The Bought Round / the buy
one round bought at a fixed price
The feature buy: one round, one price
A feature buy replaces the ordinary route to a game bonus with a purchase: you pay a fixed multiple of the base stake and the round pays the feature immediately, without waiting for it to trigger. The price is set by the game, not chosen by the player, and in the sampled games it averaged 101 times the stake. This page is about what that price is and what it buys.

The control platesample A / 1,200 extra-stake rounds, four controls
feature buy100x stakeBuys one whole round at a fixed price. The stake moves from 1x to 100x in a single decision; the return is the bought round's, not the base game's.
ante bet+25% per spinRaises the price of every spin a little and the stated chance of reaching the feature a lot. It makes a non-triggering spin dearer and can make the route to the feature cheaper.
super stake2x per spinDoubles the stake for roughly double the quoted chance. It changes the size of the bet and the variance, not the expected cost of reaching the feature.
gamble0 until a winCosts nothing to be offered, then stakes a win on a double-or-nothing. It is the only control here that can take money already won and put it back at risk.
Direct answerA feature buy charges a fixed multiple of the base stake - a mean of 101 times it across 480 invented buys - and pays the game feature immediately instead of waiting for it to trigger, with no further stake. The price is chosen by the game rather than the player, and the buy usually publishes a return of its own, so the round it buys is priced separately from the base game.

What the price is not
The price is not the value of the feature. A buy at 100.00 that returns 96.50 on average is priced above its average return by the edge - here 3.50. That gap is the same edge the base game carries, restated at the buy price. So the honest way to read a buy is as a stake multiplier: it turns a 1.00 spin into a 100.00 decision and leaves the mathematics where they were. Two consequences follow. The swings get large, because one decision now carries a hundred spins of stake. And the buy does not make a losing game a winning one; it makes a single round of a losing game into a larger single round of the same game.
Why the price is about the average cost of the feature
the feature triggers on average once every 100 spins
at 1.00 a spin the route costs 100.00
and it returns the feature value 96.50 on average
the buy sells exactly that round
for 100.00
and returns 96.50 on average
so the price tracks the average route,
the 3.50 gap is the edge on the purchase,
and the buy changes how the round is reached
rather than what the round is worth
the same feature, two routes:
spin until it comes small stakes, many decisions, high patience
buy it one large stake, one decision, no patience
Before pressing a buy
- Read the price as a multiple of your base stake, not as an amount in isolation.
- Find the published return of the buy; it may differ from the base game.
- Check the maximum win, because a 100x price against a 5,000x cap is a 50x ceiling.
- Check whether the bought round counts toward wagering, because it often does not.
- Check the eligibility rules; a buy made from bonus funds may be barred.
This desk names no real game, studio or operator and prints invented prices. Feature prices, published returns and eligibility rules are set by each game and its operator and differ widely; nothing here is advice on whether to buy a feature or on whether any particular price is fair.
