Bonus Buy at Zora: calculate the price of one confirmation
Bonus Buy is an optional purchase of a game feature where that function is offered. It is not the same as receiving a promotional bonus from Zora. The game’s purchase screen and the account’s active promotion rules therefore answer two different questions: what does the feature cost, and is that purchase permitted with the current balance?
An illustrative feature priced at 80 times the base stake costs €16 when the base stake is €0.20. At €1 it costs €80. A small-looking stake label can therefore conceal a much larger confirmation amount. Read the full purchase price again after changing denomination, stake or feature tier.
A purchased feature is not a guaranteed profitable feature. Its payout can be lower than the price, and the chance distribution can differ from ordinary spins. Do not use a previous feature result as a promise for the next purchase. If separate RTP figures are displayed for purchase modes, record the figure for the exact selected mode.
With an active casino bonus, check feature restrictions before opening the confirmation screen. A general maximum stake does not automatically tell you whether a feature purchase is allowed. If the terms are unclear, leave the purchase unconfirmed and ask Zora. This protects the decision from an expensive assumption; it does not eliminate the normal risk of the game.
Understand the purchase as a separate priced action
The term bonus appears both in operator promotions and in game features, but those uses describe different things. A welcome reward is a campaign attached to the account. A purchased feature is an instruction inside a game that commits a stated amount. Finding a Bonus Buy button therefore does not establish that the action is funded by a promotional reward or that it is permitted during that reward's use.
Read the confirmation as a purchase summary: selected feature tier, base stake, price multiplier and final currency amount. If any of these changes when you switch a setting, review the complete summary again before accepting.

Compare ordinary rounds and a purchase without false equivalence
A hypothetical €20 feature price equals the stake total of one hundred ordinary €0.20 rounds. That equality concerns expenditure only. It does not mean the ordinary rounds would trigger the feature once, or that their possible results have the same distribution as a purchase. The routes can involve different rules, and a price ratio does not reveal a trigger probability.
For the same reason, a feature returning €12 after a €20 purchase has a net result of minus €8. A bright win animation displaying €12 does not turn the entire purchase into a profit. Compare the completed result against the amount actually charged.
A promotion can restrict a mode inside an eligible title
Game-level eligibility and mode-level eligibility need separate confirmation. An offer may identify a title while adding exclusions for optional actions, or it may define a maximum commitment in a way that requires further explanation for purchases. Do not conclude that a button's technical availability overrides the campaign terms.
If support clarifies a restriction, keep the answer with the campaign name and exact game mode. A general answer about ordinary spins is not automatically an answer about a multi-stake feature purchase. This record matters because the underlying game and the account promotion are two distinct sources of conditions.
Use the round record to verify what happened
After a purchase, identify the debit associated with the selected feature and the final recorded return. Intermediate counters may show feature progress or component amounts, not separate payments. Do not add an amount again merely because it appears both during the animation and in the final result.
If the screen disconnects, preserve the round identifier before starting anything else. Repeating the purchase is not a test that the first one failed; it can create another charged round. The next step is to establish the status of the original instruction, not to infer it from whether a familiar animation is still visible.
