The questions, in full

Ten questions a reader tends to ask about the extra-stake controls - what a feature buy is, why it costs what it costs, whether it is better value than spinning, what the ante and the super stake change, whether a gamble is fair, why a bought round may not count for a bonus, and where the desk stops. Each answer stands on the invented samples and repeats only what another page already shows.

Direct answer

A feature buy charges a fixed multiple of the base stake for one round of a game feature. Across 480 invented buys the mean price was 101 times the stake with a 96.5% return, so a 100.00 buy returns 96.50 on average - a 3.50 edge on the purchase. The ante, the super stake and the gamble change the price and the route differently, and a bought round often counts for nothing toward a wagering requirement.

a buy is a price, not a prize
the price and the return are different figures
an ante pays only if the chance beats the uplift
a matched super stake is a size choice
a gamble is near even money, not even
a bought round often counts for nothing

The questions, in full

q01

What is a feature buy?

A feature buy is a purchase of one round of a game feature at a fixed multiple of the base stake, instead of waiting for the feature to trigger. Across 480 invented buys the mean price was 101 times the stake; the price is set by the game and is the same for every player.

q02

Why is a buy priced at about a hundred times the stake?

The price tracks the average cost of reaching the same round by ordinary spins. If a feature arrives once every hundred spins on average, the route costs about 100 times the stake and returns the feature value, so a buy is priced near that figure rather than opposite to it.

q03

Is a buy better value than spinning?

It is about the same expected value by a different route. A 100.00 buy and an average route of 100 spins at 1.00 both cost about 100.00 for the same round and return the same average. The buy changes the size of the decision and its variance, not the value.

q04

Why is the buy price not the average return?

Because the price is what you pay and the return is what the round pays back. A 100.00 buy that publishes a 96.5% return comes back at 96.50 on average; the 3.50 difference is the edge on the purchase, not part of the price.

q05

What does an ante bet change?

An ante adds a percentage to the stake of every spin - 25% on average in 300 invented antes - against a stated improvement in the chance of reaching the feature. If the chance doubles, the route to a feature falls from 100.00 to 62.50, but every non-triggering spin is a quarter dearer.

q06

What does a super stake change?

A super stake multiplies the stake of every spin by a round figure and claims the same multiple of the chance. When the two match, the expected cost of reaching the feature is unchanged - 100.00 either way - so it changes the bet size and the variance rather than the price.

q07

Is a gamble a fair coin toss?

It is close to even money but not equal to it. Of 180 invented gambles on a 100.00 win, 84 doubled it and 96 lost it, a mean of 93.33 against 100.00 kept - a 6.67 edge, paid across the class of gambles rather than visible in one.

q08

Does a bought round count toward a wagering requirement?

Often not. Of 480 invented buys, 96 counted toward wagering and 384 counted for nothing, with 60 barred altogether because they were made from bonus funds or on an excluded game. The terms, not the game, decide this.

q09

Does the maximum win affect a buy?

Yes, because it caps what the price can buy. If a game pays at most 5,000 times the base stake and a buy costs 100 times the stake, the most one bought round can return is fifty times the price. Of 480 invented buys, 12 reached the cap.

q10

Where does this desk stop?

It stops at the price and the shape of an extra-stake round. It does not explain what a return figure means in general, what an interface says and permits, who builds a title, or the conditions on an offer - each of those is another desk - and it neither recommends nor discourages any control.
