prometric Slots – The story behind the reels, strategy, and a complete guide to choosing the best slots
From classic fruit machines to Megaways slots with thousands of paylines – each has its own character. This guide explains how to choose the right slot, what volatility means, and which mistakes new players commonly make.
How the types of slots differ
From classic to jackpot – each category works differently
Classic Slots
Typically 3 reels and a limited number of paylines. Simple mechanics built around fruit symbols, BAR, and sevens. A good starting point for new players.
Simple mechanics 3 reelsVideo Slots
Modern 5-reel slots with themed animations, free spins, bonus rounds, and various special features. Gates of Olympus and Sweet Bonanza are well-known examples of this type.
Bonus rounds ThemesMegaways Slots
Big Time Gaming's licensed engine. The height of each reel changes on every spin, resulting in up to thousands of ways to win. Bonanza Megaways and Extra Chilli Megaways are popular names in this format.
Variable reels High volatilityJackpot Slots
Progressive or fixed jackpot mechanic. A small portion of each bet goes into the prize pool, and one lucky player wins the big reward. Higher risk, higher potential reward.
Progressive Big rewards
Why Megaways mechanics are different
In a standard 5-reel slot, paylines are fixed. In a Megaways slot, each reel can be between 2 and 7 symbols tall, so the number of ways to win in a single spin can reach anywhere from 500 to 117,649.
Because of this high volatility, you may go many spins without a win, but a strong spin can land a large multiplier. The Tumble feature in Bonanza Megaways makes this experience even more engaging.

Which slot is right for you
How to balance volatility, RTP, and your budget
The biggest mistake when choosing a slot is betting based on theme or graphics alone. Understanding three key factors makes the decision much easier:
Volatility
Low volatility slots offer frequent wins, but the amounts are small. High volatility slots may go a long time without a win, but a large win can come suddenly. If your balance is low, it is wise to start with low or mid volatility slots.
Understanding RTP
RTP (Return to Player) is a game's theoretical return rate, expressed as an average across millions of spins over the long term. Fortune Mouse has a maximum RTP of 96.96%, Gates of Olympus has a maximum RTP of 96.50%, and Bonanza Megaways has a maximum RTP of 96%. This figure is not a guarantee for each spin, but a higher RTP means a comparatively lower house edge over time.
Budget planning
Decide before a session how much you are willing to spend. A common rule is to keep each bet no more than 1%–2% of your total budget. This gives you enough spins on high volatility slots to trigger bonus rounds.
| Game | Studio | Max RTP |
|---|---|---|
| Fortune Mouse | PG Soft | 96.96% |
| Mahjong Ways 2 | PG Soft | 96.95% |
| Mahjong Ways | PG Soft | 96.92% |
| Fortune Tiger | PG Soft | 96.81% |
| Extra Chilli Megaways | Big Time Gaming | 96.82% |
| Gates of Olympus | Pragmatic Play | 96.50% |
| Super Ace | JILI | 97% |
| Aviator | Spribe | 97% |
RTP is a theoretical figure and does not guarantee the outcome of any individual session.
Themes and studio profiles
What kind of experience each studio's games offer
Eastern-themed slots – dragons, pandas, mahjong – are especially popular among Bangladeshi players. PG Soft's Fortune Tiger, Fortune Mouse, and Mahjong Ways series are the most played in this market. JILI's Super Ace and Fortune Gems, on the other hand, give the feel of classic card games.
Pragmatic Play's Gates of Olympus and Sweet Bonanza are built around Greek mythology and candy themes – their bright colours and straightforward mechanics have made them familiar to players of all ages.
Hacksaw Gaming's games are more cinematic – the animations and soundtracks in Le Bandit or Wanted Dead or a Wild feel much like watching a film.

Practical tips for playing slots
What experienced players keep in mind
Set a budget first
Decide at the start of a session the maximum you will spend. When you reach that limit, stop playing – whether you are ahead or behind.
Try demo mode first
Before putting real money into a new slot, use demo mode to understand how often the bonus triggers and how the mechanics work.
Start with small bets
Spend some time on a new slot at the minimum bet. Once you understand the mechanics, increase your bet according to your budget.
Take breaks
Long continuous sessions reduce focus and affect decision-making. Take regular breaks.
Read the pay table
Every slot has a pay table that explains symbol values, the conditions for triggering bonuses, and special features.
Focus on one type of slot
Switching between 5 or 6 different slots in the same session means you never get a chance to understand the mechanics of any of them. Stick to two or three slots you like.
Common misconceptions about slots and the facts
Popular myths worth examining
"A 'hot' slot machine pays out more"
Every spin is controlled by an RNG (Random Number Generator), so the result of a previous spin has no effect on the next one. The idea of a "hot" or "cold" machine is completely false.
"Increasing your bet raises the chance of a bonus"
A bonus round triggers at a fixed probability on each spin, with no connection to bet size. A larger bet does, however, increase the amount won.
"After a big jackpot, it won't pay again"
Even on jackpot slots, every spin is independent. After a previous jackpot, the very next spin has the same probability of triggering one.
"Higher RTP means a lower house edge over the long term"
Correct. A 97% RTP means that theoretically, an average of ৳97 comes back for every ৳100 bet. However, this is the average across billions of spins – within a single session the ratio can be entirely different.
"Playing responsibly can make slots a source of entertainment"
Setting a budget, keeping to a time limit, and not treating results as a source of income – these three habits can turn slots into a controlled form of entertainment. Read the responsible gaming guidelines to learn more.
New experiences beyond slots
Outside classic slot mechanics, prediction-based games are gradually gaining popularity. Monster Plinko is one such game where a ball travels down a path and the multiplier is determined by where it lands. There are no reels as in slots, but it offers the same kind of fast-paced entertainment. For full details on this game, visit the Monster Plinko guide.
