The ante bet: a little more on every spin

An ante bet adds a percentage to the stake of every spin in exchange for a stated improvement in the chance of reaching the feature. In the sampled games the uplift averaged a quarter of the stake and the games claimed up to twice the chance. The ante is the control that can lower the cost of reaching a feature and raise the cost of every spin that does not - at the same time.

base route to a feature: 100.00
ante route to a feature: 62.50
break-even improvement: more than 25%

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.

four controls, one thing in common: each changes what a round costs, and none changes what it can return beyond the game's own mathematics.

Direct answer

An ante bet adds a percentage to the stake of every spin - 25% on average in 300 invented antes - in exchange for a stated improvement in the chance of reaching the feature. If the ante doubles the chance, the average cost of reaching a feature falls from 100.00 to 62.50, but every spin that does not trigger costs a quarter more. It reduces the cost of the route, not the cost of the spins.

Two prices moving at once

The ante is the only control here that changes two figures in opposite directions. The cost of each spin rises by the uplift, so 100 spins at a 25% ante cost 125.00 instead of 100.00. The route to the feature shortens, because the chance rises, so the number of spins needed for one trigger falls. Whether the ante helps depends only on which of the two moves faster: if the chance rises by more than the price, the route gets cheaper; if by less, it gets dearer.

The ante, both directions base game: a 1 in 100 chance of the feature per spin the route without an ante 100 spins x 1.00 = 100.00 spent the route with a 25% ante and a doubled chance 50 spins x 1.25 = 62.50 spent so the route is cheaper by 37.50 but the spins that do not trigger 100 spins x 0.25 extra = 25.00 more spent so the ante is a trade: shorter route, dearer route cheaper route, dearer boredom the break-even is exact: the chance must rise by more than the uplift 25% price, 25% chance -> no change at all 25% price, 100% chance -> the 62.50 route above

what the ante does at different chance improvements
chance improvement	spin price	spins to a feature	cost to a feature
none (1 in 100)	1.25	100	125.00
x1.25 (1 in 80)	1.25	80	100.00
x2 (1 in 50)	1.25	50	62.50
a 25% price needs more than 25% chance to pay for itself			62.50

Reading an ante

Write down the uplift as a percentage of the base stake.
Write down the stated chance improvement the game quotes.
Compare them: the ante pays only if the chance rises by more than the price.
Remember the ante is charged on every spin, not only successful ones.
Note that a stated chance is a quoted figure; this desk assumes it holds and does not verify it.

This desk names no real game or studio and prints invented uplifts and chances. The stated improvement in chance is a figure the game advertises, and no page here verifies it against a real game; the arithmetic only shows what such a figure would be worth if it held.
