Free Spins or Spinbonusrunden are almost nowadays almost the basic equipment of online slots. This bonus feature is generally triggered by the appearance of three or more “scattersymbols on the reels. In most cases, this structure or the format for free spins is fixed and these are triggered automatically, without the interaction of the player, when the aforementioned conditions are met.

Some online gambling software developers offer players a choice of free spins. This option allows the player to choose between a combination of multipliers and the number of free spins. A recently released online slot, Mile High from Vegas Technology, has this option. When the first option is selected, the player can opt for 12-free spins with a 2fold multiplier, the second is 8-free spins and a 3-fold multiplier, and the third option offers 5-free spins with a 4-fold Multiplier. Now, however, the question arises as to which of the listed options the player should choose …

In general one should be aware that one can not predict the possible profit or the payout in any of the options. The only way to create a kind of statistics would be to trigger 10,000 spins with all the available options and to keep a precise account of the gains made – an impossibility. It is very likely that all options allow more or less an equal payout.

A simple calculation, however, can help to eliminate bad options. However, certain conditions or conditions must be assumed for this calculation. Each of the options must be played with identical reels. This means that the number of each wallet type or symbol on the roller, regardless of which option was selected, would be identical. This is followed by the expected payout for each spin of the respective options.

Assume that the expected payout per spin is defined as P. In the first option we get 12-free spins and a 2-fold multiplier and the expected total payout would be (12 x 2 x P) or (24 x P).

The second option provides 8-free spins and a 3-fold multiplier; The expected total payment would be (8 x 3 x P) or (24 x P).

The third option offers 5-free spins and a 4-fold multiplier. The expected total payment would be (5 x 4 x P) or (20 x P).

Under these conditions, the third option would provide the lowest total expected payout as far as theory is concerned. Of course, all expected payouts are solely dependent on chance.

However, for reasons of fairness, it must be noted that these options have been simplified in order to be able to display the costing. The current calculations are a bit different. The payouts would not occur every time as in the examples; But only with the help of a “wild” symbol.

Under the given conditions and our assumption, however, this would not affect the calculation. However, the second adjustment is more relevant. There are only two “wild” symbols in the online slot Mile High. If both were to occur, the calculated multiplication values ​​would be 4, 9 and 16 respectively. However, this can not be calculated exactly since we do not know the probability of the “wild” symbols. No matter what would happen in this case; The third option in this case, compared to the first two options, is theoretically the better choice.
