How High Can Return to Player Percentages Go at Online Gambling Sites

As a trusted information source to UK players, TheSlotzBuzz provides factual and reliable details needed to make well-informed choices. It’s a new modern era in which people rely on reviews and articles before making decisions or choices. To offer the same information regarding online games at gambling sites, not only the use of mathematical measurements are necessary but also effective ways to communicate it to anyone who enjoys online casino games.

Return to player (RTP) is not only a fascinating topic but also a useful reference point, the UK Gambling Commission requires all games at online and land-based casinos to clearly display return to player rates. At the same time, the return to player rate is an average percentage across multiple rounds, uses, or spins and not a guide for every time a particular slot game is played. Generally return to the player is measured across around 100,000 or more rounds.

Apart from the mathematical advantage a lot of psychology goes into how players view a game, in terms of past experiences a big win in the first session, or failure to trigger the main bonus feature in around 200 or 300 spins can leave a lasting impression. How an online slot plays is a complex issue once human nature and mathematics are considered.

Online Casino Games vs Land-Based Casino Game

Games at online casinos fare higher when it comes to the return to player rates, mainly due to lower overheads and cheaper operating costs. Online casino game developers offer slots with a return of 98% or in some instances even higher.

Land-based casinos offer an overall experience that may include access to refreshments, VIP exclusive gambling lounges and other comps. Playing slots in world-renowned establishments such as Macau or Las Vegas casinos is part of a dream holiday and RTP percentages, win variance, house edge, and hit frequency are less important. The ambience of the gambling site and the social aspect plays a much bigger part.

Online Slots RTPs with Progressive Jackpots

In progressive jackpot slots, a small portion of the wager goes towards the progressive jackpot pool/s. A part of the return to player percentage is also reserved for jackpots, which explains the lower return to player rate. Mega Fortune, for example, is a highly popular progressive jackpot by NetEnt with an overall return to player of 96.5%, of which the base game is 62.8%, bonus game 9.3%, free spins 16.8% and 7.6% is reserved for jackpots.

The same is evident in comparing slot games offering huge jackpots by some of the other premier software developers in casino gambling. Looking at the differences between some of the best-known online slot game standards and jackpot versions offering the same features highlights the significant differences.

  • NetEnt Progressives: Mega Fortune 96.6% with progressive jackpot 89.9% without, Hall of Gods 95.7% with progressive and 88.7% without.
  • Microgaming Progressives: Mega Moolah progressive 93.42% without 88.12%,
  • Playtech Progressives: Jackpot Giants progressive 94.22% without 91.24%, Age of the Gods progressive 95.02% without 94.03%.

Gaming machines and slot machines can offer different return to player percentages at online casinos. Previously, only the game creator could decide the game or slots return to play, several online software providers now add return-to-player ranges instead of fixed return-to-player percentages.

Return to player ranges enables casinos to select from a range in general of between 94% to 97%. It explains why a specific game or slot can have a higher or lower return to player value at different online casinos. For example, Play’n Go offer several versions of the slots and other games with varying return-to-player rates, 7 Sins slot could offer 95% at one operator and 96% at another. Online casinos regulated by the UKGC must display the correct RTP to players.

Is there a legal limit to how high and low the RTP can go in a slot game?

The United Kingdom Gambling Commission lists the legal requirements for gaming or gambling machines and casino games at land-based and online casinos. No minimum or maximum return to player requirements are listed although the minimum average return to player percentage must be available to players for each game.

The minimum return to players displayed also needs to be verified by a UKGC accredited test house or the game manufacturer or game developer. The theoretical return to player percentage must indicate the average measured across a large number of spins or games, which vary over sessions due to game volatility.

The Malta Gaming Authority lowered its minimum return to player required threshold from 92% in 2021 to 85%. The reason for the change according to the MGA was to bring it in line with that of operators in the land-based sector.
