Find the multiple in the offer’s terms. If a game’s house edge is not published, the result below is only as good as your estimate. Presets are illustrations, not any platform’s rules.

On average, betting through ₹510 costs about ₹15, which leaves the ₹51 bonus worth about ₹36. That is an average: the swing is about ± ₹50, and the chance of running out of balance first is not small if it shows above zero. At these odds the bonus stops paying for itself above about 33×.

Chances use a normal approximation and treat the balance as a continuous walk, so read them as sizes of risk, not exact percentages.

Nobody can say what a ₹51 bonus is worth without its terms, because the worth depends on the multiple and on the game. This page works one illustration through: if the terms asked for 10× on the bonus, you would bet ₹510 over 102 rounds and lose about ₹15 on average while doing it.

The example assumes a crash-style game that returns 97% on average, a figure often quoted for such games, so it keeps 3%. Copies can differ, so use the return your own app states.

Worked through for this offer: On average, betting through ₹510 costs about ₹15, which leaves the ₹51 bonus worth about ₹36. That is an average: the swing is about ± ₹50, and the chance of running out of balance first is not small if it shows above zero. At these odds the bonus stops paying for itself above about 33×. Take the multiple from the offer itself and the game’s return from your own app, and type them into the calculator above.

Nothing you enter leaves your phone, and the calculator knows no platform’s terms: the answer is only as good as the numbers you give it.

Common questions

How much must I bet to withdraw a small bonus?

Multiply the multiple in the terms by the base the terms name. A 10× multiple on a ₹51 bonus is ₹510 of betting if the base is the bonus alone, and more if the base includes your deposit. The terms say which.

Can a small bonus be worth taking?

On average it is worth the bonus minus the cost of betting through it, so a low multiple on a game that keeps little can leave something. A high multiple or a game that keeps more can leave nothing. The table above shows the same offer at six multiples.

Does this calculator know the terms of any bonus?

No. We have not seen the terms of any offer. You type in the bonus, the multiple and the game’s odds, and the answer is only as good as those numbers. Take them from the offer itself and from your app.

What return should I use for a crash-style game?

Use the figure your own app states. A return of 97% is often quoted for games of this type, which means the game keeps 3%, but copies can return less. Type your app’s figure into “My own house edge” as 100 minus the return.
