A closer look: look at the numbers from the first reel onward.
PLAY / EXPLORE / UNDERSTANDReturn to player is an expectation
This is part of understanding the current release. RTP expresses the expected total award divided by the total paid wager over a very large number of rounds. This site calculates it from the actual symbol weights, tables and feature rules. It is not the percentage of spins that show a win or an assurance about a short session. The examples describe virtual-credit play within this release. Additional context is available in the site’s related guides.
Include every attached feature
This reference concerns the supplied Slots games. A paid round can contain an initial spin plus free spins, a respin, a collection or a pick award. The published full-round RTP includes those attached results. Their awards are compared with the original paid wager, since feature steps do not deduct another one. A mode’s own paytable remains the reference for its awards.
Keep refills outside the ratio
One useful detail is explained below. Starting credits and free refills are not game awards. Counting them in the return calculation would artificially inflate a player's observed result. The statistics therefore track paid wagers and actual awarded credits separately from any free balance added for practice. The examples describe virtual-credit play within this release. Review the relevant page before using another mode.
Calculate ordinary line return
For a line, the calculation enumerates possible symbol sequences with their actual weighted probabilities and the line's highest valid award. Expected awards can be added across the 20 paths even when those paths share cells. This uses linearity of expectation without pretending the paths are independent. A mode’s own paytable remains the reference for its awards. Additional context is available in the site’s related guides.
Account for the feature rules
The distinction matters when comparing games. Free spins and retriggers use their expected total number of steps. The respin calculation preserves the Wild probability inherited from the first grid. Picking uses the mean of one selected tile, while collection uses the possible locked counts and remaining attempts, including resets. The same definitions apply on a phone and a desktop browser.
Use the table for this release
Use this point when reading a result. The table on this page shows the computed figures for each playable mode. They are generated from the same rule definitions as the game. Clearing the site's HTML cache changes presentation assignments and text choices; it does not reroll these mathematics or modify the symbol weights. The same definitions apply on a phone and a desktop browser. Additional context is available in the site’s related guides.
Distinguish calculation from certification
The distinction matters when comparing games. The figures are internal mathematical calculations supplied with this original virtual-credit game. This website does not claim that a regulator, casino laboratory or third-party auditor has certified them. The local game can be inspected in the program files, including the reproducible math-report tool. The examples describe virtual-credit play within this release. Review the relevant page before using another mode.
Interpret your own short sample
This reference concerns the supplied Slots games. Observed awards divided by wagers can be far above or below the theoretical ratio in a small record. An active bonus can also leave some of a round's awards pending. A published average cannot determine the next result or remove the random variation in a short visit. A mode’s own paytable remains the reference for its awards. Review the relevant page before using another mode.
