
The list below shows the maximum RTP of several slots available at joining 99. RTP is a theoretical return rate — it is a long-term average, not a guarantee for every session.

RTP is a theoretical rate — a long-term statistic, not a guaranteed return in every session.
Practical Tips for Playing Slots
A few tips drawn from experience that are useful for players at every level.
Start in Demo Mode
Before putting real money into a new slot, try it in demo mode first to understand the bonus features and patterns. This gives you a feel for the game's pace and frequency.
Set a Session Budget
Decide how much you will spend in a session before you start. Increasing your bet to chase losses is a harmful habit — avoid it.
Read the Bonus Feature Rules
Every slot's free spins, multipliers, or bonus buy has its own rules. Looking at the paytable once will show you which symbols are worth the most.
Manage Your Bet According to Volatility
High volatility games can have larger drawdowns. Set your bet size in line with your bankroll so that you have a chance of reaching the bonus rounds.
Choose Games by RTP
If you want to play for a longer time in a long session, choose games with a higher RTP. Keep in mind that RTP is a long-term average — anything can happen in a single session.
Play Responsibly
Slots are for entertainment. Treating them as entertainment rather than a source of income makes decisions easier. For more information, read the responsible gaming guide.

Common Misconceptions About Slots
Many players hold some mistaken beliefs about slots that are not true in practice.
"If I haven't won in a long time, I'm more likely to win now"
Every spin in a slot is controlled by a Random Number Generator (RNG). Previous results have no connection to the next spin. Each spin is an independent event.
"Increasing my bet raises my chances of winning"
If you win with a larger bet, the payout is larger too, but the probability of winning does not change. RTP and volatility are not affected by bet size.
"Slots pay more at certain times of day"
Slots do not pay more or less at specific times of day. The RNG operates at the same rate around the clock — there is no difference between morning and night.
"After a jackpot is hit, the game goes cold"
After a jackpot is hit, the game's RTP and spin mechanics remain exactly the same. A game does not go cold or hot — the result of every spin is determined independently.
"Betting max increases your chances of winning"
It is true that on some slots, all features unlock at max bet. However, this does not increase the probability of winning — it only activates certain bonus rounds.
"Playing longer guarantees a win"
RTP is a long-term average — it is calculated over millions of spins. Any outcome is possible in a single session. Spending more time does not guarantee winning more.
