Casino game studios are the creators of slots and table games for a big number of online casinos. However, would you be aware that the very same game may have different bonus features at various casinos? Such a situation can be extremely bewildering for the players. They could be playing a game at one casino where they like it very much and then at a different site, they find it completely different. To get familiar with the reasons that happen and the ways of solving this problem is the prime objective of this article.
Why Game Studios Change Their Bonus Features
Casino game studios like NetEnt, Microgaming and Playtech make games for many casinos, like Rainbet Canada. They sometimes change how bonuses work based on where the game is played. This is not random. There are real reasons for these changes.
The main reasons include:
- Casino requests for custom versions
- Different gambling laws in various countries
- Market testing of new features
- Casino-specific promotional deals
A recent study by Gaming Analytics Group found that 42% of major slot titles have at least some variation in bonus mechanics across different platforms. This is a big number that affects many players.
Regional Regulation Differences
One big reason for changes is laws. Different countries have different rules about gambling. In some places, certain bonus features are not allowed. For example, in the UK, auto-play features have been banned. So game studios must make UK versions without this feature.
In Sweden, there are strict limits on bonus amounts. This means games there might have smaller potential wins. The same game in Malta might offer much bigger jackpots.
Popular Studios Known for Inconsistent Mechanics

Some game studios are known for changing their games more than others. Let’s look at the main ones:
| Studio Name | Consistency Rating (1-10) | Common Variations | Affected Game Types |
| NetEnt | 5 | RTP percentages, bonus frequency | Slots, table games |
| Playtech | 4 | Jackpot mechanics, free spins terms | Slots, live dealer games |
| Pragmatic Play | 6 | Volatility settings, max win caps | Mainly slot games |
| Evolution Gaming | 7 | Side bet options, payout rates | Live dealer games |
| Yggdrasil | 8 | Bonus buy features, multiplier values | Slots |
This table shows that Playtech has the most variations in their games across different casinos. Yggdrasil tends to keep their games more consistent.
RTP Variations
RTP (Return to Player) is a big area where games change. RTP is the percentage of money that goes back to players over time. The same game might have:
- 96.5% RTP at Casino A
- 94.2% RTP at Casino B
- 92.8% RTP at Casino C
This means players at Casino A will, on average, get more money back than those playing at Casino C. This is a big deal for your chances of winning.
How to Check for Bonus Mechanics Differences
You can find out if a game has different bonus features at different casinos. Here are some ways:
- Read the game rules at each casino.
- Check the RTP information (usually found in game info).
- Try the game in free play mode first.
- Look for “exclusive version” labels.
- Check casino forums where players discuss these differences.
Many players skip these steps. They just start playing without checking. This can lead to surprise and disappointment.
Case Study: Book of Dead Variations
The popular slot “Book of Dead” by Play’n GO shows how this works in real life. At some casinos, it offers:
- 10 free spins for 3 scatter symbols
- Expanding symbols during free spins
- 96.21% RTP
At other casinos, the same game might have:
- 8 free spins for 3 scatter symbols
- Different expanding symbol mechanics
- 94.5% RTP
These changes can greatly affect your playing experience and winning chances.
Benefits for Players Who Pay Attention
Players who understand these differences can make better choices. They can:
- Pick casinos with the best version of their favorite games
- Understand the real odds of winning
- Find exclusive features that might be more fun
- Avoid casinos with worse versions of games
Smart players always check game details before they play with real money. This small effort can lead to better results and more fun.
In the end, knowing about these differences helps you be a smarter player. Casino game studios will likely continue this practice. The best thing you can do is stay informed and choose where to play based on which version of the game gives you the best chance to win.
