RTP<\/strong> is the share of all bets that a slot returns to players as winnings over the long run. An RTP of 96% means that out of every 100 coins staked, players collectively get 96 back and 4 stay with the casino.<\/p>\n

The key words here are \u201cover the long run\u201d. We checked this against the public data of 7\u00a0649 games and against 200\u00a0000 reproduced spins in each of 12 popular slots. Below: what RTP is, how to read it and what not to expect from it.<\/p>\n

What RTP is<\/h2>\n

RTP stands for Return to Player. It is the percentage of all bets made in a game that the game pays back as winnings. It is also called the payout percentage or the return percentage.<\/p>\n

What matters is who gets the money back: all players together, not each one individually. One player lands a big win, hundreds of others get nothing. Summed over millions of spins, it comes out at the stated percentage.<\/p>\n

RTP is a property of the game itself. It does not depend on the time of day, on how much you have already lost, or on who played before you.<\/p>\n

How RTP is calculated: formula and example<\/h2>\n

The formula is simple:<\/p>\n

RTP = all payouts \u00f7 all bets \u00d7 100%<\/strong><\/p>\n

An example. A million spins at one coin each were made in a slot \u2014 1\u00a0000\u00a0000 coins staked in total. The game paid out 960\u00a0000 coins in winnings. RTP = 960\u00a0000 \u00f7 1\u00a0000\u00a0000 \u00d7 100% = 96%.<\/p>\n

In practice a studio does not wait for a million real bets. RTP is built into the game\u2019s maths in advance and checked with simulations. On platforms with open maths it is an exact number: the sum of all possible payouts weighted by their probabilities. That is how the games work that we examined in our piece on the Stake Engine platform - Stake engine<\/span><\/a>.<\/p>\n

RTP and the house edge<\/h2>\n

Everything that is not returned to players stays with the casino. This share is called the house edge (the casino\u2019s advantage) and is calculated simply: 100% minus RTP.<\/p>\n\n\n\n\n\n\n\n\n\n
RTP<\/th>\nHouse edge<\/th>\nAverage cost of 1\u00a0000 spins at one coin each, in coins<\/th>\n<\/tr>\n<\/thead>\n
99%<\/td>\n1%<\/td>\n10<\/td>\n<\/tr>\n
97%<\/td>\n3%<\/td>\n30<\/td>\n<\/tr>\n
96%<\/td>\n4%<\/td>\n40<\/td>\n<\/tr>\n
94%<\/td>\n6%<\/td>\n60<\/td>\n<\/tr>\n
90%<\/td>\n10%<\/td>\n100<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The difference between 96% and 94% looks small \u2014 just two percentage points. But for the player it is 4 coins versus 6 out of every hundred: the game costs one and a half times as much. That is why it is easier to compare not RTP itself but what stays with the casino.<\/p>\n

The \u201caverage cost\u201d is exactly that \u2014 an average. In a real session the result can be much worse or much better. Why \u2014 see the next section.<\/p>\n

Why an RTP of 96% does not mean \u201cI get 96 back out of 100\u201d<\/h2>\n

Because payouts are distributed unevenly. Most spins bring nothing, and a noticeable part of the return comes from rare big wins.<\/p>\n

According to the data for 7\u00a0486 games on the Engine platform, in a typical game out of 100 spins about 71 are dead, about 19 pay less than the bet and only about 10 return the bet or more. The RTP, meanwhile, is an honest 96\u201396.7%.<\/p>\n

We reproduced 200\u00a0000 spins in each of 12 slots from the top rows of the Stake lobby and cut them into sessions of different lengths. The session budget equals the number of spins; the bet is one coin.<\/p>\n\n\n\n\n\n\n\n\n
Session length<\/th>\nWhat is left of the budget in a typical session (range across 12 games)<\/th>\n<\/tr>\n<\/thead>\n
100 spins<\/td>\n10 to 43%<\/td>\n<\/tr>\n
1\u00a0000 spins<\/td>\n54 to 85%<\/td>\n<\/tr>\n
10\u00a0000 spins<\/td>\n70 to 101%<\/td>\n<\/tr>\n
all 200\u00a0000 spins<\/td>\n77 to 105%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Even over 200\u00a0000 spins \u2014 years of play for one person \u2014 the actual return in nine games out of twelve turned out below the stated RTP, in two it was above, and in only one did it match. There is one reason: the biggest wins, which carry part of the RTP, simply did not land in that time.<\/p>\n

The longer the distance, the narrower the spread. Here is one slot \u2014 Private Jet with an RTP of 96.7%: the range in which the result fell for eight sessions out of ten.<\/p>\n

Over 100 spins a typical session returned 37% of the budget, and eight sessions out of ten fell between 16 and 231%. Over 10\u00a0000 spins it was already 92%, with a range of 79 to 115%. The game approaches the stated 96.7%, but slowly.<\/p>\n

RTP and volatility: what is the difference<\/h2>\n

RTP answers the question \u201chow much comes back on average\u201d. Volatility answers the question \u201chow exactly\u201d: often and in small amounts, or rarely and in big ones.<\/p>\n\n\n\n\n\n\n\n\n\n

An example from the same data. The slot Lazy Vampire has five published variants of one mode with the same RTP and different volatility. After 100 spins a typical session keeps from 13% of the budget in the harshest variant to 72% in the softest.<\/p>\n

That is why two slots with the same RTP can feel completely different. More in our article on slot machine volatility - Slots volatility<\/span><\/a>.<\/p>\n

What RTP counts as high<\/h2>\n

Instead of guessing, we looked at how base-mode RTP is distributed across 7\u00a0649 games.<\/p>\n\n\n\n\n\n\n\n\n\n
Base-mode RTP<\/th>\nGames<\/th>\nShare<\/th>\nHow to rate it<\/th>\n<\/tr>\n<\/thead>\n
below 94%<\/td>\n195<\/td>\n3%<\/td>\nLow<\/td>\n<\/tr>\n
94 to 95.99%<\/td>\n667<\/td>\n9%<\/td>\nBelow usual<\/td>\n<\/tr>\n
96 to 96.7%<\/td>\n6\u00a0448<\/td>\n84%<\/td>\nStandard<\/td>\n<\/tr>\n
above 96.7% and up to 97.99%<\/td>\n280<\/td>\n4%<\/td>\nAbove usual<\/td>\n<\/tr>\n
98% and above<\/td>\n59<\/td>\n1%<\/td>\nRare<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The conclusion is simple: 96\u201396.7% is not a \u201chigh RTP\u201d but the norm. Truly high values start at 97% and are rare.<\/p>\n

And a high RTP does not make a game soft. The slot Waylanders Forge has an RTP of 98% \u2014 the highest among the 12 we checked. Yet after 100 spins a typical session kept 15% of the budget in it, and over all 200\u00a0000 spins the game returned 77%.<\/p>\n
