Mobile Web · Game Designer · IAP Purchase Confirmation guide
Use a browser-playable Mobile Web context to produce an annotated player-flow specification. Own screen hierarchy, offer timing, readable choices, and visible feedback; treat the result as a workflow prototype, not proof that native billing is connected.
Create this game flow
Focused keyword and player case
Prototype a confirmation panel that keeps the item, exact Koin price, balance, Confirm, and Cancel visible together. The game designer reviews consent, duplicate input, low balance, and safe cancellation and delivers an annotated player-flow specification. Acceptance means a player can preview the offer, decline it, recover from low balance, and explain the delivered result without coaching.
Use the focused IAP Purchase Confirmation hub for an authentic screenshot, direct playable result, and the complete purchase-state checklist. Gameplay evidence supports placement testing; it does not prove a live transaction.
Start with player motivation and the core loop. The item should support a goal players already understand rather than remove deliberately created frustration.
Design for the input, layout, interruption, and return behavior players expect from mobile web games.
Mobile web is not the same as an App Store or Google Play binary.
Show one non-required item, its preview, specific Koin amount, current Koin balance, and ownership rule in a layout suited to mobile web games.
Write how to show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. Keep each change visible to the player rather than hiding it in technical state.
Make a player cancellation, too little Koin, pending, interrupted delivery, and reload visually distinct, with a safe next action.
Choose the offer moment, explain the game benefit, and protect the complete free path. Compare the experience before and after ownership. Use the prototype to resolve player-facing questions before creating platform integration tasks.
For a game designer, this purchase confirmation prototype should make every player action and clearly displayed outcome easy to evaluate. Write how to show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. Choose the offer moment, explain the game benefit, and protect the complete free path. Compare the experience before and after ownership. Use comfortably separated confirm and cancel controls, readable Koin amounts, and a layout that survives portrait, landscape, browser chrome, and an on-screen keyboard without hiding the item.
Simulate locking the phone, changing tabs, receiving a call, and returning with a slow connection. The player should see one understandable result and retain a safe route back to play.
A mobile browser prototype is not an App Store or Google Play binary. Native billing APIs, device identity, refunds, entitlements, and submission need separate implementation and review.
Run the game without opening the purchase choice, then run it with the item. Compare pacing, motivation, difficulty, and recovery so the offer supports play instead of repairing frustration that was added deliberately.
Describe what changes on screen, how long it lasts, where it appears, and what remains available without it. Replace value labels such as better or premium with rules a player can observe.
Check what the player was doing immediately before the offer and where cancel returns them. The item should arrive after enough context to understand it, but never during a time-critical or emotionally pressured action.
The confirmation should repeat the selected item, exact Koin amount, visible Koin balance, remaining balance, and ownership rule without introducing a different offer. Test that behavior using mobile web games. Mobile web is not the same as an App Store or Google Play binary.
Use distinct actions with clear labels and enough spacing for the target input method. Returning to the game should never spend Koin. Test that behavior using mobile web games. Mobile web is not the same as an App Store or Google Play binary.
After confirmation, show a pending state and disable repeated input until the result is known. A slow response should not create duplicate grants. Test that behavior using mobile web games. Mobile web is not the same as an App Store or Google Play binary.
Choose the input and screen behavior for mobile web games. State the platform limit beside the prototype brief.
Result: An honest scope
Write how to show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. Describe the player action and visible response at each point.
Result: A clear purchase confirmation sequence
Show the item, exact price, balance, confirm, cancel, pending, success, and delivery without payment-provider screens.
Result: A complete player journey
Choose the offer moment, explain the game benefit, and protect the complete free path. Compare the experience before and after ownership.
Result: Game designer focus
Play cancellation and a full session without purchase. Check timing, value, competitive impact, and whether the item matches the delivered result. Repeat the test after interruption and reload.
Result: A stable prototype
Create touch-first play in a mobile browser for a game designer. Focus the IAP prototype on show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. Use a direct Koin item transaction with preview, exact price, confirmation, cancel, insufficient balance, success, delivery, and reload behavior. The game designer must be able to connect the offer to the core loop and player motivation. Do not add subscriptions, payment-provider UI, revenue analytics, or native platform claims. State this boundary: Mobile web is not the same as an App Store or Google Play binary.
Keep the item optional. Show its full price in Koin, visible Koin balance, confirm, cancel, low-balance, success, visible delivery, and reload states.
Own screen hierarchy, offer timing, readable choices, and visible feedback. Coordinate adjacent work, but keep the page's acceptance artifact specific to this role.
Deliver an annotated player-flow specification that records consent, duplicate input, low balance, and safe cancellation, named owners, failure states, and the next production verification step.
No. Production release still requires authenticated records, security, refunds, platform compliance, monitoring, and support procedures.
